Is there a reason why combine flow would not emit end result?

val x = combine(y.invoke(), z.invoke()){ y+z }

Both y and z are flows of same type and they seem to not throw any errors.

You still have to collect that flow, combine returns just a cold transformed flow, it's not terminal operator

[K Merle]

I am doing that with collectAsState(initial = null) but it keeps returning null, altho both y and z contain values. It's just that transform is never called.

combine is probably causing a new flow to get instantiated at each composition. Try moving the combine outside the composable so that all you do here is collect it

[K Merle]

It seems that nested .transformLatest that is inside flow y causes an issue. Maybe I do not understand it enough, but changing to flow builder and emitting value solves an issue.

If you have a viewmodel do the combine there and expose the result
