Would you like to inspect the original subtitles? These are the user uploaded subtitles that are being translated: 1 1 00:00:02,050 --> 00:00:04,880 So let's install Flutter then. 2 2 00:00:04,880 --> 00:00:07,090 And the installation actually differs 3 3 00:00:07,090 --> 00:00:09,630 between Mac OS and Windows. 4 4 00:00:09,630 --> 00:00:12,190 For the rest of the course the code we write 5 5 00:00:12,190 --> 00:00:13,690 and so on will be the same. 6 6 00:00:13,690 --> 00:00:15,820 But here for the installation, it differs. 7 7 00:00:15,820 --> 00:00:18,250 So therefore, in this video, 8 8 00:00:18,250 --> 00:00:22,570 we'll set up Flutter and all the surrounding packages 9 9 00:00:22,570 --> 00:00:24,710 and dependencies we need for Mac. 10 10 00:00:24,710 --> 00:00:26,050 And then the next video, 11 11 00:00:26,050 --> 00:00:27,760 we'll do the same for Windows. 12 12 00:00:27,760 --> 00:00:30,060 So if you are a Windows user, 13 13 00:00:30,060 --> 00:00:31,990 you can simply skip this video. 14 14 00:00:31,990 --> 00:00:33,430 And if you are a Mac user, 15 15 00:00:33,430 --> 00:00:35,360 you can skip the next video. 16 16 00:00:35,360 --> 00:00:37,850 So let's proceed with the Mac setup then. 17 17 00:00:37,850 --> 00:00:42,850 on Flutter.io, you can simply click on get started, 18 18 00:00:43,430 --> 00:00:46,000 and then choose install on Mac OS. 19 19 00:00:46,000 --> 00:00:47,340 By the way, if you're on Linux, 20 20 00:00:47,340 --> 00:00:48,940 the steps are pretty much the same. 21 21 00:00:48,940 --> 00:00:51,140 But you can also click on install on Linux, 22 22 00:00:51,140 --> 00:00:52,640 to see them in detail. 23 23 00:00:52,640 --> 00:00:55,860 And that's in general what I would recommend. 24 24 00:00:55,860 --> 00:00:58,200 Go through these steps in detail. 25 25 00:00:58,200 --> 00:01:01,040 The good thing is you can read them here. 26 26 00:01:01,040 --> 00:01:02,430 And I strongly recommend, 27 27 00:01:02,430 --> 00:01:04,750 following along here and reading these, 28 28 00:01:04,750 --> 00:01:06,830 whilst you also watch this video, 29 29 00:01:06,830 --> 00:01:10,010 or whilst you are going through the installation process. 30 30 00:01:10,010 --> 00:01:15,010 Because A, some tiny steps could change over time. 31 31 00:01:15,080 --> 00:01:18,870 And B, this is a great way of resolving issues, 32 32 00:01:18,870 --> 00:01:21,800 since there might be something you overlook in the video. 33 33 00:01:21,800 --> 00:01:24,830 Which you can then simply read about in this article. 34 34 00:01:24,830 --> 00:01:26,490 So let's continue. 35 35 00:01:26,490 --> 00:01:29,140 First of all, let's check the system requirements. 36 36 00:01:29,140 --> 00:01:30,650 Well, we need the operating system, 37 37 00:01:30,650 --> 00:01:32,130 Mac OS obviously. 38 38 00:01:32,130 --> 00:01:34,300 Enough free space on our disk. 39 39 00:01:34,300 --> 00:01:37,260 And then we depend on these command line tools, 40 40 00:01:37,260 --> 00:01:40,410 which actually should all be available by default. 41 41 00:01:40,410 --> 00:01:43,400 Now Git might not be, 42 42 00:01:43,400 --> 00:01:47,300 so it's a good idea to download it before you get started. 43 43 00:01:47,300 --> 00:01:51,180 You can simply search for Git on Google, 44 44 00:01:51,180 --> 00:01:52,930 and then actually pick that first, 45 45 00:01:52,930 --> 00:01:57,080 or actually that second link to find the downloads page. 46 46 00:01:57,080 --> 00:01:59,900 And there simply choose Mac OS or Linux, 47 47 00:01:59,900 --> 00:02:01,040 depending on what you're on. 48 48 00:02:01,040 --> 00:02:04,610 And then, the download should start automatically. 49 49 00:02:04,610 --> 00:02:07,820 If it doesn't, you can simply click here obviously. 50 50 00:02:07,820 --> 00:02:09,920 And this will download an installer, 51 51 00:02:09,920 --> 00:02:12,180 for which you can simply work to install Git. 52 52 00:02:12,180 --> 00:02:14,220 which is a Version Management System, 53 53 00:02:14,220 --> 00:02:15,680 on your machine. 54 54 00:02:15,680 --> 00:02:18,530 Now you don't need to use that Version Management System, 55 55 00:02:18,530 --> 00:02:20,720 but Flutter uses it behind the scenes. 56 56 00:02:20,720 --> 00:02:23,020 This is why you need to have this available. 57 57 00:02:23,020 --> 00:02:24,473 Once you've got Git installed, 58 58 00:02:24,473 --> 00:02:26,810 with the help of that installer you can download. 