bloc
Use when creating a Cubit or Bloc, modeling state with sealed classes or status enums, wiring BlocBuilder/BlocListener/BlocProvider, writing bloc tests, or choosing between Cubit and Bloc.
npx skills add evanca/flutter-ai-rules --skill bloc --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.

# Bloc Skill Design, implement, and test state management using the [bloc](https://pub.dev/packages/bloc) and [flutter_bloc](https://pub.dev/packages/flutter_bloc) libraries. ## When to Use Use this skill when: * Creating a new Cubit or Bloc for a feature. * Modeling state (choosing between sealed classes and a single state class with status enum). * Wiring `BlocBuilder`, `BlocListener`, `BlocConsumer`, or `BlocProvider` in the widget tree. * Writing unit tests for a Cubit or Bloc. * Deciding between Cubit and Bloc. * Refactoring existing state management to follow bloc conventions. --- ## 1. Cubit vs Bloc | Situation | Use | |---|---| | Simple state, no events needed | `Cubit` | | Complex flows, event traceability needed | `Bloc` | | Advanced event processing (debounce, throttle) | `Bloc` with event transformers | **Default to `Cubit`. Refactor to `Bloc` only when requirements grow.** --- ## 2. Naming Conventions ### Events (Bloc only) - Named in **past tense**: `LoginButtonPressed`, `UserProfileLoaded`. - Format: `BlocSubject` + optional noun + verb. - Initial load event: `BlocSubjectStarted` (e.g., `AuthenticationStarted`). - Base event class: `BlocSubjectEvent`. ### States - Na

What does the bloc skill do?
Use when creating a Cubit or Bloc, modeling state with sealed classes or status enums, wiring BlocBuilder/BlocListener/BlocProvider, writing bloc tests, or choosing between Cubit and Bloc.
How do I install it?
Run `npx skills add evanca/flutter-ai-rules --skill bloc --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From evanca/flutter-ai-rules, a repository with 604 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
