Looks like

ReceiveChannel.last()

is deprecated, it links to https://github.com/Kotlin/kotlinx.coroutines/issues/254 but what do I actually have to replace it by?

How is your

ReceiveChannel

being created? You might be able to replace it with

Flow

. (Although you'd be moving from deprecated warnings to some experimental warnings lol).

It's basically a bunch of objects that have an input and an output channel and they're connected in a cyclic graph, and I want to get the last output of one of them.

Hmm, cycle, sounds naughty.... I guess you could do

.consumeAsFlow().last()

.

Sounds like the amplifier problem for aoc =)

What a coincidence 🙂