59 59 00:02:26,810 --> 00:02:28,700 Which I showed you a second ago, 60 60 00:02:28,700 --> 00:02:30,610 you can proceed with these steps. 61 61 00:02:30,610 --> 00:02:33,440 And the next step is to actually download Flutter. 62 62 00:02:33,440 --> 00:02:35,810 Now, at the point of time recording this, 63 63 00:02:35,810 --> 00:02:37,800 the latest version is 0.3.2 beta. 64 64 00:02:39,685 --> 00:02:42,150 Chances are that when you're watching this, 65 65 00:02:42,150 --> 00:02:44,420 there's a higher version available. 66 66 00:02:44,420 --> 00:02:47,260 But the code we write will still be the same. 67 67 00:02:47,260 --> 00:02:50,450 So download the latest version you're seeing here of course. 68 68 00:02:50,450 --> 00:02:52,800 Now I'll go with this one. 69 69 00:02:52,800 --> 00:02:55,230 Simply download it to your machine. 70 70 00:02:55,230 --> 00:02:56,240 And this can take a while, 71 71 00:02:56,240 --> 00:02:57,900 as you can see it's quite a big file. 72 72 00:02:57,900 --> 00:02:59,900 So I will jump forward, 73 73 00:02:59,900 --> 00:03:03,093 to the point of time where this already is downloaded. 74 74 00:03:04,090 --> 00:03:06,150 The installation just finished for me, 75 75 00:03:06,150 --> 00:03:08,100 you can now simply unzip this. 76 76 00:03:08,100 --> 00:03:10,630 And you can do that with the command you see here, 77 77 00:03:10,630 --> 00:03:13,810 or simply well, click on that downloaded file. 78 78 00:03:13,810 --> 00:03:18,190 Simply open it in the folder where it was downloaded. 79 79 00:03:18,190 --> 00:03:20,940 Simply click on it down there. 80 80 00:03:20,940 --> 00:03:22,410 And then unzip this. 81 81 00:03:22,410 --> 00:03:24,190 Now this can take a couple of seconds of course, 82 82 00:03:24,190 --> 00:03:26,740 since it's a rather big file. 83 83 00:03:26,740 --> 00:03:28,550 Once it is unzipped, 84 84 00:03:28,550 --> 00:03:30,550 you have this Flutter folder. 85 85 00:03:30,550 --> 00:03:32,530 And now you should copy this somewhere, 86 86 00:03:32,530 --> 00:03:33,800 where do you wanna store this. 87 87 00:03:33,800 --> 00:03:36,010 Now this Flutter thing here, 88 88 00:03:36,010 --> 00:03:37,760 is an entire tool set. 89 89 00:03:37,760 --> 00:03:41,190 It's the SDK, the Software Development Kit, 90 90 00:03:41,190 --> 00:03:43,680 you need for developing Flutter apps. 91 91 00:03:43,680 --> 00:03:46,550 It includes a lot of dependencies Flutter needs. 92 92 00:03:46,550 --> 00:03:49,470 So this is really a central package of program, 93 93 00:03:49,470 --> 00:03:50,860 you should store in your machine. 94 94 00:03:50,860 --> 00:03:54,510 And you can copy it wherever you want on your machine. 95 95 00:03:54,510 --> 00:03:56,500 Now I got that tools folder, 96 96 00:03:56,500 --> 00:03:57,333 where I wanna have it. 97 97 00:03:57,333 --> 00:03:59,450 So I'll just drag it over there. 98 98 00:03:59,450 --> 00:04:02,490 And now with Flutter added to that folder, 99 99 00:04:02,490 --> 00:04:04,280 we can proceed with well, 100 100 00:04:04,280 --> 00:04:06,570 the installation or with using it. 101 101 00:04:06,570 --> 00:04:07,990 So the Flutter tool, 102 102 00:04:07,990 --> 00:04:11,200 is actually a tool we execute from the command line. 103 103 00:04:11,200 --> 00:04:14,530 Therefore, we need to add it to our path. 104 104 00:04:14,530 --> 00:04:17,020 The path is basically a global variable, 105 105 00:04:17,020 --> 00:04:19,360 which ensures that the Flutter program, 106 106 00:04:19,360 --> 00:04:21,270 or which ensures that any program, 107 107 00:04:21,270 --> 00:04:23,320 can be accessed through the command line. 108 108 00:04:23,320 --> 00:04:25,450 And we wanna configure the Flutter program 109 109 00:04:25,450 --> 00:04:26,820 to be found there. 110 110 00:04:26,820 --> 00:04:27,910 Now to be found there, 111 111 00:04:27,910 --> 00:04:31,070 we could execute this command in the command line. 112 112 00:04:31,070 --> 00:04:35,650 If we navigated into the newly created Flutter folder, 113 113 00:04:35,650 --> 00:04:37,960 or we do something which is seen 114 114 00:04:37,960 --> 00:04:40,100 a little bit further down the article. 115 115 00:04:40,100 --> 00:04:42,960 Here, we update our path permanently. 