GridView.custom constructor

const GridView.custom({Key key, Axis scrollDirection: Axis.vertical, bool reverse: false, ScrollController controller, bool primary, ScrollPhysics physics, bool shrinkWrap: false, EdgeInsetsGeometry padding, @required SliverGridDelegate gridDelegate, @required SliverChildDelegate childrenDelegate, double cacheExtent, int semanticChildCount })

Creates a scrollable, 2D array of widgets with both a custom SliverGridDelegate and a custom SliverChildDelegate.

To use an IndexedWidgetBuilder callback to build children, either use a SliverChildBuilderDelegate or use the GridView.builder constructor.

The gridDelegate and childrenDelegate arguments must not be null.

Implementation 

const GridView.custom({
  Key key,
  Axis scrollDirection = Axis.vertical,
  bool reverse = false,
  ScrollController controller,
  bool primary,
  ScrollPhysics physics,
  bool shrinkWrap = false,
  EdgeInsetsGeometry padding,
  @required this.gridDelegate,
  @required this.childrenDelegate,
  double cacheExtent,
  int semanticChildCount,
}) : assert(gridDelegate != null),
     assert(childrenDelegate != null),
     super(
       key: key,
       scrollDirection: scrollDirection,
       reverse: reverse,
       controller: controller,
       primary: primary,
       physics: physics,
       shrinkWrap: shrinkWrap,
       padding: padding,
       cacheExtent: cacheExtent,
       semanticChildCount: semanticChildCount,
     );
