I am new to kotlin flows and trying to add Flows to one of my project and facing an issue while converting list of objects of one type to another as shown below. Basically, am not sure which operator to be used for this.

//Repository - method return type is  Flow<List<HistoryEvent>>
fun getHistoryEvents(): Flow<List<HistoryEvent>>

//ViewModel - calling repository method and trying to convert data to List<AccessoryEvent>

val accessoryEvents : LiveData<List<AccessoryEvent>>=  liveData{
                                                      repository.getHistoryEvents()

                                                  // what operator to be used to convert from List<HistoryEvent> to List<AccessoryEvent>

                                                        .collect()
                                                      }

I tried like below

val eventHistory: LiveData<List<AccessoryEventType>> = 
        liveData {
            deviceRepository.getDeviceEventHistoryFor("abcd")
                .map { historyEvents ->
                    emit((historyEvents.map { AccessoryEventType.getEventType(it) }))
                }
                .collect()
        }

after this, all elements in the returned list are same and equals to the last emitted element. Am not sure what I am doing wrong

don’t know anything about android but why are you

emit

in your map ?

to convert

Flow<xx>

to

Livedata<xx>

also

Flow<List<HistoryEvent>>

seems like a smell

ok..basically how to convert List of objects of one type to another. In my case, I have to convert

List<HistoryEvents>

to

List<AccessoryEventType>

should be a very simple then:

List<HE>.map { convertHEtoAET(it) }

ok. lemme see how to convert to

Livedata<xx>

after doing

map

without

emit
