CustomPaginatedGridView<T> class

A customizable grid view with pagination capabilities.

This widget displays items in a grid and automatically handles loading more items when the user scrolls to the bottom. It also supports pull-to-refresh.

Type parameter T is the type of the data items in the grid, although it's not directly used in the properties of this class, it's passed to the _CustomPaginatedGridViewState to maintain type consistency.
