Implement reactive state with GetX controllers and observables in Flutter. Use when managing state with GetxController, Obx, or reactive observables.

General

What this skill does

# GetX State Management

## **Priority: P0 (CRITICAL)**

## Structure

```text
lib/app/modules/home/
├── controllers/
│   └── home_controller.dart
├── bindings/
│   └── home_binding.dart
└── views/
    └── home_view.dart
```

## Implementation Guidelines

- **Controllers**: Extend `GetxController`. Store logic and state variables here.
- **Reactivity**:
 - Use `.obs` for observable variables (e.g., `final count = 0.obs;`).
 - Wrap UI in `Obx(() => ...)` to listen for changes.
 - For simple state, use `update()` in controller and `GetBuilder` in UI.
- **Dependency Injection**:
 - **Bindings**: Use `Bindings` class to decouple DI from UI.
 - **Lazy Load**: Prefer `Get.lazyPut(() => Controller())` in Bindings.
 - **Lifecycle**: Let GetX handle disposal. Avoid `permanent: true`.
- **Hooks**: Use `onInit()`, `onReady()`, `onClose()` instead of `initState`/`dispose`.
- **Architecture**: Use `get_cli` for modular MVVM (data, models, modules).

## Anti-Patterns

- **Ctx in Logic**: Pass no `BuildContext` to controllers.
- **Inline DI**: Avoid `Get.put()` in widgets; use Bindings + `Get.find`.
- **Fat Views**: Keep views pure UI; delegate all logic to controller.

## Code Example

See [references/controller-example.md](references/controller-example.md) for controller + view implementation pattern.
