10/18/2021, 9:22 PMHi, using Compose and Paging, is there a way to mutate the items? A normal use case is to have a list of items (paginated) where you can toggle a button on each item. E.g. follow/unfollow. In a non-compose setting I'd just update the reactive stream and react accordingly, but since Paging is wrapping the source, I'm unable to mutate. Is there another approach for this, or does the paging library simply only work with immutable data?

10/19/2021, 7:53 AMHi, Csaba. Thanks for helping. I somehow missed the map operator for PagingData. I’m looking into it now. I’ll see if I can make a contrived example a bit later. The problem with invalidating the whole Pager is that everything invalidates. Not just the single item.
