Flutter firebase messaging gives registerPlugin exception in Android

Question

Everything was fine until the last Flutter upgrade to beta 2.0.1 (same as current stable I think).

Now I suddenly get this message during init of the firebase messaging.

NoSuchMethodError: No top-level getter '_registerPlugins' declared.
Receiver: top-level
Tried calling: _registerPlugins

This error is triggered by calling:

FirebaseMessaging.onBackgroundMessage(_firebaseMessagingBackgroundHandler);

Down the call path this calls:

package: firebase_messaging_platform_interface-1.0.0-dev.10
file   : method_channel_messaging.dart:

await channel.invokeMapMethod('Messaging#startBackgroundIsolate', {
          'pluginCallbackHandle': bgHandle.toRawHandle(),
          'userCallbackHandle': userHandle.toRawHandle(),
});

That ends up in:

package: flutter
file   : platform_channel.dart:

final ByteData? result = await binaryMessenger.send(
  name,
  codec.encodeMethodCall(MethodCall(method, arguments)),
);

Seems like the exception is thrown here...

Those are the messages it generates in my console. Nothing that indicates a problem I think:

Does anybody have any suggestions?
