[firebase_messaging] Crash when set onBackgroundMessage #125
Description
The following code causes immediate crash after app launching:
// Top Level. I also tried code from readme, no success.
Future<dynamic> myBackgroundMessageHandler(dynamic message) {
return Future.value(0);
}
_firebaseMessaging.configure(
onMessage: (d) async { print('on message'); handleMessage(d); },
onBackgroundMessage: myBackgroundMessageHandler,
onLaunch: (d) async { print('on launch'); handleMessage(d); },
onResume: (d) async { print('on resume'); handleMessage(d); },
);
If myBackgroundMessageHandler method isn't on top level, then it's not crashing, but throws null exception ("'toRawHandle' was called on null")
Without onBackgroundMessage: myBackgroundMessageHandler, all works fine.
