up method Null safety
- {Duration timeStamp = Duration.zero}
Create a PointerUpEvent.
By default, the time stamp on the event is Duration.zero. You can give a
specific time stamp by passing the timeStamp
argument.
The object is no longer usable after this method has been called.
Implementation
PointerUpEvent up({ Duration timeStamp = Duration.zero }) {
assert(!isPanZoomActive);
assert(isDown);
_isDown = false;
return PointerUpEvent(
timeStamp: timeStamp,
kind: kind,
device: _device,
pointer: pointer,
position: location!,
);
}
