Klarna payment view auth problem

[AlexXer]

Describe the bug
I am writing native android module for flutter with using klarna SDK. I have custom view with klarna payment view and when Klarna payment view authorizes I have endless progress and no auth fields. In logs I have that Klarna payment view is AppCompat widjet and we should use AppCompat theme. But theme extends from AppCompat. In some sources told that we should have AppCompatActivity and AppCompat theme. But for render native view from flutter we need to extend activity from FlutterActivity.
