Let's have a channel (ConflatedBroadcastChannel) wired in a model.
What is an alternative to SingleLiveData<T>, e.g. something what observe value just once, but on multiple places (observers).

.take(1) would help you?

[Jan Skrasek]

I think not, tak will return just first event and also cancel parent flow -> may cancel channel

[Tristan Caron]

But a ConflatedBroadcastChannel takes 1 arguments, the initial value. It’s always keep the last value pushed into it. You could use .value and get an immediate result.

You need flow.share which is not here yet: https://github.com/Kotlin/kotlinx.coroutines/issues/1261

I don't see how share would help, I want the opossite - observe once.
