Agent-skills-standard flutter-getx-state-management

Implement reactive state with GetX controllers and observables in Flutter. Use when managing reactive state with GetX controllers or observables in Flutter. (triggers: **_controller.dart, **/bindings/*.dart, GetxController, Obx, GetBuilder, .obs, Get.put, Get.find, Get.lazyPut)

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
