All language subtitles for 003 App Overview_en

In the last section, we spoke a little bit about how we create flutter applications, so remember,

you and I are going to be creating a bunch of widgets and then we assemble them together to get our

desired application.

In general, there's a tremendous number of widgets included with Flutter that we can leverage to build

some really interesting applications quite quickly in this section where will continue by talking about

the first application we're going to be putting together.

So let's take a look at a mockup.

OK, so here's the general idea.

We're going to build an application that will show a list of images to our users.

When a user first puts up our application, we'll show them the screen over here at the left hand side.

So by default, nothing is displayed on the screen.

There's going to be a button at the bottom right hand side, and if a user presses on this thing, then

we will show a single image to the user, like what you see here in the middle.

We'll show the image and then right underneath it will show some relevant title for the image as well.

If a user then presses on this button again, we're going to add another image to that list and then

for however many times the user presses this button, we're going to add an additional image each and

every time.

So along the process, we're going to learn quite a bit about handling images.

We're going to learn about building lists.

And we're also going to learn a little bit about fetching data off the Internet, because the list of

images that we're going to display here are not going to be saved on our hard drive or anything like

that.

We're going to instead fetch a list of images off the Internet.

And then every time user presses a button will show an additional image that we have fetched.

OK, so that's the general idea.

There's definitely going to be a good set of challenges inside of here.

So let's continue.

But before we do, let's make sure that we start up our emulator and make sure that we're all ready

to start working on this application.

So I'm going to make sure that I'm inside of my PIC's directory, which is the name of the project which

is generated.

And then inside this, I'm going to run, flutter, run like so.

And then I should see my application appear inside my emulator very shortly.

All right, so I'm going to let that do a start up and we'll come back to the next section and we'll

talk about how we're going to build this application.
