GetX Throwing TypeError when try to build with Obx

Question

I have controller call MenuController

class MenuController extends GetxController {
  var currentCategory = Rx<int>(0);
  @override
  void onReady() async {
    await Future.delayed(const Duration(milliseconds: 2000));
  }

  void setMenuByIndex(int index) {
    currentCategory.value = index;
  }
}

And I'm trying to check selected index from simple Widget like this

Obx(() => Text(controller.currentCategory.value.toString()))

Getting controller like here

final controller = Get.find<MenuController>();

Im getting the error

type 'int' is not a subtype of type 'Rx<int>' of 'function result'

Answer 1

try this...

 class MenuController extends GetxController {
  Rx<int> currentCategory = Rx<int>(0);
  @override
  void onReady() async {
    await Future.delayed(const Duration(milliseconds: 2000));
  }

  void setMenuByIndex(int index) {
    currentCategory.value = index;
  }
}
