I am not able to access TextEditingController using bloc in Flutter - flutter

Question

How to access TextEditingController(); using bloc . here my code :-
after i use
BlocProvider.of<UsernameupdateCubit>(context).nameUpdate(userUpdateController.text);
I got an error which is
BlocProvider.of() called with a context that does not contain a UsernameupdateCubit.
Please check :
I use
final userUpdateController = TextEditingController();
then
TextFormField(
controller: userUpdateController,
decoration: InputDecoration(
labelText: "Full Name",
border: OutlineInputBorder(),
prefixIcon: Icon(FeatherIcons.user, size: 24),
),
),
after that use a button to save/sent/access anywhere or display in list view :
button is :
Container(
margin: EdgeInsets.only(top: 10),
alignment: AlignmentDirectional.centerEnd,
child: ElevatedButton(
style: ElevatedButton.styleFrom(
elevation: 1,
primary: Color(0xff34495e),
),
onPressed: () {
// BlocProvider.of<UsernameupdateCubit>(context).nameUpdate();
// BlocProvider.of<WeatherBloc>(context)
BlocProvider.of<UsernameupdateCubit>(context)
.nameUpdate(userUpdateController.text);
},
child: Text(
"Continue",
),
),
),
My Cubit :
class UsernameupdateCubit extends Cubit<UsernameupdateState> {
UsernameupdateCubit() : super(UsernameupdateState(userUpdateName: ''));
void nameUpdate(userUpdateController) =>
emit(UsernameupdateState(userUpdateName: userUpdateController.text));
}
and state is :
class UsernameupdateState {
String userUpdateName;
UsernameupdateState({
required this.userUpdateName,
});
}

Answer 1

all are same but I include BlocProvider in :
using multibloc:
BlocProvider(
create: (context) => UsernameupdateCubit(),
),
after that I changed my cubit :
void nameUpdate(userUpdateController) =>
emit(UsernameupdateState(userUpdateName: userUpdateController));
and yes that's it .
