How to provide context to BlocProvider.of without using BlocBuilder in flutter bloc

Question

This is my BlocProvider portion of code:

late BuildContext _context;
@override
  Widget build(BuildContext context) {
    final _formKey = GlobalKey<FormState>();

    return BlocProvider<AccountBloc>(
      create: (context) {
        _context = context;
        return AccountBloc();
      },
      child: Scaffold(

And inside the onPressed I use this.context:

BlocProvider.of<AccountBloc>(this._context)..add(AddAccountEvent(account: account));

When I run it the error says:

LateInitializationError: Field '_context@30149156' has not been initialized.

Solution

remove late BuildContext _context; and wrap your scaffold inside a Builder widget. so the provided context is an updated context and you can simply use BlocProvider.of<AccountBloc>(context)..add(AddAccountEvent(account: account));

Don't mind the _formKey sir, I used it in a form. Using a Builder will work. But it's the same as using BlocBuilder. Is there a way to use BlocProvider.of<Bloc>(context)..add(BlocEvent()) without using Builder or BlocBuilder? Thank you.

i mean remove late BuildContext _context; sorry. you can move your scaffold in a separate widget. there is no way else. by the way, what is the problem with Builder?

Sorry, I thought Builder is the same in BlocBuilder. The reason I don't want to use BlocBuilder because It's main use is when you want to access the state of a bloc.
