        appBar: AppBar(
          title: Text('OTP Input Demo'),
        ),
        body: Column(
          children: [
            OtpInputField(
              onCodeSubmitted: (code) async {
                // Handle the submitted OTP code
                print('OTP Submitted: $code');
                // Return true if code is valid, false otherwise
                return true;
              },
            ),
            const Spacer(),

OtpInputField(
  onCodeSubmitted: (code) async {
    // Handle the submitted OTP code
    print('OTP Submitted: $code');
    // Return true if code is valid, false otherwise
    return true;
  },

  buttonStyle: TextButton.styleFrom(
    backgroundColor: Colors.grey.shade200,
