Can someone explain the difference between asSharedFlow() on a MutableSharedFlow vs just exposing the MutableSharedFlow as a SharedFlow?

If you expose MutableSharedFlow as SharedFlow then someone could still cast it back to Mutable.. and send values to it. asSharedFlow fully hides the underlying mutable shared flow from consumers

Thanks, so exposing as SharedFlow for something that is 100% internal is not an error, it's just better habit to use the other one to avoid future possible troubles.

Yep both will behave the same, just using asSharedFlow is imo good practice. Even if you don’t develop a library, it’s still good to make it impossible to make a mistake by fellow devs — I can imagine someone doing if (someFlow is MutableSharedFlow) someFlow.castAndSend(x) with good intentions
