Unable to alert testing users for a new version of the Internal Testing Version

[kndrckjvr]

I wanted to test out the alert dialog for our Internal Testing Users and wanted to use the AppCast Sample file to trigger the update. but testing out in my test device first as we just started using it, since the current version of testing application is 1.0.4, I needed to release a 2.0.0 or something like that, for this one I have used the testappcast.xml in this repository but it is not triggering the dialog.

This is my main method.

void main() async {
  WidgetsFlutterBinding.ensureInitialized();

  await Upgrader.clearSavedSettings();

  runApp(const MyApp());
}

This is the sample implementation in our Stateful Widget.

  static const appcastURL =
      'https://raw.githubusercontent.com/larryaasen/upgrader/master/test/testappcast.xml';
  final upgrader = Upgrader(
    storeController: UpgraderStoreController(
      onAndroid: () => UpgraderAppcastStore(appcastURL: appcastURL),
    ),
  );

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
        home: UpgradeAlert(
      upgrader: upgrader,
      ),
      child: Scaffold(...),
     );
  }
