Are there situations in which you, instead of using a suspend function, use a regular function that returns a Flow that emits a single value? Maybe to use some flow operators that make the code a bit cleaner?

[Robert Williams]

It’s bad practice to create APIs based on how you assume they’ll always be used and a flow that emits exactly once is a confusing API

[Robert Williams]

If the consumer decides it’s more convenient to work with flow it’s pretty simple for them to convert:

flow {
emit(suspendingFun())
}

[Sam]

Even simpler, (suspend () -> T).asFlow() is in the coroutines stdlib so you can write

::suspendingFun.asFlow()

My favourite thing about kotlin is that you learn a new extension function everyday 😅
