@SebastianEngel Could you share an example how to call the init() method? Thank you

Future main() async {
  PushNotificationsManager().init(); <--

That's the way I do it.

Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();
  PushNotificationsManager().init();
  runApp(MyApp());
}

final FirebaseMessaging _firebaseMessaging = FirebaseMessaging();

_firebaseMessaging.requestNotificationPermissions();
_firebaseMessaging.configure();

These method calls not exist in latest flutter_message version.

firebase_messaging: ^10.0.5

Some replacements are needed:

final FirebaseMessaging _firebaseMessaging = FirebaseMessaging.instance;

and

      _firebaseMessaging.requestPermission();
      // _firebaseMessaging.configure(); -> configure() has been removed

See: https://firebase.flutter.dev/docs/migration/#messaging
