I have a setting screen, when I change FontFamily it needs to restart the app to change all app fonts, And it restarts after the app closed, but I want to restart the app with a button instead of closing the app. does there any way to do this ?

The best solution... using "Restart App" module

  1. Instal from your teminal:

flutter pub add restart_app

  1. Import from your dart file:

import 'package:restart_app/restart_app.dart';

  1. Call "Restart App" from your Button:

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

Have a nice day...

Use this package https://pub.dev/packages/flutter_phoenix and call Phoenix.rebirth(context); when you want to reload the app

I have implemented the https://pub.dev/packages/flutter_phoenix package in my app, to restart the app wrap widget with Phoenix on the line of code:

runApp(Phoenix(child: MyApp()))

wherever you want to restart the app just implement this line of code

Phoenix.rebirth(context);

hope this help
