What is use case of coroutines flow ? What does it provide ?

Flow<T>

should be used when a class exposes multiple values of

so any use case where you would register a listener for multiple emissions,

Flow<T>

should be used

if it’s a single asynchronous value, then

suspend () -> T

is the proper type

Any example for multiple emissions ? In respect to Android would be much better 😅

On Android it may be every callback-based API, you can convert onClickListener events to flow and any other View event, BroadcastReceiver.onReceive and many other

The same as RxJava and similar to LiveData

A Flow is reactive and it will, when active, emit objects/data over time. Like Andrey said, Flow is similar to a cold observable in Rx (Java).
