how to pass the model class and return data in flutter - flutter

Question

Model class:
#JsonSerializable()
class EmpVerifyEntity extends Equatable {
#JsonKey(name: "access_token")
final String accessToken;
final EmpVerifyEmployee employee;
const EmpVerifyEntity(this.accessToken, this.employee);
factory EmpVerifyEntity.fromJson(Map<String, dynamic> json) =>
_$EmpVerifyEntityFromJson(json);
Map<String, dynamic> toJson() => _$EmpVerifyEntityToJson(this);
static const empty = EmpVerifyEntity(
'123',
EmpVerifyEmployee(
'1', 'avatar', 'sId', 'empName', 'empId', 'designation', 1));
#override
String toString() {
return jsonEncode(this);
}
#override
// TODO: implement props
List<Object?> get props => [accessToken, employee];
}
#JsonSerializable()
class EmpVerifyEmployee extends Equatable {
#JsonKey(name: "password")
final String password;
final String avatar;
#JsonKey(name: "_id")
final String sId;
#JsonKey(name: "emp_name")
final String empName;
#JsonKey(name: "emp_id")
final String empId;
final String designation;
#JsonKey(name: "__v")
final int iV;
const EmpVerifyEmployee(this.password, this.avatar, this.sId, this.empName,
this.empId, this.designation, this.iV);
factory EmpVerifyEmployee.fromJson(Map<String, dynamic> json) =>
_$EmpVerifyEmployeeFromJson(json);
Map<String, dynamic> toJson() => _$EmpVerifyEmployeeToJson(this);
static const empty = const EmpVerifyEmployee(
'password', 'avatar', 'sId', 'empName', 'empId', 'designation', 1);
#override
String toString() {
return jsonEncode(this);
}
#override
// TODO: implement props
List<Object?> get props =>
[password, avatar, sId, empName, empId, designation, iV];
}
auth repo:
class AuthenticationRepository {
Future<void> logIn({ //login process
required String username,
required String password,
}) async {
print("------------------");
print(username);
var res = await http.post(
Uri.parse("https://cots.com/api/v1/employee/login"),
headers: {
'Content-type': 'application/json',
'Accept': 'application/json'
},
body: jsonEncode({"emp_id": username, "password": password}));
dynamic data = json.decode(res.body);
print(data);
if (data['employee']["is_active"] == true) {
_controller.add(AuthenticationStatus.authenticated);///here it shows authenticated
}
}
User Repo:
class UserRepository {
EmpVerifyEntity? _empVerifyEntity;
UserRepository(this._empVerifyEntity);
Future<EmpVerifyEntity?> getUser() async {
if (_empVerifyEntity != null) {
return _empVerifyEntity;
}
}
}
Auth Bloc:
class AuthenticationBloc
extends Bloc<AuthenticationEvent, AuthenticationState> {
AuthenticationBloc({
required AuthenticationRepository authenticationRepository,
required UserRepository userRepository,
}) : _authenticationRepository = authenticationRepository,
_userRepository = userRepository,
super(const AuthenticationState.unknown()) {
on<AuthenticationStatusChanged>(_onAuthenticationStatusChanged);
on<AuthenticationLogoutRequested>(_onAuthenticationLogoutRequested);
_authenticationStatusSubscription = _authenticationRepository.status.listen(
(status) => add(AuthenticationStatusChanged(status)),
);
}
final AuthenticationRepository _authenticationRepository;
final UserRepository _userRepository;
late StreamSubscription<AuthenticationStatus>
_authenticationStatusSubscription;
#override
Future<void> close() {
_authenticationStatusSubscription.cancel();
_authenticationRepository.dispose();
return super.close();
}
void _onAuthenticationStatusChanged(
AuthenticationStatusChanged event,
Emitter<AuthenticationState> emit,
) async {
switch (event.status) {
case AuthenticationStatus.unauthenticated:
return emit(const AuthenticationState.unauthenticated());
case AuthenticationStatus.authenticated:
final user = await _tryGetUser();
return emit(user != null
? AuthenticationState.authenticated(user)
: AuthenticationState.unauthenticated());
default:
return emit(const AuthenticationState.unknown());
}
}
void _onAuthenticationLogoutRequested(
AuthenticationLogoutRequested event,
Emitter<AuthenticationState> emit,
) {
_authenticationRepository.logOut();
}
Future<EmpVerifyEntity?> _tryGetUser() async {
try {
final user = await _userRepository.getUser();
return user; /////----------------Here I'm getting null as a user
} catch (e) {
print(e);
}
}
}
I can able to do login but can't able to fetch data because it shows null, In login method I should return data so that I can able to fetch. It is authenticated but user data is null, how to pass the return data to userRepo so that I can fetch in authBloc.
