    I will say on the topic of multiplatform, rxjava isn't directly supported. However there is a multiplatform Rx library called reaktive which has way better testing support compared to coroutines at the moment. although if multiplatform is something you're interested in doing I would start the project off rather than do it later to save time in the long run. If you're interested, the mpp Todo sample is a good example demonstrating a lot of everything.
