Hello, I’m trying to use StateFlow to handle a kind of Event, but facing issues when trying to set the same value again (for example when the user clicks the same button again, triggering same event).
Found this GitHub issue: https://github.com/Kotlin/kotlinx.coroutines/issues/2011
With @elizarov comment:

We'll provide a different, more flexible primitive, for those rare cases when you don't want equality-based conflation. Stay tuned.

Do we have anything in the latest release to handle this scenario?

SharedFlow is what you need

Amazing! Thanks @bezrukov
Do you predict any issue in setting up with:

MutableSharedFlow<Event>(1, onBufferOverflow = BufferOverflow.DROP_OLDEST)

Basically I want to use the tryEmit in non suspend functions.

if you will send more than you can process some events will be lost, so I suggest adding some buffer:

MutableSharedFlow<Event>(1, extraBufferCapacity = ... , onBufferOverflow = BufferOverflow.DROP_OLDEST)

[bezrukov]

you're also can set replay = 0 (first param), because most likely you are not interested about event that happened before subscription

Oh I see, thanks!
