handleEvent method
- @override
override
Override this method to handle pointer events that hit this render object.
For RenderBox objects, the entry argument is a BoxHitTestEntry. From this
object you can determine the PointerDownEvent's position in local coordinates.
(This is useful because PointerEvent.position is in global coordinates.)
If you override this, consider calling debugHandleEvent as follows, so that you can support debugPaintPointersEnabled:
@override
void handleEvent(PointerEvent event, HitTestEntry entry) {
assert(debugHandleEvent(event, entry));
// ... handle the event ...
}
Implementation
@override
void handleEvent(PointerEvent event, BoxHitTestEntry entry) {
assert(debugHandleEvent(event, entry));
if (event is PointerDownEvent && isInteractive)
_tap.addPointer(event);
}
