ReorderableGridState class

The state for a grid that allows the user to interactively reorder the grid items.

An app that needs to start a new item drag or cancel an existing one can refer to the ReorderableGrid's state with a global key:

GlobalKey<ReorderableGridState> gridKey = GlobalKey<ReorderableGridState>();
...
ReorderableGrid(key: gridKey, ...);
...
gridKey.currentState.cancelReorder();
