PlatformSelectableRegionContextMenu class

A widget that provides native selection context menu for its child subtree.

This widget currently only supports Flutter web. Using this widget in non-web platforms will throw UnimplementedErrors.

In web platform, this widget registers a singleton platform view, i.e. a HTML DOM element. The created platform view will be shared between all PlatformSelectableRegionContextMenus.

Only one SelectionContainerDelegate can attach to the PlatformSelectableRegionContextMenu at a time. Use attach method to make a SelectionContainerDelegate to be the active client.
