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
