Creates a scrollable, 2D array of widgets whose size is variable in the main axis with both a custom SliverGridDelegate and a custom SliverChildDelegate.
To use an IndexedWidgetBuilder callback to build children, either use a SliverChildBuilderDelegate or use the WaterfallFlow.builder constructor.
The gridDelegate
and childrenDelegate
arguments must not be null.
