  19. ScrollViewKeyboardDismissBehavior keyboardDismissBehavior = ScrollViewKeyboardDismissBehavior.manual,
  20. String? restorationId,
  21. Clip clipBehavior = Clip.hardEdge,
})

Creates a scrollable, 2D array of widgets with a fixed number of tiles in the cross axis.

Uses a SliverSimpleGridDelegateWithFixedCrossAxisCount as the gridDelegate.

The addAutomaticKeepAlives argument corresponds to the SliverChildListDelegate.addAutomaticKeepAlives property. The addRepaintBoundaries argument corresponds to the SliverChildListDelegate.addRepaintBoundaries property.
