My main.dart code is

Future<void> _firebaseMessagingBackgroundHandler(RemoteMessage message) async {
   // If you're going to use other Firebase services in the background, such as Firestore,
   // make sure you call `initializeApp` before using other Firebase services.
   await Firebase.initializeApp();

   print("Handling background message : ${message.messageId}");
}

future<void> main() async {
   WidgetsFlutterBinding.ensureInitialized();

   await Firebase.initializeApp(
     name: 'eco-city-deeplink',
     options: DefaultFirebaseOptions.currentPlatform,
   );

   //Request for permission -
   FirebaseMessaging messaging = FirebaseMessaging.instance;

   NotificationSettings settings = await messaging.requestPermission(
     alert: true
     announcement: false
     badge: true
     carPlay: false
     criticalAlert: false
     provisional: false
     sound: true
   );

   if (settings.authorizationStatus == AuthorizationStatus.authorized) {
     print('User granted permission');
   } else if (settings.authorizationStatus == AuthorizationStatus.provisional) {
     print('User granted temporary permission');
   } else {
     print('User denied or did not accept permission');
   }

   //Messages in the foreground
   FirebaseMessaging.onMessage.listen((RemoteMessage message) {
     print('Got a message while in the foreground!');
     print('Message data: ${message.data}');

     if (message.notification != null) {
       print('The message also contained a notification: ${message.notification}');
     }
   });

   FirebaseMessaging.onBackgroundMessage(_firebaseMessagingBackgroundHandler);

   runApp(MyApp());
}

Settings cloud messaging in firebase -

my key in developer.apple -

my profiles in developer.apple -

I tried to wait a very long time, but not a single notification came to me.
PS - Yes, I'm testing on a real device

And my testing messaging -

Tell me what I did wrong? Why am I not receiving test messages?

PS: Apparently, it should be clarified, I'm trying to send not to one device, but to everything that received a request to send notifications when the application starts

my AppDelegate.swift -

import UIKit
import Flutter

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) -> Bool {
    GeneratedPluginRegistrant.register(with: self)
    return super.application(application, didFinishLaunchingWithOptions: launchOptions)
  }
}

just for the future, try to put [redacted] or something at the place where your API-key is in the config. This would prevent someone else from stealing it and sending messages on your behalf or worse.

Would like to ask, if you registered your phone to FCM by calling the getToken function?
https://firebase.google.com/docs/cloud-messaging/flutter/client?hl=en#access_the_registration_token

// It requests a registration token for sending messages to users from your App server or other trusted server environment.
String? token = await messaging.getToken();

if (kDebugMode) {
  print('Registration Token=$token');
}

This call would print the token in the console while debugging. It is useful, if you want to target your phone directly, but also necessary to make your phone "targetable" at all.

Please let me know if this fixes your problem.

Best regards

please check this configuration for your AppDelegate.swift

import UIKit
import Flutter
import Firebase

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