 ## Testing for Flutter

 For manual testing, the usual way in native Android is testing using Accessibility Scanner. Unfortunatelly that doesn't work with Flutter yet ([see open issue](https://github.com/flutter/flutter/issues/39531)).
 You can use TalkBack, but that's mainly inteded for real users that needs accessibility features. It's good so you know how everything works for user, but it's a bit complex and slow to use for testing.
