iOS push notifications not working in flutter

Question

My app needs push notifications. I just follow the flutterfire guide, with android working correctly but not for iOS app... I consider the error are in configuration of notifications, because the code never execute print("PUSH RECEIVED"); inside FirebaseMessaging.onMessage.listen() or FirebaseMessaging.onBackgroundMessage().

My flutter doctor -v:

  static Future init() async {

    // Declaration of variables
    FirebaseMessaging firebaseMessaging = FirebaseMessaging.instance;
    NotificationSettings settings = await firebaseMessaging.requestPermission(
      alert: true,
      announcement: false,
      badge: true,
      carPlay: false,
      criticalAlert: false,
      provisional: false,
      sound: true,
    );

    print('User granted permission: ${settings.authorizationStatus}');

    if(Platform.isIOS){
      await firebaseMessaging.setForegroundNotificationPresentationOptions(
        alert: true, // Required to display a heads up notification
        badge: true,
        sound: true,
      );
    }
  }

  ...

}

In the other hand I configured whole Firebase:

• Created new iOS app
• Added Team ID and Appstore ID
• Added APNS autentication key with Key ID and Team ID

Any ideas the reason that iOS devices not receiving puhs notifications? I think I gives all necessary information if you need something, tell me! Thanks in advance!

Solution

I also have the same issue with firebase push notification in ios. My android push notification was working properly but not in ios.

What I did was to follow the instruction provided by firebase to integrate Push notification(Not the flutter guide but the ios one) Follow this link https://firebase.google.com/docs/cloud-messaging/ios/client

In ios user have to give permission to send push notification for them unlike android so the thing you want to do is add the below code to AppDelegate.swift

if #available(iOS 10.0, *) {
  // For iOS 10 display notification (sent via APNS)
  UNUserNotificationCenter.current().delegate = self
  let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
  UNUserNotificationCenter.current().requestAuthorization(
    options: authOptions,
    completionHandler: { _, _ in }
  )
} else {
  let settings: UIUserNotificationSettings =
    UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
  application.registerUserNotificationSettings(settings)
}
application.registerForRemoteNotifications()

Hope this works
