onLongPress property
final
Called when a long press gesture with a primary button has been recognized.
Triggered when a pointer has remained in contact with the screen at the same location for a long period of time.
This is equivalent to (and is called immediately after) onLongPressStart. The only difference between the two is that this callback does not contain details of the position at which the pointer initially contacted the screen.
See also:
- kPrimaryButton, the button this callback responds to.
- LongPressGestureRecognizer.onLongPress, which exposes this callback at the gesture layer.
Implementation
final GestureLongPressCallback? onLongPress;
