@Override
public void onStopNestedScroll(
    CoordinatorLayout coordinatorLayout, @NonNull T abl, View target, int type) {
  // onStartNestedScroll for a fling will happen before onStopNestedScroll for the scroll. This
  // isn't necessarily guaranteed yet, but it should be in the future. We use this to our
  // advantage to check if a fling (ViewCompat.TYPE_NON_TOUCH) will start after the touch scroll
  // (ViewCompat.TYPE_TOUCH) ends
  if (lastStartedType == ViewCompat.TYPE_TOUCH || type == ViewCompat.TYPE_NON_TOUCH) {
    // If we haven't been flung, or a fling is ending
    snapToChildIfNeeded(coordinatorLayout, abl);
    if (abl.isLiftOnScroll()) {
      abl.setLiftedState(abl.shouldLift(target));
    }
  }

  // Keep a reference to the previous nested scrolling child
  lastNestedScrollingChildRef = new WeakReference<>(target);
