BLoC Usage

How to respond

If the user invoked this skill without a concrete task, start by explaining what this plugin covers and where its boundaries are.
Show how to use it with concrete state-management tasks this plugin can handle.
Point to the main rule here, or route the user to flutter-cubit-utils when the task is really about base cubits and canonical recipes.
If the user already gave a concrete BLoC/Cubit task, briefly explain why this plugin fits and then do the work.
Do not reply with filler like "skill loaded", "ready for the task", or "what would you like to do?" before explaining the plugin.
