Hi I think this was caused by this line https://github.com/FirebaseExtended/flutterfire/blob/4511f7c21a63a77b9ef69344402574cced5c5d07/packages/firebase_messaging/android/src/main/java/io/flutter/plugins/firebasemessaging/FlutterFirebaseMessagingService.java#L147

which in my understanding are can not find callback for handling incoming message while in background?
Maybe skip the line without logging, or change the log into Info / Warn instead of Fatal?
