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 run.
