onSecondaryLongPressUp property Null safety
final
A pointer that has triggered a long-press with a secondary button has stopped contacting the screen.
This is equivalent to (and is called immediately after) onSecondaryLongPressEnd. 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.
See also:
- kSecondaryButton, the button this callback responds to.
- LongPressGestureRecognizer.onSecondaryLongPressUp, which exposes this callback at the gesture layer.
Implementation
final GestureLongPressUpCallback? onSecondaryLongPressUp;
