Having this:

fun getAllBusStops(): Flow<List<BusStopEntity>>

and this extension function to transform the BusStopEntity in a BusStop class:

fun BusStopEntity.asBusStop() = BusStop(id = id,name = name,lat = lat,lon = lon)

How can I convert the Flow<List<BusStopEntity>> in a Flow<List<BusStop>> using that extension function?

you can use the kotlin map operator, something like:

fun getAllBusStops(): Flow<List<BusStop>> {
    return getAllBusStops()
        .map { entityList ->
            entityList.map { it.asBusStop() }
        }
}

two map encapsulated? is that correct?

maybe there is a simpler way to achieving what I need? i just need to do this: my database returns a flow of entities, and I need my repo to return that flow of entities transformed in a flow of normal classes
