konnte dieses Problem behoben werden?

Arbeite zurzeit mit alter Version. Denke dieses Problem hat noch keine Priorität. Ok wenn ich dies in den Weihnachtsferien angehe?

Konnte es lösen, Problem wird hier beschriben : https://stackoverflow.com/questions/57689492/flutter-unhandled-exception-servicesbinding-defaultbinarymessenger-was-accesse

Bei uns war das Erzeugen des objektes Firebase vor runApp das Problem.

WidgetsFlutterBinding.ensureInitialized();

Hatt aus irgend einem Grund nicht geklappt, nach runApp funktioniert es aber.
