[Firebase_messaging]: On iOS, subsequent notifications with same collapse ID do not trigger onMessage listener in foreground

[kilobitter]

Is there an existing issue for this?

• I have searched the existing issues.

Which plugins are affected?

Messaging

Which platforms are affected?

iOS

Description

As the title states, in our app (and seemingly in general), if we send several notifications with the same collapse ID (So that the notifications collapse to a single one in the notification centre), in Android this works as expected, the notifications collapse into one but if the app is in the foreground the onMessage listener gets triggered with every push notification.

On iOS however, only the first of these notifications triggers the listener. All subsequent notifications do generate a notification in the notification centre, but the listener does not get triggered anymore, unless the collapse ID is changed.

Reproducing the issue

1. Create an app with Firebase_messaging support on any Apple device
2. Have an instance of firebaseMessenger.onMessage.listen() that prints a message to the console
3. From your back-end, send an FCM push notification with a certain "apns-collapse-id"
4. It triggers the listener
5. Send another notification with the same "apns-collapse-id"
6. The listener does not get triggered anymore

Hello there, I have not been able to reproduce your issue, the listener still works with further notifications sent with the same "apns-collapse-id" when it is clicked on. I can suggest upgrading your dependencies but otherwise an MRE would be helpful.

Hey @kilobitter. We need more information to resolve this issue but there hasn't been an update in 7 weekdays. I'm marking the issue as stale and if there are no new updates in the next 7 days I will close it automatically.

I have the same problem only on iOS, but no notification triggers onMessage.

I am using the following versions:

  firebase_core:

This is the sended message:

fcm_message = {
    "message": {
        "data": data,
        "token": firebase_token,
        "notification": {
            "title": data.get("title"),
            "body": data.get("body")
        },
        "android": {
            "priority": "HIGH",
            "ttl": "120s",,
            "fcm_options": {"analytics_label": "***"}
        },
        "apns": {
            "headers": {
                "apns-priority": "10",
                "apns-push-type": "alert",
                "apns-collapse-id": "***",
                "apns-expiration": str(int(time.time()) + 120)
            },
            "payload": {
                "aps": {
                    "alert": {
                        "title": data.get("title"),
                        "body": data.get("body"),
                    },
                    "sound": "default",
                    "category": "***"
                },
            },
            "fcm_options": {"analytics_label": "***"}
        }
    }
}

On older versions it worked!
