这是状态类Code

class SignInState {
  String email;
  String password;
  bool passwordVisible;

  SignInState(
      {this.email = "", this.password = "", this.passwordVisible = false});

  List<Object> get props => [this.email, this.password, this.passwordVisible];

  SignInState copyWith(
      {String? email, String? password, bool? passwordVisible}) {
    return SignInState(
        email: email ?? this.email,
        password: password ?? this.password,
        passwordVisible: passwordVisible ?? this.passwordVisible);
  }
}

// class SignInInitial extends SignInState {
//   SignInInitial({
//     String email = "",
//     String password = "",
//     bool passwordVisible = false,
//   }) : super(
//             email: email, password: password, passwordVisible: passwordVisible);
// }

class SignInLoading extends SignInState {}

class SignInSuccess extends SignInState {}

class SignInError extends SignInState {
  final String error;
  SignInError({required this.error});
}

字符串

此为事件类代码

@immutable
    sealed class SignInEvent {}
    
    class SignInEmailEvent extends SignInEvent {
      final String email;
    
      SignInEmailEvent({required this.email});
    }
    
    class SignInPasswordEvent extends SignInEvent {
      final String password;
    
      SignInPasswordEvent({required this.password});
    }
    
    class SignInPasswordVisibleEvent extends SignInEvent {
      final bool passwordVisible;
    
      SignInPasswordVisibleEvent({required this.passwordVisible});
    }
    
    class SignInLoginButtonEvent extends SignInEvent {}
    
    class SignInRegisterButtonEvent extends SignInEvent {
      final String email;
      final String password;
    
      SignInRegisterButtonEvent({required this.email, required this.password});
    }

**This is the BloC Code**

class SignInBloc extends Bloc<SignInEvent, SignInState> {
  SignInBloc() : super(SignInState()) {
    on<SignInEmailEvent>((event, emit) {
      // print("Email is ${event.email}");
      emit(state.copyWith(
        email: event.email,
      ));
    });
    on<SignInPasswordEvent>((event, emit) {
      // print("Email is ${event.password}");
      emit(state.copyWith(password: event.password));
    });
    on<SignInPasswordVisibleEvent>(
      (event, emit) =>
          emit(state.copyWith(passwordVisible: event.passwordVisible)),
    );
    on<SignInLoginButtonEvent>(
      (event, emit) async {
        String email = state.email;
        String password = state.password;

        print("Email is $email" + "Password is $password");

        if (email.isEmpty) {
          // print("Please enter email and password");
          emit(SignInError(error: "Please Enter Email"));
        } else if (password.isEmpty) {
          // print("Please enter email and password");
          emit(SignInError(error: "Please Enter password"));
        }
        try {
          final credential = await FirebaseAuth.instance
              .signInWithEmailAndPassword(email: email, password: password);
          // print("I am Here");
          if (credential.user == null) {
            // print("User Not Found");
            emit(SignInError(error: "User Not Found"));
          }
          if (credential.user!.emailVerified == false) {
            // print("Email Not Verified");
            emit(SignInError(error: "Email Not Verified"));
          }
          var user = credential.user;
          if (user != null) {
            emit(SignInSuccess());
            //emit(SignInSuccess());
          }
        } on FirebaseAuthException catch (e) {
          if (e.code == "user-not-found") {
            //print("User Not Found");
            emit(SignInError(error: "User Not Found"));
          } else if (e.code == 'wrong-password') {
            //print("Wrong Password");
            emit(SignInError(error: "Wrong Password"));
          } else if (e.code == 'invalid-email') {
            //print("Invalid Email");
            emit(SignInError(error: "Invalid Email"));
          }
        }
      },
    );
  }

我找不到我哪里做错了。键入电子邮件并按注册按钮打印-电子邮件是miraj密码是键入通行证并按注册按钮打印-电子邮件是密码是123为什么电子邮件/密码设置为空？还有，设置电子邮件并一起传递打印-电子邮件是miraj密码是123再次点击打印-电子邮件是密码是两者都设置为null。如何解决此问题？
