onTertiaryLongPressUp property Null safety

GestureLongPressUpCallback? onTertiaryLongPressUp
read / write

Called when the pointer stops contacting the screen after a long-press by a tertiary button.

This is equivalent to (and is called immediately after) onTertiaryLongPressEnd. 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.
