[Assistance] elements inside card not clickable

[Shubxam]

I tried placing stateful elements inside _itemBuilder widget, but I couldn't get them to work. E.g how do you place a button inside the widget and make it clickable

One of the easiest ways to get what you want is to fork and change the widget returned by the build method of _StackCardState class to the following:

    return Stack(fit: StackFit.expand, children: <Widget>[
      PageView.builder(
        onPageChanged: widget.onSwap,
        physics: BouncingScrollPhysics(),
        controller: _pageController,
        itemCount: widget.itemCount,
        itemBuilder: (context, index) {
          return Container();
        },
      ),_cardStack(),
      widget.displayIndicator ? _cardIndicator() : Container(),

However, while this method is easy, it has the disadvantage that you will not be able to swipe on the card.

Currently, the transparent container created by PageView class is placed on top of your button.
Therefore, the button on your card will not work.
