firebase - 方法 'getCredential' 没有为类型 'PhoneAuthProvider' 定义

Question

据我所知，flutter firebase 身份验证中有许多已弃用的方法。

这是我的代码；

            FlatButton(
              child: Text("Confirm"),
              textColor: Colors.white,
              color: Colors.blue,
              onPressed: () async {
                FirebaseAuth _auth = FirebaseAuth.instance; // I didn't use it here. I did for you to see
                final code = _codeController.text.trim();
                final AuthCredential credential = PhoneAuthProvider.getCredential(
                        verificationId: verificationId, smsCode: code);

                UserCredential result =
                    await _auth.signInWithCredential(credential);

                User user = result.user;

                if (user != null) {
                  Navigator.push(
                      context,
                      MaterialPageRoute(
                          builder: (context) =>
                              HomeScreen(user: user)));
                } else {
                  print("Error");
                }
              },
            )

我尝试进行手机身份验证，但 getCredential 出错。我查看了 firebase 文档。它说 PhoneAuthProvider 已弃用，我应该将 PhoneAuthCredential 与 getCredential 一起使用。我用过，但没用。我在 stackoverflow 上看到关于这个错误的各种问题，但我还找不到解决方法

这就是我在 firebase_auth: ^0.18.0+1 上的应用中实现它的方式:

  @override
  Future<void> signInWithSmsCode(String smsCode) async {
    final AuthCredential authCredential = PhoneAuthProvider.credential(
      smsCode: smsCode,
      verificationId: _verificationCode,
    );
    try {
      await auth.signInWithCredential(authCredential);
    } on PlatformException catch (e) {
      throw _firebaseErrorFactory.getException(e.code);
    } on FirebaseAuthException {
      throw _firebaseErrorFactory
          .getException('ERROR_INVALID_VERIFICATION_CODE');
    }
  }
