collectLatest

Terminal flow operator that collects the given flow with a provided action. The crucial difference from collect is that when the original flow emits a new value then the action block for the previous value is cancelled.

It can be demonstrated by the following example:

flow {
    emit(1)
    delay(50)
    emit(2)
}.collectLatest { value ->
    println("Collecting $value")
    delay(100) // Emulate work
    println("$value collected")
}

prints "Collecting 1, Collecting 2, 2 collected"

Terminal flow operator that collects the given flow with a provided action. The crucial difference from collect is that when the original flow emits a new value then the action block for the previous value is cancelled.

This is a special version of collectLatest for SharedFlow. Its only difference from the usual collectLatest on Flow is that this version returns Nothing to indicate that it never completes. See SharedFlow for more details.
