Skillshub flutter-getx-state-management

Simple and powerful reactive state management using GetX. 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

class UserController extends GetxController {
  final name = "User".obs;
  void updateName(String val) => name.value = val;
}

class UserView extends GetView<UserController> {
  @override
  Widget build(ctx) => Scaffold(
    body: Obx(() => Text(controller.name.value)),
    floatingActionButton: FloatingActionButton(
      onPressed: () => controller.updateName("New"),
    ),
  );
}
