如何从 main() 的开头重新启动 Flutter 应用程序？

Question

I want to restart my app at some point from the beginning of the main() function and not just rebuild the whole widget tree.

Here is an example of my code, the thing is I want to call init() when restart

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await init();
  runApp(
    const MyApp(),
  );
}

I have tried to wrap the widget tree with a Restart widget and tried phoenix package

But both of them just rebuild the widget tree regardless of what is above in main(). I even tried to call the main() directly but it didn't work as expected.

Is there any solution for this case?

Answer 1

I think you can try "Restart App" module

1. Instal from your teminal:

flutter pub add restart_app

2. Import from your dart file:

import 'package:restart_app/restart_app.dart';

3. Call "Restart App" from main():

onPressed: () { Restart.restartApp();}

Have a nice day...

Answer 2

You runApp(YourApp()) again where you want to restart. 1
