[Firebase Messaging] iOS not receiving push notifications sent from device but working when sent from firebase console

[callumclift]

Describe the bug

I'm not receiving any push notifications at all on iOS devices when sending messages from within my app to individually targeted devices. Nothing comes through in the tray at all and the onMessage handler is not getting fired at all no matter if the app is open, in the background or closed. I'm just not receiving anything at all, i'm using both a real iPhone X and an iPad.

When I send a message to all users through the firebase console the push notification is received on iOS devices and the onMessage handler is working so devices are clearly set up to receive push notifications correctly.

Messages are received totally fine on Android when sending from within the app so I don't think it's an issue in the way i'm sending the messages.

I'm using the latest version of the firebase messaging plugin (firebase_messaging: ^6.0.9)

Is this a know issue? Is anyone else experiencing this? Really frustrating as push notifications are vital to users of my app

This is my code for sending the notification:

await http.post(
          'https://fcm.googleapis.com/fcm/send',
          headers: <String, String>{
            'Content-Type': 'application/json',
            'Authorization': 'key=$cloudMessagingServerKey',
          },
          body: jsonEncode(
            <String, dynamic>{
              'notification': <String, dynamic>{
                'body': body,
                'title': title
              },
              'priority': 'high',
              'data': <String, dynamic>{
                'click_action': 'FLUTTER_NOTIFICATION_CLICK',
              },
              'to': token,
            },
          ),
        );

I think I'm having a similar issue.
The payload received on Android is different from iOS.

My current work around is to check platform first then process the notification.
E.g. I include a type key in my payload:

var messageType = Platform.isIOS ? message['type'] : message['data']['type'];

Hi @callumclift
did @charkala workaround fix the problem?
thank you

[charkala]

@iapicca it didn't work and after some trial/error research and found to have the same issue outlined in #1829

Closing in favour of trying the latest messaging version which has since this issue was created been heavily reworked to improve it along with detailed documentation: https://firebase.flutter.dev/docs/messaging/overview

If you still have a problem please raise a new GitHub issue with up to date information and code snippets if possible. Thanks.
