Hi there, recently I had need for some kind of a MutableLiveData, but easily integratable with Flows and without the Android dependency. I came up with this solution, but I wonder, if there is a simpler solution. Any ideas?

You can use

chan.value

to get the most recent value. Conflated channel sends always succeed, therefore you can use

offer

instead of

send

So

var value
    get() = chan.value
    set(value) { chan.offer(value) }

Just invoke

chan.offer(initialValue)

in an init block

It seems like you could just use a typealias to ConflatedBroadcastChannel.

You’re right, much easier this way, thanks 🙂
