firebase - _auth.signInWithCredential不起作用(卡住)

我遇到了Firebase电话身份验证的问题，在该问题中，当我使用_auth.signInWithCredential()时，它不会从功能中消失并卡在那里。
这是我的代码:

Future<void> verifyPhoneNumber(String phoneNumber) async {
    await _auth.verifyPhoneNumber(
        phoneNumber: phoneNumber,
        timeout: Duration(seconds: 60),
        verificationCompleted: (AuthCredential credential) async {
          print('Verification OTP completed');
          AuthResult result = await _auth.signInWithCredential(credential);
          FirebaseUser user = result.user;
          if (user != null) {
            print('User is not null!');
            Navigator.pushReplacementNamed(context, 'home');
          }
        },
        verificationFailed: (AuthException exception) async {
          print('There was a problem sending the otp');
          print(exception.code);
          print(exception.message);
        },
        codeSent: (String verificationID, [int forceResendingToken]) {

          createAlertDialog(context, widget.isFromGoogleAuth, verificationID);
        },
        codeAutoRetrievalTimeout: null);
  }

接下来，当用户按下按钮时，我运行此命令:

onTap: (pin) async {
                    otpText = pin.trim();
                    print('$otpText');
                    AuthCredential credential = PhoneAuthProvider.getCredential(
                        verificationId: verificationID, smsCode: otpText);
                    print('${verificationID}');
                    print('${credential.providerId}');

//everything until now has been printed, nothing is null

                    AuthResult authResult = await _auth
                        .signInWithCredential(credential)
                        .then((value) {

//this value is not printed

                      print('${value.user.phoneNumber}');
                    });

//The next line of code doesnt get run, and it doesnt print value.user.phone number

                    print('I HAVE REACHED HERE');
                    FirebaseUser user = authResult.user;
                    if (user != null) {
                      Navigator.pushReplacementNamed(context, 'home');
                    } else {}
                  },

最佳答案

问题在于，在测试用户中，我添加了我的电话号码，而不是使用在其中分配的OTP代码，而是使用一些发送到我的电话的旧OTP代码，这导致signInWithCredential引发错误。感谢您的帮助，我非常感谢
