With this code

RawKeyboardListener(

  focusNode: FocusNode(),
  onKey: (event) {
    print(event);
  },
  child: Text('Test'),
),

when I press "1", it prints this:

Thank you for reporting the bug. It seems like a flutter-elinux tools bug?

Moved to sony/flutter-embedded-linux#261. Don't think it is flutter-elinux bug.