116 116 00:04:42,960 --> 00:04:44,270 Now how does that work? 117 117 00:04:44,270 --> 00:04:46,560 For that you should go into your user folder, 118 118 00:04:46,560 --> 00:04:49,370 and there you need to turn on the setting 119 119 00:04:49,370 --> 00:04:50,950 to see hidden files. 120 120 00:04:50,950 --> 00:04:53,750 You should then see that bash profile file. 121 121 00:04:53,750 --> 00:04:57,550 Important if you're on Mac OS Catalina or higher, 122 122 00:04:57,550 --> 00:05:01,480 It will not be a bash profile file, 123 123 00:05:01,480 --> 00:05:05,420 but a .zprofile file. 124 124 00:05:05,420 --> 00:05:07,180 It fulfills the same purpose, 125 125 00:05:07,180 --> 00:05:08,710 it's just a different name, 126 126 00:05:08,710 --> 00:05:11,480 and you should then edit that file. 127 127 00:05:11,480 --> 00:05:12,700 Another important note, 128 128 00:05:12,700 --> 00:05:14,980 if you see neither of these files. 129 129 00:05:14,980 --> 00:05:17,700 If you don't have such a profile file, 130 130 00:05:17,700 --> 00:05:20,720 whatever name it is for your Operating System. 131 131 00:05:20,720 --> 00:05:21,970 You can simply create it. 132 132 00:05:21,970 --> 00:05:24,070 Simply create a Text file, 133 133 00:05:24,070 --> 00:05:26,880 insert what we're about to insert in the next seconds, 134 134 00:05:26,880 --> 00:05:30,130 and then save it under .bash profile, 135 135 00:05:30,130 --> 00:05:33,397 for Mac OS older than Catalina, 136 136 00:05:33,397 --> 00:05:34,230 and .zprofile for Mac OS after Catalina. 137 137 00:05:38,980 --> 00:05:40,870 Now you can simply open that, 138 138 00:05:40,870 --> 00:05:43,160 with the normal Text editor app, 139 139 00:05:43,160 --> 00:05:45,920 or with any Text editor of your choice. 140 140 00:05:45,920 --> 00:05:47,680 If you're using the Text editor app, 141 141 00:05:47,680 --> 00:05:52,030 just make sure you're viewing this in plain text mode, 142 142 00:05:52,030 --> 00:05:53,890 not in rich text mode. 143 143 00:05:53,890 --> 00:05:55,860 So if you open this then. 144 144 00:05:55,860 --> 00:05:57,360 Let me make this a bit bigger. 145 145 00:05:58,440 --> 00:05:59,670 You can edit this file. 146 146 00:05:59,670 --> 00:06:02,300 And this basically configures path settings, 147 147 00:06:02,300 --> 00:06:03,870 for your terminal. 148 148 00:06:03,870 --> 00:06:07,150 For your command line tool on Mac or Linux. 149 149 00:06:07,150 --> 00:06:09,640 Now, we wanna add something here. 150 150 00:06:09,640 --> 00:06:11,160 We wanna add this line, 151 151 00:06:11,160 --> 00:06:14,074 which you can find in the installation steps. 152 152 00:06:14,074 --> 00:06:16,620 Simply add it at the bottom. 153 153 00:06:16,620 --> 00:06:19,600 And we need to replace this part here, 154 154 00:06:19,600 --> 00:06:21,880 with the actual path. 155 155 00:06:21,880 --> 00:06:26,280 The folder path to that Flutter tool on our machine. 156 156 00:06:26,280 --> 00:06:30,310 Now that of course depends on where you dragged it. 157 157 00:06:30,310 --> 00:06:34,370 For me, it can be found under users, 158 158 00:06:34,370 --> 00:06:38,510 then my username, then there's a development folder. 159 159 00:06:38,510 --> 00:06:40,810 And then there I created a tools folder. 160 160 00:06:40,810 --> 00:06:43,910 And again, you really have to pick your path there, 161 161 00:06:43,910 --> 00:06:46,740 where you dragged that Flutter tool. 162 162 00:06:46,740 --> 00:06:50,120 Can view that also by clicking on get info here, 163 163 00:06:50,120 --> 00:06:51,470 then you can see where it's found. 164 164 00:06:51,470 --> 00:06:55,930 In my case users, my user name, development tools. 165 165 00:06:55,930 --> 00:06:57,970 With that, simply save that file, 166 166 00:06:57,970 --> 00:07:01,530 and thereafter open your normal terminal app 167 167 00:07:01,530 --> 00:07:03,750 on Mac or Linux. 168 168 00:07:03,750 --> 00:07:05,160 Once you did open that, 169 169 00:07:05,160 --> 00:07:08,710 you should be able to run Flutter doctor. 170 170 00:07:08,710 --> 00:07:10,710 Now this is a tool which will also check, 171 171 00:07:10,710 --> 00:07:13,130 if you need to do something to make Flutter work. 172 172 00:07:13,130 --> 00:07:16,290 And it should at least do something, 173 173 00:07:16,290 --> 00:07:19,090 if you set up your Flutter installation correctly. 