How to convert pass Observable emissions to MutableSharedFlow<T> ?

[wasyl]

What would you expect such flow emits? Whatever the upstream flow emits + whatever is pushed to the MutableSharedFlow?

[julian]

Why do you need to convert? Based on your SO post, since you already have a Flow and a MutableSharedFlow, why not just collect the Flow, and set the collected values on the MutableSharedFlow as you collect them?

I did that, but it doesn't work

I've updated my question in SO post

@Mohamed Ibrahim This succeeds and does what you want, I think:

val ps = PublishSubject.create<Int>()
val mf = MutableSharedFlow<Int>()
val pf = ps.asFlow()
    .onEach {
        mf.emit(it)
    }
launch {
    pf.take(3).collect()
}
launch {
    mf.take(3).collect {
        println("$it") // Prints 1 2 3
    }
}
launch {
    yield() // Without this we suspend indefinitely
    ps.onNext(1)
    ps.onNext(2)
    ps.onNext(3)
}
