<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]."/>
