Confirmation Screen is below

class ConfirmCodeScreen extends StatefulWidget {
    @override
    _ConfirmCodeScreenState createState() => _ConfirmCodeScreenState();
}

class _ConfirmCodeScreenState extends State<ConfirmCodeScreen> {
    final codeControl = InputCodeControl(inputRegex: '^[0-9]*');
    
    @override
    Widget build(BuildContext context) {
        return Scaffold(
            body: SafeArea(
                child: Container(
                    padding: EdgeInsets.symmetric(horizontal: consts.APP_PADDING),
                  child: Column(
                      mainAxisAlignment: MainAxisAlignment.center,
                      children: [
                          InputCodeField(
                            control: codeControl,
                            count: 4,
                            inputType: TextInputType.number, 
                            decoration: InputCodeDecoration(
