SliverReorderableGridDelegateWithFixedCrossAxisCount class

Creates grid layouts with a fixed number of tiles in the cross axis.

For example, if the grid is vertical, this delegate will create a layout with a fixed number of columns. If the grid is horizontal, this delegate will create a layout with a fixed number of rows.

This delegate creates grids with equally sized and spaced tiles.
