[firebase messaging] Unable to receive flutter notification in ios with firebase and flutter local notification <12

[jesussmile]

Hi the plugin i am using are firebase_messaging: ^14.1.2 and flutter_local_notifications: ^12.0.4

Firstly it works fine with android however in ios i have no notification,
I set up my AppDelegate.swift as follows

import UIKit
import Flutter
import background_locator_2
import flutter_local_notifications


func registerPlugins(registry: FlutterPluginRegistry) -> () {
    if (!registry.hasPlugin("BackgroundLocatorPlugin")) {
        GeneratedPluginRegistrant.register(with: registry)
    }
}

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) -> Bool {
    GeneratedPluginRegistrant.register(with: self)
    BackgroundLocatorPlugin.setPluginRegistrantCallback(registerPlugins)
     if #available(iOS 10.0, *) {
      UNUserNotificationCenter.current().delegate = self as UNUserNotificationCenterDelegate
    }
    return super.application(application, didFinishLaunchingWithOptions: launchOptions)
  }
}

nextly in my main.dart

final FlutterLocalNotificationsPlugin notificationsPlugin =
    FlutterLocalNotificationsPlugin();

Future<void> _firebaseMessagingBackgroundHandler(RemoteMessage message) async {
  await Firebase.initializeApp();

  print('Handling a background message ${message.messageId}');
}

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

  AndroidInitializationSettings androidSettings =
      AndroidInitializationSettings("@mipmap/ic_launcher");

  DarwinInitializationSettings iosSettings = DarwinInitializationSettings(
      requestAlertPermission: true,
      requestBadgePermission: true,
      requestCriticalPermission: true,
      requestSoundPermission: true);

  InitializationSettings initializationSettings =
      InitializationSettings(android: androidSettings, iOS: iosSettings);

  bool? initialized = await notificationsPlugin.initialize(
      initializationSettings, onDidReceiveNotificationResponse: (response) {
    log(response.payload.toString());
  });

  log("Notifications: $initialized");

  await Firebase.initializeApp();
  currentFirebaseUser = FirebaseAuth.instance.currentUser;
  FirebaseMessaging.onBackgroundMessage(_firebaseMessagingBackgroundHandler);

  await FirebaseMessaging.instance.setForegroundNotificationPresentationOptions(
      alert: true, badge: true, sound: true);

  await UserSimplePrefences.init();
  //await FirebaseAuth.instance.currentUser;
  runApp(MyApp());
}

This is where I handle the messages and move to other window and do stuffs

class PushNotificationService {
  FirebaseMessaging firebasemessaging = FirebaseMessaging.instance;
  Future initialize(context) async {
    FirebaseMessaging.onMessage.listen((RemoteMessage message) {
      RemoteNotification? notification = message
          .notification; //assign two variables for remotenotification and android notification
      AndroidNotification? android = message.notification?.android;
      if (notification != null && android != null) {
        retrieveRideRequestInfo(getRideRequestId(message.data)!, context);

        notificationsPlugin.show(
          notification.hashCode,
          notification.title,
          notification.body,
          NotificationDetails(
            iOS: DarwinNotificationDetails(
              presentAlert: true,
              presentBadge: true,
              presentSound: true,
            ),
            android: AndroidNotificationDetails("Driver", "You have a new ride",
                priority: Priority.max, importance: Importance.max),
          ),
        );
        print('AndroidNotification after clicking ' + notification.title!);
        print('AndroidNotification after clicking ' + notification.body!);
        print("This is message map");

        //getRideRequestId(message);
      }
    });

    //on message open
    FirebaseMessaging.onMessageOpenedApp.listen((RemoteMessage message) {
      // same as above
      RemoteNotification? notification = message
          .notification; //assign two variables for remotenotification and android notification
      AndroidNotification? android = message.notification?.android;
      if (notification != null && android != null) {
        // if (doublenotification.isOdd)
        retrieveRideRequestInfo(getRideRequestId(message.data)!, context);

        print('AndroidNotification after clicking ' + notification.title!);
        print('AndroidNotification after clicking ' + notification.body!);

        //getRideRequestId();
      }
      //}
    });
  }
}

In android it works fine however in IOS, there is absolutely nothing happening, no logs ,notifications or error, what am I missing here ?
