Would you like to inspect the original subtitles? These are the user uploaded subtitles that are being translated: 1 00:00:02,310 --> 00:00:05,890 So we've got quite a lot of folders and files here. Now 2 00:00:05,920 --> 00:00:12,550 a lot of the files you see here are only there for configuration and a lot of the folders here also 3 00:00:12,550 --> 00:00:14,090 don't need to be touched by you 4 00:00:14,110 --> 00:00:17,170 but let me explain what each folder and file does. 5 00:00:17,170 --> 00:00:19,420 Let's go from top to bottom, 6 00:00:19,540 --> 00:00:24,730 the idea folder here holds some configuration for Android Studio. 7 00:00:24,730 --> 00:00:29,860 It doesn't really matter for us here because we're not working with Android Studio and you don't need 8 00:00:29,860 --> 00:00:31,770 to change anything in here. 9 00:00:31,980 --> 00:00:34,320 Vscode is a folder you might not have, 10 00:00:34,330 --> 00:00:39,120 I have it here because I added some extra configuration for this project, 11 00:00:39,160 --> 00:00:45,160 I set the zoom level so that you can see my code and anything you do configure for your vscode, 12 00:00:45,220 --> 00:00:50,650 your Visual Studio Code project here would end up in such a config file and you don't need that if 13 00:00:50,650 --> 00:00:54,130 you don't have any special development options here. 14 00:00:54,130 --> 00:00:56,140 The Android folder is super important, 15 00:00:56,170 --> 00:01:01,900 it holds a complete Android project as you could also create it without Flutter. 16 00:01:01,900 --> 00:01:02,800 This is is in the end 17 00:01:02,800 --> 00:01:10,780 the project which the Flutter SDK will use to kind of merge with your Flutter code you could say, so 18 00:01:10,780 --> 00:01:16,180 when your Flutter code gets compiled to native code, it will basically get injected into this Android 19 00:01:16,180 --> 00:01:17,710 project you could say 20 00:01:17,710 --> 00:01:23,890 and that is the Android project which later will be built into a real Android app or later actually 21 00:01:23,890 --> 00:01:28,330 is the wrong word, which already got built into this Android app we're seeing here. 22 00:01:28,330 --> 00:01:33,520 So this is in the end of normal Android project with your compiled Flutter code and you don't need to change 23 00:01:33,610 --> 00:01:39,460 anything in here or very rarely and I will mention when you do need to change anything here. For the 24 00:01:39,460 --> 00:01:41,410 most part, for the most time, 25 00:01:41,530 --> 00:01:47,140 this is a passive folder which will be used by Flutter and therefore it's super important but not a 26 00:01:47,140 --> 00:01:52,570 folder you work on. The build folder is also very important, in the end, 27 00:01:52,630 --> 00:01:56,960 this holds the output of your Flutter application, 28 00:01:56,980 --> 00:02:04,120 in this case here also some Android or Java files and this folder is generated and managed by the Flutter 29 00:02:04,120 --> 00:02:05,080 SDK. 30 00:02:05,080 --> 00:02:11,470 You shouldn't change anything in there, that will all be done automatically by the Flutter SDK when you 31 00:02:11,470 --> 00:02:16,910 are developing or when you are building your app for deployment, which we will do at the end of the course 32 00:02:17,050 --> 00:02:23,780 and therefore this is also a passive folder. So thus far, no folder in which we would work. 33 00:02:23,860 --> 00:02:25,670 It's the same for the iOS folder, 34 00:02:25,750 --> 00:02:31,720 we had the Android folder with a full Android project, which is important for building an Android project, 35 00:02:31,810 --> 00:02:37,570 both for development and for production and the iOS folder is simply the same for 36 00:02:37,730 --> 00:02:44,260 iOS projects. Now on Windows, you won't have that folder because on Windows unfortunately, you can't 37 00:02:44,260 --> 00:02:46,150 build iOS applications, 38 00:02:46,300 --> 00:02:53,830 that's not allowed by Apple. On MacOS, you will have it and this holds a normal Xcode project, Xcode 39 00:02:53,860 --> 00:02:59,800 is the development environment of MacOS, for iOS apps and just as with the Android folder, 40 00:02:59,800 --> 00:03:04,310 this is a folder where you really won't work in too much. 41 00:03:04,330 --> 00:03:08,650 There are some occasions where we will do some work in here but I will mention when this is the case, 42 00:03:08,860 --> 00:03:15,220 for the most part this is a passive folder which gets kind of merged with your Flutter code in the end 43 00:03:15,610 --> 00:03:22,510 and which will all be managed by the Flutter SDK to get iOS applications, both for development and 44 00:03:22,510 --> 00:03:30,160 testing as well as for the real application in the end which you deploy. The lib folder is now the important 45 00:03:30,160 --> 00:03:37,690 folder for us, lib stands for library and that is the folder where we will do 99% of our work. 46 00:03:37,690 --> 00:03:44,320 It is the folder where we will add all our Dart files, Dart is the programming language Flutter uses 47 00:03:44,740 --> 00:03:47,800 to write the code for our Flutter application. 