flutter firebase background notification not working for iOS

I’m implementing Firebase Cloud Messaging (FCM) in my Flutter app to deal with push notifications. Nevertheless, I’ve encountered the next concern:

• Foreground: Notifications are obtained and processed efficiently.
• Background or Terminated: Notifications usually are not obtained, and I can’t deal with them.

I’ve appeared all the different questions and solutions however I could not clear up my drawback even I attempt every part

Variations

• Flutter 3.24.5 • channel secure
• Xcode Model 16.1
• firebase_messaging: ^15.1.6
• flutter_local_notifications: ^18.0.1
• IOS 18

fundamental.dart

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

  // Firebase'i başlatın

  // Burada bildirimi işleyebilirsiniz
}

void fundamental() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp(
    choices: DefaultFirebaseOptions.currentPlatform,  // Firebase config dosyasını doğru şekilde eklediğinizden emin olun.
  );
  NotificationSettings settings = await FirebaseMessaging.occasion.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


@fundamental
@objc class AppDelegate: FlutterAppDelegate {
 override func software(
 _ software: UIApplication,
 didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
 ) -> Bool {
// That is required to make any communication accessible within the motion isolate.
 FlutterLocalNotificationsPlugin.setPluginRegistrantCallback { (registry) in
 GeneratedPluginRegistrant.register(with: registry)
 }

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


 GeneratedPluginRegistrant.register(with: self)
 return tremendous.software(software, didFinishLaunchingWithOptions: launchOptions)
 }

}
