SharedFlow and MutableSharedFlow were added to coroutines with version 1.4.0. A SharedFlow is a hot flow (one that can exist outside of any subscribers) that can be consumed by multiple subscribers.

The holder of a SharedFlow can use Flow-like constructs to observe the flow (e.g., collect()).

The typical way to set up a SharedFlow is to use a MutableSharedFlow. You can call emit() on the MutableSharedFlow to send a value to all current subscribers.

Here, we set up a MutableSharedFlow that will emit 10 random numbers. And, we set up two subscribers to that flow. Both subscribers will collect the same set of random values, since they are both observing the same flow.