174 174 00:07:19,090 --> 00:07:21,600 By the way, the fact that my installation is 30 days old, 175 175 00:07:21,600 --> 00:07:22,820 we can ignore that here. 176 176 00:07:22,820 --> 00:07:26,240 Because we know we just downloaded the latest version, 177 177 00:07:26,240 --> 00:07:27,830 0.3.2 in my case. 178 178 00:07:27,830 --> 00:07:29,580 So this is all fine. 179 179 00:07:29,580 --> 00:07:32,130 Now this is already looking quite good here, 180 180 00:07:32,130 --> 00:07:35,320 because I actually have a decent setup. 181 181 00:07:35,320 --> 00:07:38,580 I'll still walk you through the remaining steps here though. 182 182 00:07:38,580 --> 00:07:40,700 So we updated our path. 183 183 00:07:40,700 --> 00:07:43,220 We now ran flutter doctor too. 184 184 00:07:43,220 --> 00:07:44,300 Now what we need to do is, 185 185 00:07:44,300 --> 00:07:46,350 we need to configure our system 186 186 00:07:46,350 --> 00:07:51,163 to be able to build iOS and or Android apps. 187 187 00:07:52,010 --> 00:07:54,690 For that, If you wanna build iOS apps. 188 188 00:07:54,690 --> 00:07:56,370 If you wanna test your app on iOS, 189 189 00:07:56,370 --> 00:07:59,180 and ultimately build it for that platform. 190 190 00:07:59,180 --> 00:08:00,820 You need to install Xcode. 191 191 00:08:00,820 --> 00:08:03,910 Which is Apple's development IDE, 192 192 00:08:03,910 --> 00:08:08,200 but also a absolutely required tool for building iOS apps. 193 193 00:08:08,200 --> 00:08:11,300 Even if you use Flutter and no native code for that. 194 194 00:08:11,300 --> 00:08:13,170 So install Xcode, 195 195 00:08:13,170 --> 00:08:16,350 by downloading it from the Mac App Store. 196 196 00:08:16,350 --> 00:08:18,570 And once you got installed, 197 197 00:08:18,570 --> 00:08:20,490 you need to make sure that you can use, 198 198 00:08:20,490 --> 00:08:23,230 the so called Xcode command-line tools. 199 199 00:08:23,230 --> 00:08:26,500 And this can be done by simply copy and pasting, 200 200 00:08:26,500 --> 00:08:29,170 this command into your terminal. 201 201 00:08:29,170 --> 00:08:31,250 So you can simply run this. 202 202 00:08:31,250 --> 00:08:33,993 You might be prompted to enter your password there. 203 203 00:08:35,630 --> 00:08:37,700 And then it might or might not do something, 204 204 00:08:37,700 --> 00:08:40,130 depending on whether you already configured this. 205 205 00:08:40,130 --> 00:08:42,900 It might prompt you to accept the license. 206 206 00:08:42,900 --> 00:08:45,310 Once you've completed this step, 207 207 00:08:45,310 --> 00:08:48,210 you can continue to step number three. 208 208 00:08:48,210 --> 00:08:49,510 And execute this command, 209 209 00:08:49,510 --> 00:08:52,800 to accept the license agreements of Xcodebuild. 210 210 00:08:52,800 --> 00:08:54,850 Which is the build tool we're going to use. 211 211 00:08:54,850 --> 00:08:57,340 Now here we can simply scroll to the bottom, 212 212 00:08:57,340 --> 00:09:00,693 which can be sped up by hitting space a couple of times. 213 213 00:09:01,660 --> 00:09:04,013 And then type agree down there. 214 214 00:09:05,070 --> 00:09:07,340 Now with that out of the way we can continue. 215 215 00:09:07,340 --> 00:09:09,880 And we can bring up the iOS simulator. 216 216 00:09:09,880 --> 00:09:13,710 Which simply is iPhone running on our machine. 217 217 00:09:13,710 --> 00:09:15,870 It can be started with this command. 218 218 00:09:15,870 --> 00:09:18,900 You could also start it from within the Xcode by the way. 219 219 00:09:18,900 --> 00:09:21,310 But I will simply start it with this command. 220 220 00:09:21,310 --> 00:09:25,690 Open dash A Simulator with a capital S. 221 221 00:09:25,690 --> 00:09:27,760 And now what this should do, 222 222 00:09:27,760 --> 00:09:32,560 is it should bring up this iOS simulator here. 223 223 00:09:32,560 --> 00:09:34,080 Now this is the device running, 224 224 00:09:34,080 --> 00:09:37,530 you can change the type of phone you're emulating here, 225 225 00:09:37,530 --> 00:09:40,900 from that menu device, and then iOS, 226 226 00:09:40,900 --> 00:09:42,950 and then choose your favorite device here. 227 227 00:09:42,950 --> 00:09:44,960 And now with that up and running, 228 228 00:09:44,960 --> 00:09:46,100 what you can do is, 229 229 00:09:46,100 --> 00:09:48,280 you can start your Flutter app. 230 230 00:09:48,280 --> 00:09:51,740 By running Flutter run in the command prompt. 231 231 00:09:51,740 --> 00:09:55,670 Now for that, we need a Flutter app though, right. 