To refactor the implementation, we can create a custom view (or custom control).

Custom views can be built by combining existing controls, deriving from base classes like View, ViewCell, or ContentView, and overriding specific methods to customize rendering or behavior.
To create a custom view that can be reused in both ItemsPage and ItemDetailPage, we should first create a new folder called Templates within the Views directory. In Visual Studio, we can right-click on the Templates folder...
