onLongPressUp property Null safety
read / write
Called when the pointer stops contacting the screen after a long-press by a primary button.
This is equivalent to (and is called immediately after) onLongPressEnd. The only difference between the two is that this callback does not contain details of the state of the pointer when it stopped contacting the screen.
