I am using FirebaseAuth for Sent OTP and validate users number.But facing 'verificationCompleted != null' this Error

This is My Code

 Future<void> registerUser(BuildContext context) async {
      await FirebaseAuth.instance.verifyPhoneNumber(
      phoneNumber: mobileNum,
      timeout: const Duration(seconds: 15),
      verificationCompleted: (AuthCredential authCredential) {
        setState(() {
          authStatus = "Your account is successfully verified";
        });
      },
      verificationFailed: (FirebaseAuthException e) {
        print(e);
      },
      codeSent: (String verId, [int forceCodeResent]) {
        var verificationId = verId;
        setState(() {
          authStatus = "OTP has been successfully send";
        });
      },
      codeAutoRetrievalTimeout: (String verId) {
        var verificationId = verId;
        setState(() {
          authStatus = "TIMEOUT";
        });
      },
    );
 }

not sure of your problem but it says : ERROR_SESSION_EXPIRED, The sms code has expired and in _auth.verifyPhoneNumber() your Timeout duration is quite low. try 60 Seconds.

await _auth.verifyPhoneNumber(
        phoneNumber: '+91${_phoneNumberController.text}',
        timeout: Duration(seconds: 60),
        verificationCompleted: verificationCompleted,
        verificationFailed: verificationFailed,
        codeSent: codeSent,
        codeAutoRetrievalTimeout: codeAutoRetrievalTimeout);

also take look at the docs.
