  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      // initialize the OTP screen by passing validation logic and route callback
      home: OtpScreen(
        otpLength: 4,
        validateOtp: validateOtp,
        routeCallback: moveToNextScreen,
