How to access the state outside BlocConsumer and BlocCubit?

Question

I am facing this weird issue, where though I have set the state, but the value when accessed in init state is showing null !!

user_cubit.dart

  UserCubit() : super(UserInitialState()) {
    emit(UserMainLoadingState());
    _firestore
        .collection("users")
        .doc(_currentUser?.uid)
        .snapshots()
        .listen((event) {
      event.exists
          ? {
              emit(UserExists(
                  userModel: UserModel.fromjson(event.data()!, event.id)))
            }
          : {print("There is no such user"), emit(UserNotExists())};
    });
  }

user_state.dart

class UserState extends Equatable {
  final UserModel? userModel;
  const UserState({this.userModel});

  @override
  List<Object?> get props => [userModel];
}

class UserExists extends UserState {
  UserExists({required UserModel userModel}) : super(userModel: userModel) {
    print("I am inside the UserExists state and the user is :$userModel");
  }
}

myWidget.dart

  @override
  void initState() {
     _userState = const UserState();
    print("I am inside the initState The value of userstate is ${_userState.userModel}");  // This prints null , but why ? 
    if (_userState.userModel != null) {
     print("user is ${_userState.userModel.toString()}"); 
     }
    super.initState();
  }

Console log:

I/flutter ( 5029): I am inside the UserExists state and the user is :avatar boy
I/flutter ( 5029):  fullName krrrt
I/flutter ( 5029):  dob 19/1/2022
I/flutter ( 5029):  email [email protected]
I/flutter ( 5029):  phone 12222222255

I/flutter ( 5029): I am inside the initState The value of userstate is null

Though the userState's userModel has value, why can't i access that in the initState.

To access the state of a BLoC or Cubit in Flutter, you can use the context.read<Bloc>(). This method returns a Bloc instance that you can use to access the current state.

initState() {
  super.initState();

  _userState = const context.read<UserCubit>().state();
  print("I am inside the initState The value of userstate is ${_userState.userModel}");  // This prints null , but why ?
  if (_userState.userModel != null) {
    print("user is ${_userState.userModel.toString()}");
  }
}
