SelectedItemAnchor.START gets stuck on last item

[lukepighetti]

package tries to animate to second to last, but it really needs to switch to SelectedItemAnchor.END when at the last item

gets-stuck-on-last-item.mp4

this is a quick fix i came up with

                      listViewPadding: EdgeInsets.symmetric(horizontal: 24) +
                          // https://github.com/MSVCode/scroll_snap_list/issues/39
                          EdgeInsets.only(
                            right: _shim(
                              MovementCard.width,
                              24,
                              MediaQuery.sizeOf(context).width,
                            ),
                          ),

double _shim(double cardWidth, double horizontalPadding, double viewportWidth) {
  return viewportWidth - cardWidth - horizontalPadding;
}
