Possibility to get index of card through controller

[samdasse]

I can create buttons that interact with the card swiper widget but i can't create a button that gets the index of the card and lets you get the card information from that index.
Is it already possible to do so with the controller without using external variables?

Currently, this is not possible, what kind of information would you like to have? Card positions or something else?
