Is there anyway I can display all the contents of a Stack widget which has a List of dynamically created Positioned widgets as its children?

Here is my code for build method,

Widget build(BuildContext context) {
return Scaffold(
  appBar: AppBar(
    title: Text('Game Screen'),
  ),
  body: Column(
    children: [
      Expanded(
        //widget 1..
      ),
      Expanded(
        //widget 2..
      ),
      Expanded(
        flex: 3,
        child: Stack(         // Problem is with this stack widget
          children: cardList, // dynamically generated list of Positioned Widgets.
        ),
      ),
    ],
  ),
);}

I tried enclosing this Stack Widget inside FittedBox widget. Hoping, that it would scale the contents of the Stack but sadly it gives an error saying that "The child of FittedBox should be Finite Sized". But my stack is displaying a dynamically generated list of Positioned Widgets so it could not be finite sized. Any workaround this?

P.S. I dont want to use List View, I want to scale the contents of the stack.. Just like how we witness it when using FittedBox Widget.
