Here's my code :

main.dart

Future<void> main() async {
  WidgetsFlutterBinding();
  await Hive.initFlutter();
  if (!Hive.isAdapterRegistered(AddEventModelAdapter().typeId)) {
    Hive.registerAdapter(AddEventModelAdapter());
  }
  AwesomeNotifications()
      .initialize('resource://drawable/res_notification_app_icon', [
    NotificationChannel(
      channelKey: 'schedule_channel',
      channelName: 'scheduled_channel',
      channelDescription: 'descroiption',
      locked: true,
      importance: NotificationImportance.High,
    ),
  ]);

  runApp(const MyApp());
}

Whenever you add a plugin in your pubspec.yaml, you need to stop the app and re-run it again because the plugin contains native code on both platforms.

If it still does not work, then do flutter clean and then flutter run.
