Stop downstream of LiveData

I'm using Transformations to change the Livedata under certains conditions.



I would like to know if is posible to stop the downstream of starsLD under some condition without stop observing it(i.e. using removeObserver).



I have the following code:



private val sss = StarsFBLiveData()
val starsLD : LiveData<Pair<Int,Long>> = Transformations.map(sss)
tuple ->

gamesLD.value?.let
var i = 0
for(game in it)
if(game.id==tuple.first)
return@map Pair(i,tuple.second)




return@map null