232 232 00:09:55,670 --> 00:09:57,940 Because right now we only install Flutter, 233 233 00:09:57,940 --> 00:10:01,100 but we haven't set up a Flutter app, a new project. 234 234 00:10:01,100 --> 00:10:02,290 So let's quickly do that. 235 235 00:10:02,290 --> 00:10:03,123 And for that, 236 236 00:10:03,123 --> 00:10:05,610 you should first of all navigate into the folder, 237 237 00:10:05,610 --> 00:10:08,010 where you want to create your Flutter app. 238 238 00:10:08,010 --> 00:10:10,360 Once you navigated into that folder, 239 239 00:10:10,360 --> 00:10:12,770 where you want to create your new Flutter project. 240 240 00:10:12,770 --> 00:10:15,570 Run, Flutter, create, and then the name. 241 241 00:10:15,570 --> 00:10:17,920 For example, first underscore app. 242 242 00:10:17,920 --> 00:10:20,730 Important, this project name must 243 243 00:10:20,730 --> 00:10:23,210 not contain dashes or white spaces. 244 244 00:10:23,210 --> 00:10:25,750 It should be using underscores instead, 245 245 00:10:25,750 --> 00:10:28,290 or it will be one word only. 246 246 00:10:28,290 --> 00:10:31,610 Hit enter, and this will now set up a new Flutter project 247 247 00:10:31,610 --> 00:10:33,810 in that specified location. 248 248 00:10:33,810 --> 00:10:37,370 A new sub folder which holds that project to be precise. 249 249 00:10:37,370 --> 00:10:38,853 Can take a couple of seconds. 250 250 00:10:40,400 --> 00:10:41,670 And once it's done, 251 251 00:10:41,670 --> 00:10:44,460 you can navigate into this newly created folder. 252 252 00:10:44,460 --> 00:10:46,920 In my case, it's named first underscore app. 253 253 00:10:46,920 --> 00:10:49,510 And then hit Flutter run. 254 254 00:10:49,510 --> 00:10:50,870 Enter this, hit enter. 255 255 00:10:50,870 --> 00:10:53,770 And with the iOS simulator up and running, 256 256 00:10:53,770 --> 00:10:56,390 you should be able to see that Flutter app 257 257 00:10:56,390 --> 00:11:00,130 on that iOS simulator momentarily. 258 258 00:11:00,130 --> 00:11:02,980 The first build or the first time you run this, 259 259 00:11:02,980 --> 00:11:05,720 can take a couple of seconds longer, by the way. 260 260 00:11:05,720 --> 00:11:06,553 Here we are. 261 261 00:11:06,553 --> 00:11:09,140 Now important, keep that process running, 262 262 00:11:09,140 --> 00:11:09,973 don't quit it. 263 263 00:11:09,973 --> 00:11:12,250 You could quit it with Ctrl + C, 264 264 00:11:12,250 --> 00:11:13,920 but you wanna keep that running, 265 265 00:11:13,920 --> 00:11:16,880 so that you can always rebuild your project, 266 266 00:11:16,880 --> 00:11:19,660 and instantly ship that new version to the device. 267 267 00:11:19,660 --> 00:11:22,490 Whenever you change something in your code. 268 268 00:11:22,490 --> 00:11:25,500 So with that, you should see this. 269 269 00:11:25,500 --> 00:11:28,900 Your first Flutter app running on the iPhone. 270 270 00:11:28,900 --> 00:11:30,880 And you can hit that plus button, 271 271 00:11:30,880 --> 00:11:33,380 to see a counter that is incremented. 272 272 00:11:33,380 --> 00:11:36,230 This is an app the Flutter tool created for you. 273 273 00:11:36,230 --> 00:11:39,260 We of course didn't write any code yet. 274 274 00:11:39,260 --> 00:11:40,093 Now that's cool. 275 275 00:11:40,093 --> 00:11:42,370 And we will actually edit this a little bit, 276 276 00:11:42,370 --> 00:11:43,990 to see how we can well, 277 277 00:11:43,990 --> 00:11:46,160 work with that first Flutter app. 278 278 00:11:46,160 --> 00:11:49,880 But obviously, we also wanna build for Android, right. 279 279 00:11:49,880 --> 00:11:52,390 So let's go back to these installation docs. 280 280 00:11:52,390 --> 00:11:54,540 We're done with the iOS setup here, 281 281 00:11:54,540 --> 00:11:55,870 the simulator at least. 282 282 00:11:55,870 --> 00:11:59,110 Now if you wanna deploy to a real iOS device, 283 283 00:11:59,110 --> 00:12:02,390 you can follow these steps here. 284 284 00:12:02,390 --> 00:12:06,270 You will essentially need to plug in your real iPhone. 285 285 00:12:06,270 --> 00:12:07,580 Then also again, 286 286 00:12:07,580 --> 00:12:09,780 execute these steps to install Homebrew, 287 287 00:12:09,780 --> 00:12:12,070 and then these extra tools which you need, 288 288 00:12:12,070 --> 00:12:16,600 to be able to ship your app to a real iPhone. 