I have a Tinderlike card deck. I'm trying to get the front card of the deck from outside the Tinderlike widget (Stateful).

When I try to expose his state using controlling state from outside of a StatefulWidget

I always get a null. My TinderLike widget is inside a StatelessWidget. Is there a better way to expose data from a StatefulWidget to its parents?

What do you mean by "always null"? – Rémi Rousselet Oct 02 '18 at 15:03
when im invoking using TinderLike.of(context).getFrontCard() a NoSuchMethodError: The method 'getFrontCard' was called on null is always thrown – user2953680 Oct 02 '18 at 15:05
Could you provide the codes you're using? – dshukertjr Oct 02 '18 at 15:10
its a part of a big project so it will be problematic :( – user2953680 Oct 02 '18 at 15:29
