Are you sure this is working? I put a dynamic number in totalNum and used a button to change it, but the number of cards remains the same.

That example doesn't really make it async, it just inserts in the List instead of adding. You already need to have a list with a predetermined size.

If I'm going to fetch data from a database and then add it to the list, it doesn't work. Once you give the totalNum a certain int, it doesn't change anymore.

What I did, and recommend you guys to do it too, is to make a FutureBuilder that can fetch all the data that you need and create the list (of widgets, string, or whatever it is) in a LoadingPage, then store that list in a file (like "userProfiles.dart") and then in the page that you want to use this package, in the totalNum, you can use the list.length, and in the cardBuilder the list[index].

I changed the library code and put a setstate inside the didUpdateWidget method, and it works with a dynamically updating list.

@singhayush1403 What exactly did you do? Can you please share the snippet?

I think @vip20 is talking about this Pull Request. I used it, and yes I can re-add/load more cards by adding more items to my list.

However what I was unable to do with this package at all is to NOT to reset the index after loading the list. I don't want to display all the list again when I load it, because when user swipes a card (left or right), this means that that card is already used and I don't want to display it again.

I even tried to remove the swiped card from my list, however the card displayed to user won't be keep the same after loading new cards, it will move to another one (where the index pointer is). Yet you can't control the index.

It'd be a great help of anyone let us know how to do that.

I was able to add to list and not to reset index after rebuild. Actually its resets but im removing items after I swipe them and send new stream to builder. #50 I created pr you can check that out.
