Is there sth concatWith for Flow?

[Paul Woitaschek]

Like this

kotlin
fun <T> Flow<T>.concatWith(other: Flow<T>): Flow<T> {
  return flow {
    collect { emit(it) }
    other.collect { emit(it) }
  }
}

well, if you put the two flows into another flow, you can flattenConcat

but I think the general idea is to not add too many operators to the core API, and leave them as separate libraries that can be included

This is interesting I was looking for a merge function that takes a vararg of Flow<T> and outputs a new Flow<T>
I guess I will have to write my own.

Yeah it's actually pretty smile, it's just a flow forEach launch collect emit loop
