  );

  runApp(MyApp());

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: PhoneInputScreen(
        actions: [
          SMSCodeRequestedAction(
            (context, action, flowKey, phone) {
              Navigator.of(context).push(
                MaterialPageRoute(
                  builder: (_) => SMSCodeInputScreen(
                    action: action,

Thanks for the detailed report @kulture-rob-snider I am seeing the same behavior using the code sample provided.

Maybe @lesnitsky will have an idea since it's flutterfire_ui related?

[lesnitsky]

Most likely it is fixed on #9343, but I'll double check
