I committed a hack that makes the example slightly better. If you use setPreferredOrientations twice with only portraitDown first the app is not stuck in portrait orientation forever, but instead can be "reset".

The changes:

  Future<void> _setOrientationToPortrait() async {
    await SystemChrome.setPreferredOrientations(<DeviceOrientation>[
      DeviceOrientation.portraitDown,
    ]);
    await SystemChrome.setPreferredOrientations(<DeviceOrientation>[
      DeviceOrientation.portraitDown,
      DeviceOrientation.portraitUp,
    ]);
  }

Steps to "Reset":

Do all the above steps to get stuck in portrait mode on form widget page
Physically rotate the phone back to portrait
Close the form widget page
Reopen the form widget page (still in portrait)
You are able to rotate to landscape

This is the best setup I have found so far as a hacky solution but there may be a better one.
