Hi everyone. I have a `MutableStateFlow` and I need to know when collectors subscribe/unsubscribe to/from this flow.
I see the `fun SharedFlow&lt;T&gt;.onSubscription` extension which invokes the callback when the flow starts to be collected but I can’t find any extension function to know when a collector cancels the subscription.
I’m basically looking for the equivalent of RxJava <http://reactivex.io/RxJava/3.x/javadoc/io/reactivex/rxjava3/core/Observable.html#doOnSubscribe-io.reactivex.rxjava3.functions.Consumer-|doOnSubscribe> and <http://reactivex.io/RxJava/3.x/javadoc/io/reactivex/rxjava3/core/Observable.html#doOnDispose-io.reactivex.rxjava3.functions.Action-|doOnDispose>.
Does anyone know if there is a way to know when a collector cancels its subscription?

looks like what I’m looking for is the `onCompletion` extension function…

IMHO i dont think flow can be `unsubscribe` except cancel the subscribe coroutine, correct me if i'm wrong