48 00:03:47,800 --> 00:03:52,370 So this is the folder where we will add files and where we will write code in, 49 00:03:52,390 --> 00:03:58,640 this is a super important folder for us. The test folder is a folder which won't be too important for 50 00:03:58,640 --> 00:03:59,340 us here, 51 00:03:59,360 --> 00:04:03,900 it allows us to write tests for our application, automated tests, 52 00:04:04,040 --> 00:04:09,230 so basically code that runs our code and tests it for certain things, 53 00:04:09,380 --> 00:04:15,140 certainly important once you're a bit of a more advanced Dart and Flutter developer but not important 54 00:04:15,140 --> 00:04:21,690 for us right now and therefore, we can safely ignore this. gitignore is a folder that helps you when you're 55 00:04:21,710 --> 00:04:25,940 using git which is a source code management tool, 56 00:04:25,940 --> 00:04:31,070 it allows you to create snapshots of your code, save them and you can go back to them at a later point 57 00:04:31,070 --> 00:04:31,510 of time 58 00:04:31,520 --> 00:04:39,380 if you messed up something or if you wanna change something. It is not a tool you have to use but often 59 00:04:39,410 --> 00:04:42,260 during development, git can be really useful 60 00:04:42,260 --> 00:04:48,920 and after this lecture, you find a short text lecture on git. Using it is totally optional but if you 61 00:04:48,920 --> 00:04:53,870 want to use it, if that sounds interesting to you, that lecture will help you get started with it and then 62 00:04:53,870 --> 00:04:55,720 you can use it if you want to use it. 63 00:04:56,720 --> 00:05:03,920 The metadata file is not really a file we will work on, it will be managed automatically by Flutter 64 00:05:04,040 --> 00:05:10,670 and in the end, the Flutter tool simply saves some information in here which it needs to build 65 00:05:10,670 --> 00:05:12,010 our application correctly 66 00:05:12,020 --> 00:05:13,330 and so on. 67 00:05:13,340 --> 00:05:15,720 The same is true for the .packages file, 68 00:05:15,730 --> 00:05:18,170 it's not a file we'll do any work in, 69 00:05:18,240 --> 00:05:21,900 this is generated automatically by the Flutter SDK and in the end, 70 00:05:21,890 --> 00:05:24,920 this also just manages some internal dependencies, 71 00:05:24,920 --> 00:05:26,330 some packages 72 00:05:26,360 --> 00:05:29,860 this project needs and it is fully managed automatically, 73 00:05:29,870 --> 00:05:35,320 you should not delete it but you also shouldn't work in it. This file here, 74 00:05:35,330 --> 00:05:35,760 this .iml 75 00:05:35,790 --> 00:05:41,740 file which has your project name as a name is also file where we will not work in, 76 00:05:41,740 --> 00:05:47,550 it's also managed automatically by the Flutter SDK to again manage some internal dependencies and some 77 00:05:48,000 --> 00:05:49,290 settings for this project 78 00:05:49,290 --> 00:05:55,940 you could say and it's not a file which we'll change. Now the pubspec.lock file is also not a file 79 00:05:55,940 --> 00:06:01,440 we'll work in and it becomes clearer once we understand the pubspec.yaml file which is a file in 80 00:06:01,440 --> 00:06:02,980 which we will work. 81 00:06:03,000 --> 00:06:09,620 This is a file that allows you to mostly manage these dependencies of your project. 82 00:06:09,630 --> 00:06:11,090 Now what does this mean? 83 00:06:11,100 --> 00:06:15,950 This means that here, you can configure which other third-party packages 84 00:06:16,020 --> 00:06:18,220 your project might be using. 85 00:06:18,420 --> 00:06:24,720 You can also configure some other things in here, like for example fonts you want to use or images you 86 00:06:24,720 --> 00:06:29,880 want to use in your application and we'll use all these features, we'll work with third-party packages 87 00:06:30,030 --> 00:06:36,060 and we'll use fonts and images and therefore I will show you how to work with this file and how to change 88 00:06:36,060 --> 00:06:38,790 it to include new fonts or new images, 89 00:06:39,060 --> 00:06:41,850 I will show you all of that step-by-step. 90 00:06:41,850 --> 00:06:49,110 Basically what you have here is code written in yaml which is a certain format for structuring text 91 00:06:49,110 --> 00:06:54,480 files, where you use indentation to express how code works together 92 00:06:54,570 --> 00:07:01,350 and here for example, we're right now specifying with which Dart version this works, which version 93 00:07:01,350 --> 00:07:07,200 or application it should have, also which third-party packages we might be using, like here the Cupertino 94 00:07:07,200 --> 00:07:13,160 icons which allows us to use certain iOS styled icons in the application and 95 00:07:13,210 --> 00:07:16,740 we'll add other third-party packages throughout this course here. 96 00:07:16,740 --> 00:07:26,010 So this is basically a config file that allows us to configure how our application works or which external 97 00:07:26,010 --> 00:07:29,900 dependencies it has, for the moment we don't need to change anything here. 98 00:07:29,940 --> 00:07:35,970 The pubspec.lock file in the end is a file that is generated automatically based on your 99 00:07:36,000 --> 00:07:37,380 .yaml file here 100 00:07:37,560 --> 00:07:44,880 and this simply holds more details then about all the dependencies you have and it is required by Flutter 101 00:07:44,910 --> 00:07:47,630 but it's not a file you will work, in the end 102 00:07:47,670 --> 00:07:49,830 as I said, it will be generated automatically, 103 00:07:49,830 --> 00:07:51,800 we will only work in the yaml file. 104 00:07:52,290 --> 00:07:57,900 Well and the README file is an automatically generated README file which we can ignore, it holds some 105 00:07:58,140 --> 00:08:01,170 information about our project and you could change this here 106 00:08:01,170 --> 00:08:06,450 if you were sharing your project with other developers and you want to give them some information. So 107 00:08:06,450 --> 00:08:11,520 that was a thorough walkthrough through all the folders and files, the core takeaway is that we will work in 108 00:08:11,520 --> 00:08:17,730 the lib folder and sometimes with that pubspec.yaml file and we can basically ignore all other files 109 00:08:17,790 --> 00:08:18,420 and folders. 11887
