Is there any way to get a Sharable Flow that ends? I have a slow producer with an end. And I have multiple slow consumers that need all the produced items. My current solution is convert that Flow in a List and then start the consumers. But I'm losing time because some consumers can start it's work as soon as the producer emits the first element.

Catch the upstream completion with
onComplete { … }
and emit a special value downstream that signals the end of the stream. Downstream you can use
.takeWhile {}
to stop the downstream flow if the shared flow has emitted the special value.
