Hi I m enabling processing of events flow based on other 2 condition flows I wonder if there s a more elegant simpler way to write this chain using if else gt emptyFlow feels edgy ```combine conditionFlow1 Flow lt Boolean gt conditionFlow2 Pair flatMapLatest cond1 cond2 gt if cond1 amp amp cond2 eventSourceFlow events else emptyFlow onEach event gt handleEvent event launchIn scope ```

```combine conditionFlow1 Flow lt Boolean gt conditionFlow2 Pair transformLatest cond1 cond2 gt if cond1 amp amp cond2 emitAll eventSourceFlow events onEach event gt handleEvent event launchIn scope ```

Hi! I'm enabling processing of "events flow" based on other 2 condition flows. I wonder if there's a more elegant/simpler way to write this chain (using if/else -> emptyFlow() feels edgy):

combine(
  conditionFlow1, // Flow<Boolean>
  conditionFlow2,
  ::Pair
)
.flatMapLatest { (cond1, cond2) ->
  if (cond1 && cond2) eventSourceFlow.events else emptyFlow()
}
.onEach { event ->
  handleEvent(event)
}
.launchIn(scope)

transformLatest

combine(
  conditionFlow1, // Flow<Boolean>
  conditionFlow2,
  ::Pair
)
.transformLatest { (cond1, cond2) ->
  if (cond1 && cond2) emitAll(eventSourceFlow.events)
}
.onEach { event ->
  handleEvent(event)
}
.launchIn(scope)
