and I also used a single child scroll view and column so that I can show my cards in that column of draggableScrollableSheet. But I want draggableScrollableSheet to take height dynamically instead of defining size. Like now I want to show only 2 to 3 cards and that is taking full screen. But I want it to take the minimum height of the screen. How can we achieve this?

Flexible and scrollable bottom sheet. All you have to do is call showFlexibleBottomSheet() and you'll get a popup that looks like a modal bottom sheet and can be resized by dragging it up and down and scrolled when expanded.
A scroll controller creates a ScrollPosition to manage the state specific to an individual Scrollable widget. To use a custom ScrollPosition, subclass ScrollController and override createScrollPosition. A ScrollController is a Listenable.
I was struggling with this for a while, and then discovered that the correct way to achieve this is to use ClampingScrollPhysics as the physics parameter of the scroll view.
