Has anyone already written a multiplatform, flow-based sharedpreferences/userdefaults?

[gildor]

not flow based, but there are a couple of implementations for example by @russhwolf

Flow may be used as replacement for listeners, make sense to contribute imo

That’s great, thank you Andrey

I'm working on it and already using dev version of it:

The module's root: https://github.com/LouisCAD/Splitties/tree/develop/modules/preferences

The (not documented yet) Flow related code is here: https://github.com/LouisCAD/Splitties/blob/eb4cc37027b0f6a9ca34be24816016142ae8d869/modules/preferences/src/commonMain/kotlin/splitties/preferences/PrefDelegate.kt#L34-L60
What I did was to port Android's SharedPreferences interface on macOS and iOS, then translate the delegate API I was using on Android previously.

I plan to support observing changes made on the underlying NSUserDefaults instead of only the instance of the wrapper for iOS and macOS, but I'm struggling a little with the KVO Obj-C APIs.
