Change background color used in Recents apps screen with Flutter app

Question

How can I change the color shown in the app switcher of Android. Right now the color comes up with a gray background, but I want it to be red.

This is the app code.

import 'package:flutter/material.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      color: Colors.red,
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: Material(
        child: Text('Check color in app switcher.'),
      ),
    );
  }
}

The color parameter of MaterialApp has no effect.

Answer 1

If you are using the MaterialApp you would use the color attribute to change the color of the app bar in the switcher.

You could also use the SystemChrome.setApplicationSwitcherDescription method which you would find in package:flutter/services.dart
