Coroutine

Kotlin coroutine flow includes cold flow and hot flow. SharedFlow and StateFlow are two of the hot flows. They can broadcast values ​​to several receivers, so can be used to implement the publisher-subscriber pattern.

Flow is one of the features of Kotlin Coroutines. It allows a suspending function to return multiple values.

Kotlin’s coroutines are used to replace threads. They do not block threads, and they can be cancelled. Coroutine core helps you manage the number of threads.
