Response State Builder

Why?

If you're using the Flutter Bloc library, you may notice that there's some coupling between your view and the library code. BlocBuilder, BlocListener, etc may cause a lot of trouble to you if the library gets deprecated. Thinking in this problem, I've created the ResponseStateBuilder and ActionHandler.

ReponseStateBuilder

It receives a BLoC and returns 3 callbacks. Loading(optional), error and Success. If the BLoC library gets deprecated, all you have to do is change the bloc parameter and all your view logic will not be affected.

ActionHandler

It receives a BLoC as parameter and returns a callback. This callback is used in "actions", things that should happen without changing the page state (for example, navigating to another page, or showing a dialog).

How to use it

You need to create an interface called "WhateverNameYouWant" and your states / actions should inherit from it. There's an usage example in the main.dart file.
