short of writing my own extension function, is there any more concise way of writing

flow {
    emit(suspendFunction())
}

I know I could use flowOf(…) but the call site is not in a suspend function already

[alexandrepiveteau]

Something like ::suspendFunction.asFlow() ?

[William Reed]

woah didn’t know that existed

[William Reed]

neat

Somewhat related, for suspending functions (or lambdas) that return a Flow I use these convenience functions:

fun <T> suspendAsFlow(flowLambda: suspend () -> Flow<T>) = flowLambda.asFlow()

fun <T> (suspend () -> Flow<T>).asFlow(): Flow<T> = flow {
    val flow = this@asFlow()
    emitAll(flow)
}

the .asFlow is useless if you have external params. I really wish the library provided this. Everybody then calls it differently, mine is simpleFlow { }
