SliverWaterfallFlow.count constructor

SliverWaterfallFlow.count({
  1. Key? key,
  2. required int crossAxisCount,
  3. double mainAxisSpacing = 0.0,
  4. double crossAxisSpacing = 0.0,
  5. List<Widget> children = const <Widget>[],
  6. LastChildLayoutTypeBuilder? lastChildLayoutTypeBuilder,
  7. CollectGarbage? collectGarbage,
  8. ViewportBuilder? viewportBuilder,
  9. bool closeToTrailing = false,
})

Creates a sliver that places multiple box children in a two dimensional arrangement and masonry layout with a fixed number of tiles in the cross axis.

Uses a SliverWaterfallFlowDelegate as the gridDelegate, and a SliverChildListDelegate as the delegate.
