what's the idiomatic way of accomplish the same rx clickListener + textChangedListener, where the click triggers a save and the changedListener just validates some edittext. (clickListener.withLatestFrom(textChangedListener) ?

Not sure about required semantics, but you always can propose to add operator withLatestFrom with your use case to kotlinx.coroutines issue tracker

ya, i am asking because i didn't find any suitable approach to it. But maybe that's because i'm trying to find an rx replacement. if i think more imperativelly, i can just call a function when a click happens and have the problem solved

[gildor]

no, I just think that such operator doesn’t exist, you can implement it tho

[gildor]

There is alredy PR with it

https://github.com/Kotlin/kotlinx.coroutines/pull/1315

[gildor]

for now you can just copy implementation

[myanmarking]

nice 😮 thanks

[gildor]

still make sense to create a feature request

[octylFractal]

a smaller but perhaps more expensive workaround I thought up:

val clickFlow = ...
val textChangeFlow = ...
val resultFlow = clickFlow.zip(textChangeFlow).distinctUntilChangedBy { it.first }

basically, using the first flow to drive which values are considered part of the flow

[octylFractal]

also requires that the first emits unique values, but for events I think that should suffice
