Hello. I am using the Badoo Reaktive library and the shared module makes an API call and retrieves a list of items. I'd like to expose that list somehow to native android/ios so that they can observe the value when it changes. I was looking into BehaviorSubject<List<xx>> but there's no Interop for that, like there is for Observables, Singles, etc ... and I can't seem to convert the BehaviorSubject to an observable so then to call .wrap() on it.
I'm a bit lost, can anyone point me in the right direction ? How do I expose the list of items i get from the API in an observable fashion so that when the value changes in KMM it also changes in native code ?

Indeed, currently there is not out-of-the-box interop for Subjects. One of the approaches is to expose BehaviorObservableWrapper (since v2.0) plus a method like accept(Something) in your ViewModel or equivalent. Or you can implement a wrapper on your own, similarly to BehaviorObservableWrapper.

i did it this way ... it seems to be working. really hope it's an ok way of doing it 😄

uuu, there's a 2.0 version out. i'm still on 1.2.3

[AndreiBogdan]

seems a wrapper was added in 1.3.0... sheesh !

[AndreiBogdan]

ah, no, sorry. that's a BehaviorObservableWrapper ...

Yes, BehaviorObservableWrapper was added in v2.0. It should work if you don't need to publish events from the iOS side (read only).

Also, it's not clear why you need bookLevelObservable ? It subscribes to bookLevelBehavorSubject and leaks the subscription (the returned Disposable is unmanaged). You could just downcast as val bookLevelObservable: Observable<...> = bookLevelBehaviorSubject.
refresh().subscribe{} also ignores the returned Disposable . Here, you could utilise DisposableScope.
