Hi,
In order to reproduce this I would need a bit more of information of your steps: Did you apply any changes to the code after adding the firebase_messaging service or did it just happen when adding the dependency to the yaml file? Are you trying to open the ARView in a different way? Could you reproduce the issue with more than 1 device? Which SDK version are you using?
Best regards,
Aitor.

I have a project with Wikitude which was working as expected and I have recently added a firebase_messaging service to add push notification functionality on the app.
From the moment I have added the firebase_messaging (FCM) I get an error:
E/MethodChannel#wikitude_plugin(18491): java.lang.NullPointerException: Attempt to invoke virtual method 'int android.app.Activity.checkPermission(java.lang.String, int, int)' on a null object reference

The code that inits the ARView with it's permissions isn't changed. I have tried to debug and the response from the _channel.invokeMethod('requestARPermissions', features); within the requestARPermissions function rises the error.
Do you have any idea why this happens?
