However, in some cases, we may wish to create new instances to maintain separate states of the same class. This is when Get.create comes into the picture. When we initialize a dependency using Get.create, a new instance of the dependency is created every time Get.find is called.

This feature becomes instrumental when we have a page with multiple widgets that use the same controller but do not share the same state of the controller. For example, a shopping cart page:

Press + to interact
class ShoppingController extends GetxController {
  RxInt quantity = 0.obs;
  RxInt total = 0.obs;
}
