GetX State Management

GetX is a lightweight, all-in-one package for Flutter state management, dependency injection, and routing. It uses reactive variables (.obs) that notify listeners when values change. State logic lives in GetxControllers (classes extending GetxController). GetX automatically rebuilds widgets that listen to changed observables. Key features: (1) Reactive variables (int.obs, String.obs, List.obs), (2) GetxControllers for business logic, (3) Get.put/Get.find for dependency injection, (4) Get.to/Get.toNamed for routing, (5) Obx widget for rebuilding on state change. Minimal boilerplate compared to Provider or BLoC.
