Flutter Firebase Phone Authentication not working

Phone authentication getting failed with the following exception :

PlatformException(ERROR_SESSION_EXPIRED, The sms code has expired. Please re-send the verification code to try again., null)

But it works if I use a different phone number other than that on my phone. I've added both SHA-1 and SHA-256 fingerprints from the play store to firebase and also replaced the google-services.json.

Here's my code :

 void _verifyPhoneNumber() async {
    setState(() {
       isVerified=true; 
      });
    setState(() {
      _message = '';
    });
    final PhoneVerificationCompleted verificationCompleted =
        (AuthCredential phoneAuthCredential) {
      _auth.signInWithCredential(phoneAuthCredential);
      setState(() {
        _message = 'Received phone auth credential: $phoneAuthCredential';

      });
    };

    final PhoneVerificationFailed verificationFailed =
        (AuthException authException) {
        _message =
            'Phone number verification failed';

    };

    final PhoneCodeSent codeSent =
        (String verificationId, [int forceResendingToken]) async {
      _verificationId = verificationId;

    };

    final PhoneCodeAutoRetrievalTimeout codeAutoRetrievalTimeout =
        (String verificationId) {
      _verificationId = verificationId;
    };

    await _auth.verifyPhoneNumber(
        phoneNumber: '+91'+_phoneNumberController.text,
        timeout: const Duration(seconds: 5),
        verificationCompleted: verificationCompleted,
        verificationFailed: verificationFailed,
        codeSent: codeSent,
        codeAutoRetrievalTimeout: codeAutoRetrievalTimeout);
  }

  // Example code of how to sign in with phone.
  void _signInWithPhoneNumber() async {
    setState(() {
      isLoading=true;
    });
    final AuthCredential credential = PhoneAuthProvider.getCredential(
      verificationId: _verificationId,
      smsCode: _smsController.text,
    );
    try{
      firebaseUser =
        (await _auth.signInWithCredential(credential)).user;
    final FirebaseUser currentUser = await _auth.currentUser();
    assert(firebaseUser.uid == currentUser.uid);
      if (firebaseUser != null) {
.....

      } else {

        _message = 'Sign in failed';
        showErrorDialog();
      }

    }catch (e){
      showErrorDialog();
    }
    setState(() {
      isLoading=false;
    });
  }

If you missed timeout: Duration(seconds: 60) in your

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

This issue may happen

Its late ,but for others who are struggling, it's all is about the incomplete explanation of docs for login and signup.

comment the code of signin in _verifyPhoneNumber() function, add async to the function and make AuthCredential to PhoneAuthCredential

  final PhoneVerificationCompleted verificationCompleted =
    (PhoneAuthCredential phoneAuthCredential) async{
 // comment the below code for _auth.signIn and add async

 // _auth.signInWithCredential(phoneAuthCredential);
  setState(() {
    _message = 'Received phone auth credential: $phoneAuthCredential';

  });

Actually the _verifyPhoneNumber() checks the number in database ,so you can redirect user direct to Home Screen from this function.As the signIn runs two times ,one here and one in signinwithPhone Number() , so it gives timeout error.

Right,although timeout property is 60s. But after receiving the verification code and pasting the code immediately, ERROR_SESSION_EXPIRED like you. note: only on Android,just receive on a few phone number.

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);

and if this didn't help give a look at the docs .
