SwipeableStack : How can i rewind once the cards are swiped

Hello All,
FlutterFlow SwipeableStack does not expose the rewind action on the controller, it only allows the L, R, T, B swipe controls. I have a requirement in my project to rewind the stack once the cards are all swiped.
Any ideas on how i can achieve this. I tried to define a custom action on SwipeableStack but could not get far enough.

Thanks in Advance for any help.
