SliverReorderableListState class Null safety

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

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

GlobalKey<SliverReorderableListState> listKey = GlobalKey<SliverReorderableListState>();
...
SliverReorderableList(key: listKey, ...);
...
listKey.currentState.cancelReorder();

ReorderableDragStartListener and ReorderableDelayedDragStartListener refer to their SliverReorderableList with the static SliverReorderableList.of method.
