Hi, beginner flow user here, please what operator do I need to conditionally run a flow

flow2

based on the condition of an upstream flow

flow1

? this is what I have tried but I am not sure if I actually should be doing the tagged line

flow1()
 .flatMapLatest { res ->
   if(res.conditionIsFalse) {
     flowOf() // works but wondering if there is an operator that doesn't require this
   } else {
     flow2()
   }
 }
 .onEach { flow2Res -> 
   // do something with flow2Res
 }
 .launchIn(scope)

flatMapLatest

is pretty much what you want, you can use

emptyFlow()

to not emit anything.

thanks @wasyl, looks like what I am doing works then.

Be aware of the difference between

flatMapMerge

,

flatMapConcat

and `flatMapLatest`: the first one will run multiple inner flows simultaneously and emit their values as they come,

concat

version will also run inner flows but maintain order in which they were triggered (so concat their emissions), and

latest

one will cancel the previous inner flow once the new item is handled

makes sense @wasyl, thanks a lot. I am just understanding what the

flatMapMerge

doc means for the first time with your explanation 😅
