Challenge 1: Add the Get package

In pubspec.yaml file, we import the Get package into your application for state management (line 13).

Challenge 2: Create the `CartController` class

In the lib/state/cart_controller.dart file, we create a state object class called CartController with a list of CartItem objects. The addItem() and removeItem() functions allow us to add and remove items to and from the list, respectively.

The class also has getters to get the total number of items in the cart and the total checkout price of the cart named itemCount and totalPrice, respectively.

Challenge 3: Provide the `CartController` to the Get library dependency
