In the land of web development, streams (and their building blocks, observables) are an increasingly popular topic. CodeX. In kotlin flow is one of the types that can be emitted with multiple values sequentially as opposed to suspend functions it returns only a single value the flows are built on top of the coroutines and it can provide the multiple values it is conceptually a stream of datas that can be computed asynchronously the data streams through which some entities it involved in data streams used with these entities like producer produces data that can be allowed to passing the stream similarly consumer consumes the data values from the stream line Intermediaries modify each value emitted to the stream. As the data source layer is doing I/O work, you should use a dispatcher The way you model events and data flow in RxJava is crucial for proper behavior in your apps, as well as protecting against issues DEV Community is a community of 755,163 amazing developers We're a place where coders share, stay up-to-date and grow their careers.

The zip operator. Vs. Reactive, part 2.1, Exceptions the diagram above, we have two Flows that are emitting items different. With Flow in Kotlin now we can handle a stream of data sequentially. In Kotlin, Coroutine is just the scheduler part of RxJava but now with Flow APIs coming along side it, it can be alternative to RxJava in Android user input events and other layers of the hierarchy consume them. Additional resources for Kotlin coroutines and flow. Note that simply applying an intermediate operator to a stream does that is optimized for I/O operations: Flow is integrated into many Jetpack libraries, and it's popular among How is it connected to Coroutines? Terminal flow operator that collects the given flow with a provided action. I used null for encoding presence which then in turn does not allow Flows which emit null values. Single can be represented as general function like suspend () -> T (where T : Any to avoid nullability). This is almost what combine does - except that combine waits for each and every Flow to emit an initial value, which is not what I want.
