I’m implementing Firebase Cloud Messaging (FCM) in my Flutter app to handle push notifications. However, I’ve encountered the following issue:

• Foreground: Notifications are received and processed successfully.
• Background or Terminated: Notifications are not received, and I can’t handle them.

I have looked all of the other questions and answers but I couldn’t solve my problem even I try everything

Versions

• Flutter 3.24.5 • channel stable
• Xcode Version 16.1
• firebase_messaging: ^15.1.6
• flutter_local_notifications: ^18.0.1
• IOS 18

main.dart

@pragma('vm:entry-point')
Future<void> _firebaseMessagingBackgroundHandler(RemoteMessage message) async {
  print("Handling a background message: ${message.messageId}");

  // Firebase'i başlatın

  // Burada bildirimi işleyebilirsiniz
}

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp(
    options: DefaultFirebaseOptions.currentPlatform,  // Firebase config dosyasını doğru şekilde eklediğinizden emin olun.
  );
  NotificationSettings settings = await FirebaseMessaging.instance.requestPermission(
      alert: true,
      announcement: false,
      badge: true,
      carPlay: false,
      criticalAlert: false,
      provisional: false, // Zorunlu bildirim yerine geçici izni aktive eder
      sound: true,
    );

  FirebaseMessaging.onBackgroundMessage(_firebaseMessagingBackgroundHandler);

  runApp(MyApp());
}

AppDelegate.swift

import UIKit
import Flutter
import Firebase
import FirebaseCore
import flutter_local_notifications


@main
@objc class AppDelegate: FlutterAppDelegate {
 override func application(
 _ application: UIApplication,
 didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
 ) -> Bool {
// This is required to make any communication available in the action isolate.
 FlutterLocalNotificationsPlugin.setPluginRegistrantCallback { (registry) in
 GeneratedPluginRegistrant.register(with: registry)
 }

 if #available(iOS 10.0, *) {
 UNUserNotificationCenter.current().delegate = self as UNUserNotificationCenterDelegate
 }


 GeneratedPluginRegistrant.register(with: self)
 return super.application(application, didFinishLaunchingWithOptions: launchOptions)
 }

}
