Is there a way to use have a

MutableStateFlow<T : Any>

where the initial value is not set immediately? I am migrating from RxJava2

BehaviorSubject<T : Any>

. The value is not initialized until some process finishes. Observers of the value are transient. I would rather it not be a

T?

where I filter out the initial null value. Thanks!

Does SharedFlow replay values for late observers?

yes

Interesting. StateFlow is similar to SharedFlow with replay of 1

yes, and conflated

is similar to SharedFlow

It’s not just similar, it is essentially SharedFlow with replace 1 (though both MutableSharedFlow and MutableStateFlow have some own features, but both based on AbstractSharedFlow implementation) https://github.com/Kotlin/kotlinx.coroutines/blob/master/kotlinx-coroutines-core/common/src/flow/StateFlow.kt#L76-L80

yes that comment just describes exactly what I said, replay 1, conflated, and with an initial value
