SliverGridDelegateWithMaxCrossAxisExtent class Null safety

Creates grid layouts with tiles that each have a maximum cross-axis extent.

This delegate will select a cross-axis extent for the tiles that is as large as possible subject to the following conditions:

  • The extent evenly divides the cross-axis extent of the grid.
  • The extent is at most maxCrossAxisExtent.

For example, if the grid is vertical, the grid is 500.0 pixels wide, and maxCrossAxisExtent is 150.0, this delegate will create a grid with 4 columns that are 125.0 pixels wide.

This delegate creates grids with equally sized and spaced tiles.
