void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(),
        body: Center(
          child: Column(
            mainAxisAlignment: MainAxisAlignment.center,
            children: <Widget>[
              PasscodeTextField(
                onTextChanged: (passcode) {
                  print(passcode);
                },
                totalCharacters: 4,
                borderColor: Colors.black,
                passcodeType: PasscodeType.number,
              ),
            ],
          ),
        ),
      ),
    );
  }
