SliverGridRegularTileLayout class
A SliverGridLayout that uses equally sized and spaced tiles.
Rather that providing a grid with a SliverGridLayout directly, you instead provide the grid a SliverGridDelegate, which can compute a SliverGridLayout given the current SliverConstraints.
This layout is used by SliverGridDelegateWithFixedCrossAxisCount and SliverGridDelegateWithMaxCrossAxisExtent.
See also:
- SliverGridDelegateWithFixedCrossAxisCount, which uses this layout.
- SliverGridDelegateWithMaxCrossAxisExtent, which uses this layout.
- SliverGridLayout, which represents an arbitrary tile layout.
- SliverGridGeometry, which represents the size and position of a single tile in a grid.
- SliverGridDelegate.getLayout, which returns this object to describe the delegate's layout.
- RenderSliverGrid, which uses this class during its RenderSliverGrid.performLayout method.
