resetActivity method

  1. @override
void resetActivity ()
override

Called by the ScrollActivityDelegate when it has changed type (for example, when changing from an Android-style scroll position to an iOS-style scroll position). If this activity can differ between the two modes, then it should tell the position to restart that activity appropriately.

For example, BallisticScrollActivity's implementation calls ScrollActivityDelegate.goBallistic.

Implementation 

@override
void resetActivity() {
  delegate.goBallistic(velocity);
}
