@sagarbhojaviya Any leads on this issue?

sagarbhojaviya commented 2 years ago

No

Shvet commented 2 years ago

I am getting this error too.

ItayFeld commented 2 years ago

Are you guys holding the StackView as an item inside a RecyclerView and removing it once the cards are all swiped?

sagarbhojaviya commented 2 years ago

We removing card once swipe

Shvet commented 2 years ago

I think it is already coded in CardStackLayoutManager for removing it.

ItayFeld commented 2 years ago

Yap, every card that is swiped is being removed but once all cards are swiped, do you delete the StackView from an adapter or something or is it just a stand alone view?

sagarbhojaviya commented 2 years ago

If you are swiping card very fast than chances to crash by this error

ItayFeld commented 2 years ago

Any card or just the last one?

sagarbhojaviya commented 2 years ago

it just a stand alone view

sagarbhojaviya commented 2 years ago

Any card or just the last one?

Yap, it's the same crash I'm seeing in the Crashlytics but can't manage to reproduce it myself for testing solutions.
