<itemvalue="A widget that calls callbacks in response to common pointer events. It listens to events that can construct gestures, such as when the pointer is pressed, moved, then released or canceled. It does not listen to events that are exclusive to mouse, such as when the mouse enters, exits or hovers a region without pressing any buttons. For these events, use [MouseRegion]. Rather than listening for raw pointer events, consider listening for higher-level gestures using [GestureDetector]."/>

It is an error to call [setState] unless [mounted] is true."/>
<itemvalue="Whether the [Widget] this context is associated with is currently mounted in the widget tree. Accessing the properties of the [BuildContext] or calling any methods on it is only valid while mounted is true. If mounted is false, assertions will trigger.

<itemvalue="A widget that tracks the movement of mice. {@youtube 560 315 https:www.youtube.comwatch?v=1oF3pI5umck} [MouseRegion] is used when it is needed to compare the list of objects that a mouse pointer is hovering over between this frame and the last frame. This means entering events, exiting events, and mouse cursors. To listen to general pointer events, use [Listener], or more preferably, [GestureDetector]."/>

<itemvalue="If true: on desktop platforms, a drag handle is stacked over the center of each item's trailing edge; on mobile platforms, a long press anywhere on the item starts a drag.

On mobile platforms, the entire item is wrapped with a [ReorderableDelayedDragStartListener]. To change the appearance or the layout of the drag handles, make this parameter false and wrap each list item, or a widget within each list item, with [ReorderableDragStartListener] or [ReorderableDelayedDragStartListener], or a custom subclass of [ReorderableDragStartListener].
