dispose method
- @override
override
Releases any resources used by the object.
This method is called by the owner of this gesture recognizer when the object is no longer needed (e.g. when a gesture recognizer is being unregistered from a GestureDetector, the GestureDetector widget calls this method).
Implementation
@override
void dispose() {
final List<_TapGesture> localGestures = List<_TapGesture>.from(_gestureMap.values);
for (_TapGesture gesture in localGestures)
gesture.cancel();
// Rejection of each gesture should cause it to be removed from our map
assert(_gestureMap.isEmpty);
super.dispose();
}
