Its very easy way to inform users to install the new version from the respective platform. For that “upgrader” can be used for that. User will see the update alert like the above image:

You have to add its function: UpgradeAlert() into the MaterialApp home like the below example by providing required widgets.


import 'package:upgrader/upgrader.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await UpgradeManager.initialize();
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: UpgradeAlert(
        dialogStyle: UpgradeDialogStyle.cupertino,
        child: HomeScreen(),
      ),
    );
  }
}

Before making the release build you can test it by downgrading the version in pubspec.yml and then create a build and test it.