289 289 00:12:16,600 --> 00:12:18,120 And once you're done with that, 290 290 00:12:18,120 --> 00:12:20,250 you can continue with these steps. 291 291 00:12:20,250 --> 00:12:23,720 And you will need to do some tweaking in Xcode, 292 292 00:12:23,720 --> 00:12:26,880 to be able to ship your app to your real device. 293 293 00:12:26,880 --> 00:12:28,710 Now, that is something I'll come back 294 294 00:12:28,710 --> 00:12:30,930 to later in this course. 295 295 00:12:30,930 --> 00:12:34,460 When we will actually test this on a real device, 296 296 00:12:34,460 --> 00:12:36,830 and also deploy the app at the end. 297 297 00:12:36,830 --> 00:12:39,440 But again, feel free to already go through these steps. 298 298 00:12:39,440 --> 00:12:40,650 They're really simple, 299 299 00:12:40,650 --> 00:12:43,120 if you wanna run this on a real device. 300 300 00:12:43,120 --> 00:12:45,720 Now I'll move on to Android for now. 301 301 00:12:45,720 --> 00:12:48,730 And for that we will need Android Studio. 302 302 00:12:48,730 --> 00:12:51,580 Just like Xcode is the official IDE, 303 303 00:12:51,580 --> 00:12:54,710 and contains all the build tools for iOS apps. 304 304 00:12:54,710 --> 00:12:57,550 Android Studio is the same for Android. 305 305 00:12:57,550 --> 00:13:00,270 So click that link to be forwarded 306 306 00:13:00,270 --> 00:13:02,940 to the download page of Android Studio. 307 307 00:13:02,940 --> 00:13:04,010 And on that page, 308 308 00:13:04,010 --> 00:13:07,990 it should automatically present to you the Mac OS download. 309 309 00:13:07,990 --> 00:13:10,940 So you can simply hit download Android Studio here. 310 310 00:13:10,940 --> 00:13:14,870 Accept these license agreements and well then download. 311 311 00:13:14,870 --> 00:13:18,120 Store this in any folder of your choice. 312 312 00:13:18,120 --> 00:13:21,430 And this again, is a little bit of a bigger file. 313 313 00:13:21,430 --> 00:13:24,683 So let's wait for this to finish before we continue. 314 314 00:13:25,670 --> 00:13:27,470 Now the download did finish. 315 315 00:13:27,470 --> 00:13:29,530 You can then simply execute that file, 316 316 00:13:29,530 --> 00:13:32,050 and it will launch an installer for you. 317 317 00:13:32,050 --> 00:13:34,893 But we also close the iOS simulator here. 318 318 00:13:36,610 --> 00:13:38,640 Now that Android Studio installer 319 319 00:13:38,640 --> 00:13:40,690 is pretty straightforward on Mac. 320 320 00:13:40,690 --> 00:13:43,343 Just drag that into that applications folder. 321 321 00:13:45,050 --> 00:13:49,320 And this will copy or install that tool in that folder, 322 322 00:13:49,320 --> 00:13:51,580 which again will take a couple of seconds, 323 323 00:13:51,580 --> 00:13:54,500 since it also unpacks that folder. 324 324 00:13:54,500 --> 00:13:56,550 And once you're done with that, 325 325 00:13:56,550 --> 00:13:59,990 let's go back to the Flutter installation page. 326 326 00:13:59,990 --> 00:14:01,810 Once you're done with that, 327 327 00:14:01,810 --> 00:14:04,040 you need to start Android Studio, 328 328 00:14:04,040 --> 00:14:05,920 and go through the setup wizard 329 329 00:14:05,920 --> 00:14:09,180 to configure everything and install everything you need. 330 330 00:14:09,180 --> 00:14:11,650 Now you could also be getting a security warning, 331 331 00:14:11,650 --> 00:14:14,210 that the opening of Android Studio was blocked, 332 332 00:14:14,210 --> 00:14:15,393 because it was from, 333 333 00:14:16,860 --> 00:14:17,693 well, from the internet, 334 334 00:14:17,693 --> 00:14:19,920 not from an identified developer. 335 335 00:14:19,920 --> 00:14:22,020 You can then open it anyways through 336 336 00:14:22,020 --> 00:14:23,973 the Mac security and privacy settings. 337 337 00:14:25,970 --> 00:14:29,280 And ultimately, this should bring up this setup wizard. 338 338 00:14:29,280 --> 00:14:31,280 Now click next on the first screen, 339 339 00:14:31,280 --> 00:14:34,230 click custom on the next screen. 340 340 00:14:34,230 --> 00:14:37,940 Next again, now here you can choose your editor theme, 341 341 00:14:37,940 --> 00:14:40,110 if you wanna have the light or the dark one. 342 342 00:14:40,110 --> 00:14:42,500 You don't need to use Android Studio 343 343 00:14:42,500 --> 00:14:44,350 as an editor for this course. 