Hi anyone who would know ? I'm trying to do a flow of ints and trying to detect if the sequence is increasing or decreasing based on last 2 numbers...

so doing like

val flow = MutableSharedFlow<Int>()
flow.tryEmit(1)
flow.tryEmit(2)
flow.tryEmit(3)

and was hoping to do something like following, but that doesn't worj

flow
.zip(flow.drop(1)) { x, y -> y - x}
.collect { incOrDec ->
	println(incOrDec)
}

c
