Any particular reason why there's no

Flow<T>.firstOrNull(): T?

Or did I miss it ?

Some discussion over there: https://github.com/Kotlin/kotlinx.coroutines/issues/1078#issuecomment-481346907. I guess it has to do with the fact that you can't distinguish an empty flow from a first null item but I'm still wrapping my head around that

You could restrict the type to

<T : Any>