344 344 00:14:44,350 --> 00:14:45,860 And actually I won't, 345 345 00:14:45,860 --> 00:14:48,770 but you can, so I'll go with dark color here. 346 346 00:14:48,770 --> 00:14:50,680 But that is totally up to you. 347 347 00:14:50,680 --> 00:14:51,610 Now on the next screen, 348 348 00:14:51,610 --> 00:14:55,040 make sure to also check Android Virtual Device here, 349 349 00:14:55,040 --> 00:14:56,723 under the installation options. 350 350 00:14:57,740 --> 00:15:00,310 The default installation path then should be all right. 351 351 00:15:00,310 --> 00:15:02,430 Click next, and finish. 352 352 00:15:02,430 --> 00:15:05,340 And now this will download a bunch of things, 353 353 00:15:05,340 --> 00:15:08,500 and install all the SDKs and tools, 354 354 00:15:08,500 --> 00:15:10,950 you need to develop Android apps. 355 355 00:15:10,950 --> 00:15:13,990 And these will be used behind the scenes by Flutter, 356 356 00:15:13,990 --> 00:15:15,740 which is why we need them. 357 357 00:15:15,740 --> 00:15:19,800 So let me fast forward until this is also done. 358 358 00:15:19,800 --> 00:15:22,230 Now, by the way, this take a couple of minutes, 359 359 00:15:22,230 --> 00:15:24,310 so don't worry if it takes a bit longer. 360 360 00:15:24,310 --> 00:15:27,083 It downloads and installs quite a lot of things. 361 361 00:15:28,010 --> 00:15:29,760 Now the set up finished for me here. 362 362 00:15:29,760 --> 00:15:31,890 So let's click finish. 363 363 00:15:31,890 --> 00:15:33,930 And thereafter, you can click on open 364 364 00:15:33,930 --> 00:15:36,443 an existing Android Studio project. 365 365 00:15:37,550 --> 00:15:40,160 Now there simply navigate to the folder, 366 366 00:15:40,160 --> 00:15:43,530 where you just created your new Flutter app. 367 367 00:15:43,530 --> 00:15:47,290 In my case, that's that first underscore app folder. 368 368 00:15:47,290 --> 00:15:49,693 Select a whole folder and click open. 369 369 00:15:50,610 --> 00:15:52,830 And this will bring up Android Studio 370 370 00:15:52,830 --> 00:15:54,850 with that project open. 371 371 00:15:54,850 --> 00:15:57,340 Now when you open it for the first time, 372 372 00:15:57,340 --> 00:15:59,720 it will actually scan that folder. 373 373 00:15:59,720 --> 00:16:02,550 So let's wait for this to finish. 374 374 00:16:02,550 --> 00:16:05,220 And it should actually suggest to you two things. 375 375 00:16:05,220 --> 00:16:08,400 Down there, it finds something about a plugin. 376 376 00:16:08,400 --> 00:16:10,030 And there, you can simply expand this, 377 377 00:16:10,030 --> 00:16:12,260 and click on configure plugins. 378 378 00:16:12,260 --> 00:16:15,090 It actually also shows you something about the Dart files, 379 379 00:16:15,090 --> 00:16:16,740 we ignore this for now. 380 380 00:16:16,740 --> 00:16:20,600 So now choose that Flutter plugin and click Okay. 381 381 00:16:20,600 --> 00:16:22,430 And thereafter click yes, 382 382 00:16:22,430 --> 00:16:24,520 to also install that Dart plugin 383 383 00:16:24,520 --> 00:16:26,223 for which it's asking up there. 384 384 00:16:30,840 --> 00:16:33,560 Thereafter, simply restart. 385 385 00:16:33,560 --> 00:16:35,070 Now once you restarted, 386 386 00:16:35,070 --> 00:16:38,680 you may get a message at the bottom here, 387 387 00:16:38,680 --> 00:16:40,250 regarding IDE and plugin updates. 388 388 00:16:40,250 --> 00:16:41,450 If you don't, that's fine too. 389 389 00:16:41,450 --> 00:16:43,290 In my case, I do get one. 390 390 00:16:43,290 --> 00:16:45,210 So I'll simply update now, 391 391 00:16:45,210 --> 00:16:47,790 to install the latest versions of all the SDKs, 392 392 00:16:47,790 --> 00:16:48,960 and build tools I might need. 393 393 00:16:48,960 --> 00:16:51,250 And that again, will get downloaded. 394 394 00:16:51,250 --> 00:16:54,150 Which again, will take a couple of seconds. 395 395 00:16:54,150 --> 00:16:55,480 And now with all that done, 396 396 00:16:55,480 --> 00:16:56,913 let me click finish here. 397 397 00:16:58,125 --> 00:17:00,020 And now this is our Flutter project. 398 398 00:17:00,020 --> 00:17:02,220 Now I will open this in a different IDE, 399 399 00:17:02,220 --> 00:17:04,070 where it's also a bit easier to read. 400 400 00:17:04,070 --> 00:17:07,630 In a second, for now we won't work on that code here. 401 401 00:17:07,630 --> 00:17:11,110 Instead, let's run this on an emulator. 402 402 00:17:11,110 --> 00:17:14,110 For that, we can simply go to tools, 403 403 00:17:14,110 --> 00:17:15,710 and then AVD Manager. 