pointerScroll abstract method
- double delta
Changes the scrolling position based on a pointer signal from current value to delta without animation and without checking if new value is in range, taking min/max scroll extent into account.
Any active animation is canceled. If the user is currently scrolling, that action is canceled.
This method dispatches the start/update/end sequence of scrolling notifications.
This method is very similar to jumpTo, but pointerScroll will update the ScrollDirection.
Implementation
void pointerScroll(double delta);
