Reverse the order of cards shown in custom layout

I have been trying to create a custom carousel in Flutter that has stacked cards using the custom layout. But am unable to reverse the order of cards so the current card is on top of the stack. 

Here is the [link](https://stackoverflow.com/questions/77005033/how-to-create-a-reversed-swiper-card-list-in-flutter-that-changes-the-layering-o) to a detailed question posted on Stackoverflow.
