well, I think the kotlin compiler inference can resolve it for you

I can only return something like a

Pair

from

combine

but I want a Flow that emits each value separately as its supertype

Before asking here, did you look at the KDoc of

combine

? I'm aksing to understand your thought process, and see if the doc should mention the

merge

operator to help folks in the future.

I thought I'll have to use combine but I didn't know with what transform block

I will google more thoroughly next time

the concept of Flow transformation operators are pretty the same thing

looks like

combine

was actually the correct operator, because with

merge

I don't get all the values into a single Flow

I just get separate emits from both Flows

instead I now merge the 2 lists inside the combine operator like this:

val combinedChatFlow: Flow<List<Chat>> = combine(directChatsFlow, groupChatsFlow) { directChats, groupChats ->
    directChats + groupChats
}
