Is there an operator to go from List<Flow<A>> to Flow<List<A>>?
I’m currently applying the following:

.flatMapLatest { items: List<Flow<A>> ->
  combineTransform(items) {
    emit(it.toList())
  }
}

but am wondering if this is common enough and/or is handled in a better way with a different operator.

Maybe just combine(items) { it.toList() } ? I don’t know any simpler method

Beware: if your list is empty there is no emission!

We wrote a lint check that forbids the combine iterable function and have a custom flow that emits an empty list

This one did hit us pretty badly.