404 404 00:17:15,710 --> 00:17:18,393 That stands for Android Virtual Device. 405 405 00:17:19,250 --> 00:17:20,690 Let's open that tool. 406 406 00:17:20,690 --> 00:17:24,140 And here I actually got some pre-configured devices. 407 407 00:17:24,140 --> 00:17:26,090 You should at least have one, 408 408 00:17:26,090 --> 00:17:28,640 that Nexus or some other device, 409 409 00:17:28,640 --> 00:17:30,750 which is created with the installation. 410 410 00:17:30,750 --> 00:17:32,980 You can always create a new virtual device, 411 411 00:17:32,980 --> 00:17:35,570 by clicking that button here at the bottom. 412 412 00:17:35,570 --> 00:17:38,700 And then you can choose which device you wanna use. 413 413 00:17:38,700 --> 00:17:40,870 Let's say the Pixel two. 414 414 00:17:40,870 --> 00:17:43,260 Continue, choose your API version. 415 415 00:17:43,260 --> 00:17:46,460 Now typically, the highest one is a good choice, 416 416 00:17:46,460 --> 00:17:48,920 or the one selected by default I should say. 417 417 00:17:48,920 --> 00:17:52,300 Not necessarily the cutting edge one, but this one. 418 418 00:17:52,300 --> 00:17:53,900 Click next again. 419 419 00:17:53,900 --> 00:17:57,060 Now here on emulator performance, 420 420 00:17:57,060 --> 00:18:00,340 you should choose the hardware emulation 421 421 00:18:00,340 --> 00:18:03,420 for a faster emulator. 422 422 00:18:03,420 --> 00:18:05,650 The other settings should be fine. 423 423 00:18:05,650 --> 00:18:07,330 Simply hit finish. 424 424 00:18:07,330 --> 00:18:09,750 And this should create that new emulator. 425 425 00:18:09,750 --> 00:18:10,880 And you can then start it, 426 426 00:18:10,880 --> 00:18:14,590 by clicking on that play button on the very right here. 427 427 00:18:14,590 --> 00:18:17,960 Now this will bring up your Android emulator. 428 428 00:18:17,960 --> 00:18:20,070 Now we can of course use that emulator, 429 429 00:18:20,070 --> 00:18:22,790 to run our Flutter app there too. 430 430 00:18:22,790 --> 00:18:24,640 And to run it, what we need to do, 431 431 00:18:24,640 --> 00:18:26,940 is we need to go back to that command line. 432 432 00:18:26,940 --> 00:18:30,120 Where we previously already ran it on the iPhone. 433 433 00:18:30,120 --> 00:18:33,190 And repeat that Flutter run command. 434 434 00:18:33,190 --> 00:18:35,150 If you still got the old one running, 435 435 00:18:35,150 --> 00:18:36,540 which you probably don't have 436 436 00:18:36,540 --> 00:18:38,520 if you shut down the old simulator. 437 437 00:18:38,520 --> 00:18:42,720 You can always quits the running process with Ctrl + C. 438 438 00:18:42,720 --> 00:18:44,080 So let's hit Flutter run, 439 439 00:18:44,080 --> 00:18:46,420 to run it on our Android emulator, 440 440 00:18:46,420 --> 00:18:49,040 once that emulator did boot up. 441 441 00:18:49,040 --> 00:18:50,870 And it will build the project 442 442 00:18:50,870 --> 00:18:53,020 with the help of the Android SDK, 443 443 00:18:53,020 --> 00:18:56,180 that was installed together with Android Studio. 444 444 00:18:56,180 --> 00:18:58,070 And that first build process, 445 445 00:18:58,070 --> 00:19:00,300 can again take a couple of seconds. 446 446 00:19:00,300 --> 00:19:02,890 Subsequent ones will be faster. 447 447 00:19:02,890 --> 00:19:04,500 And now it should be up and running. 448 448 00:19:04,500 --> 00:19:06,380 Let's view it, and there it is. 449 449 00:19:06,380 --> 00:19:07,650 This is our device, 450 450 00:19:07,650 --> 00:19:09,150 and this is our Flutter app. 451 451 00:19:09,150 --> 00:19:12,440 And we can click the plus button to increment this counter. 452 452 00:19:12,440 --> 00:19:13,520 Awesome. 453 453 00:19:13,520 --> 00:19:16,170 So this is how we install Flutter, 454 454 00:19:16,170 --> 00:19:19,680 and run it on both the iOS and Android emulators. 455 455 00:19:19,680 --> 00:19:21,630 Now if you wanna run it on real devices, 456 456 00:19:21,630 --> 00:19:24,520 you can follow the steps outlined in the documentation. 457 457 00:19:24,520 --> 00:19:25,353 But of course, 458 458 00:19:25,353 --> 00:19:27,660 we'll also run it together on the real device 459 459 00:19:27,660 --> 00:19:29,370 later in this course. 460 460 00:19:29,370 --> 00:19:31,640 For now, let's focus on the editor, 461 461 00:19:31,640 --> 00:19:33,840 with which we're going to work on this code. 39547
