Flutter Firebase电话身份验证不起作用

Question

电话认证失败，但有以下异常：

PlatformException（ERROR_SESSION_EXPIRED，短信代码已过期。请重新发送验证码以重试。，为null）

但是如果我使用手机上的其他电话号码，则可以使用。我已经将Play商店中的SHA-1和SHA-256指纹都添加到了Firebase中，并且还替换了google-services.json。

这是我的代码：

 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;
    });
  }

ERROR_SESSION_EXPIRED，短信代码已过期，在_auth.verifyPhoneNumber()中，您的

超时持续时间相当低。尝试60秒。

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