类型“List<Object?>”不是类型“PigeonUserDetails”的子类型？类型转换

Question

我正在尝试使用 Firebase 使用 Google 登录并尝试注册用户名和帐户。基本上我尝试执行的任何身份验证过程都会收到以下错误：

未处理的异常：“List”类型不是“PigeonUserDetails”类型的子类型？类型转换

这是我的谷歌登录和使用用户名和密码注册的代码：

class LoginAccountBloc extends Bloc<LoginAccountEvent, LoginAccountState> {
  LoginAccountBloc() : super(LoginAccountInitial()) {
    on<LoginAccountSubmitted>(
      (event, emit) async {
        emit(LoginAccountSubmitting());
        try {
          await FirebaseAuth.instance.signInWithEmailAndPassword(
            email: event.email,
            password: event.password,
          );
          emit(LoginAccountSuccessful());
        } on FirebaseAuthException catch (e) {
          if (e.code == 'user-not-found') {
            emit(LoginAccountFailure('No user found for that email.'));
          } else if (e.code == 'wrong-password') {
            emit(LoginAccountFailure('Wrong password provided for that user.'));
          } else {
            emit(LoginAccountFailure(e.toString()));
          }
        }
      },
    );
  }
}



class RegisterAccountBloc
    extends Bloc<RegisterAccountEvent, RegisterAccountState> {
  RegisterAccountBloc() : super(RegisterAccountInitial()) {
    on<RegisterAccountSubmitted>(
      (event, emit) async {
        print(event.username);
        print(event.email);
        print(event.password);
        emit(RegisterAccountSubmitting());
        if (event.username.isEmpty ||
            event.email.isEmpty ||
            event.password.isEmpty) {
          emit(RegisterAccountFailure("All fields are required."));
          return;
        }
        print('All fields are written');
        try {
          // Step 1: Create a new user with Firebase Authentication

          final credential =
              await FirebaseAuth.instance.createUserWithEmailAndPassword(
            email: event.email,
            password: event.password,
          );
          print('Added Credentials to FirebaseAuth');
        } on FirebaseAuthException catch (e) {
          if (e.code == 'weak-password') {
            emit(RegisterAccountFailure('The password provided is too weak.'));
          } else if (e.code == 'email-already-in-use') {
            emit(RegisterAccountFailure(
                'The account already exists for that email.'));
          } else {
            emit(RegisterAccountFailure(e.toString()));
          }
        }

        try {
          CollectionReference users =
              FirebaseFirestore.instance.collection('User');
          print("Trying to add");
          await users.add({
            'username': event.username,
            'email': event.email,
            'password': event.password
          });
          print("User Created");
          emit(RegisterAccountSuccess());
        } catch (error) {
          emit(RegisterAccountFailure(error.toString()));
        }
      },
    );
  }
}

我尝试调试了几个小时，但此时没有任何变化的迹象。在 firebase 开始在身份验证选项卡中显示此消息之前它正在工作。

您的代码没有任何问题，这是一个 firebase 身份验证问题，我也遇到了同样的问题，所做的就是将 firebase_auth 和 firebase_core 更新到最新版本，然后重新运行应用程序，这解决了我的问题。
