Hi guys
I was trying to filter upon a sealed class-specific state but the filter function didn't work.
Does anyone know how to do filter against sealed classes state? for example:

sealed class States{
object Loading:States()
data Success(val data: String):States()
}

results.filter{
 it.state is States.Success 
}.forEach{ successState ->
println(successState.data) //Error since this still State not Success State
}

You can use filterIsInstance<States.Success>() instead of a classic filter to have the correct type down the line

Oh, I didn't notice this function. Thanks for your help.
