fix a flutter code using background FCM firebase cloud messaging on IOS

important:

- please read the description carefully, don't waste my time if you don't know what iam talking about in the post
- this project needs professional flutter developers with extensive experience of working with background processes and firebase push notifications (FCM)
- this project requires that you have IOS development environment and real IOS device for testing

project target: the following source code

https://github.com/firebase/flutterfire/blob/master/packages/firebase_messaging/firebase_messaging/example/

contains a flutter project for implementing firebase FCM messaging on both android and ios

the following function is called when the application is on background or terminated, the target of this function is to execute code automatically once a notification is received
(without clicking the notification), currently this function only prints some output to the console

@pragma('vm:entry-point')
Future<void> _firebaseMessagingBackgroundHandler(RemoteMessage message) async {
await Firebase.initializeApp(options: DefaultFirebaseOptions.currentPlatform);
await setupFlutterNotifications();
showFlutterNotification(message);
// 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.
print('Handling a background message ${message.messageId}');
}

the above function works only on android but it's never called on ios device

so our target is to make this function called on IOS as well
