Add support for `always_use_package_imports` about dartbarrelfilegenerator

[mikededo]

Hi @mbfakourii 👋🏼! Thanks for opening an issue. I have stopped using Dart and I'm no longer familiarised with the linter. However, from what I understand about this rule, would consist on adding package:{packageName} as a prefix of the import, right?

Should this only work for the root barrel file? I mean, should this package:{packageName} prefix be added for a barrel file that is, for example, 3 folders deep? Or it should only be added to the top of the folder? Also, I would have to somehow get the packageName from the pubspec.yaml file, somehow, and I'm not really sure if that would be possible.

Nonetheless, I see that the linter has a quick fix for this issue, so if it is a bit of a mess to develop, I would suggest running the linter (maybe I can run it using VSCode's API) in order to fix it.

This is solved with the v6.2.0. You simply have to enable the option: dartBarrelFileGenerator.prependPackageToLibExport.

Quick fix does not work for this rule

An example of the code I mean is as follows

export 'package:myapp/core/bloc/checkout/checkout_bloc.dart';
export 'package:myapp/core/bloc/transaction/transaction_bloc.dart';
export 'package:myapp/core/config/config.dart';
export 'package:myapp/core/config/constants.dart';
export 'package:myapp/core/intl/generated/l10n.dart';
export 'package:myapp/core/model/enums/legal_status.dart';

This structure replaces the structure like below

export '../core/bloc/checkout/checkout_bloc.dart';
export '../core/bloc/transaction/transaction_bloc.dart';
export '../core/config/config.dart';
export '../core/config/constants.dart';
export '../core/intl/generated/l10n.dart';
export '../core/model/enums/legal_status.dart';

So I understand this would ONLY happen for the barrel file that is at the root of the project, this being ./lib/<filename>.dart, right?

Sorry for the delay. Currently I'm a bit tight on time and can barely work on the weekends. I'm working on it.
