SliverAlignedGrid class
A sliver that places multiple box children in a two dimensional arrangement.
SliverAlignedGrid places its children in a grid where each track has the main axis extent of the widest child. Each child is stretched to match the track main axis extent.

Constructors
- SliverAlignedGrid({Key? key, required NullableIndexedWidgetBuilder itemBuilder, int? itemCount, required SliverSimpleGridDelegate gridDelegate, double mainAxisSpacing = 0, double crossAxisSpacing = 0, bool addAutomaticKeepAlives = true, bool addRepaintBoundaries = true})
-
Creates a custom SliverAlignedGrid.
const
- SliverAlignedGrid.count({Key? key, required NullableIndexedWidgetBuilder itemBuilder, int? itemCount, required int crossAxisCount, double mainAxisSpacing = 0, double crossAxisSpacing = 0, bool addAutomaticKeepAlives = true, bool addRepaintBoundaries = true})
- Creates a sliver that places multiple box children in an aligned arrangement with a fixed number of tiles in the cross axis.
- SliverAlignedGrid.extent({Key? key, required NullableIndexedWidgetBuilder itemBuilder, int? itemCount, required double maxCrossAxisExtent, double mainAxisSpacing = 0, double crossAxisSpacing = 0, bool addAutomaticKeepAlives = true, bool addRepaintBoundaries = true})
- Creates a sliver that places multiple box children in an aligned arrangement with tiles that each have a maximum cross-axis extent.
