Run the app

Locate the main Android Studio toolbar:

In the target selector, select an Android device for running the app.
If none are listed as available,
select Tools > AVD Manager and create one there.
For details, see Managing AVDs.

Click the run icon in the toolbar, or invoke the menu item Run > Run.

After the app build completes, you’ll see the starter app on your device.

Flutter offers a fast development cycle with Stateful Hot Reload,

restarting or losing app state.
Make a change to app source,
tell your IDE or command-line tool that you want to hot reload,
and see the change in your simulator, emulator, or device.

Open lib/main.dart.

Change the string
