Does anybody knows some ObservableList implementation on Kotlin (or java :disappointed:)?

JavaFX has a pretty comprehensive system of observables (including ObservableList), but I'm not sure how well they work outside the JavaFX world.

I need something on Android, ideally without additional dependencies

The `List&lt;&gt;` interface isn’t too huge, you could just wrap a normal list and add callbacks yourself. Especially by using interface delegation, you only need to override the methods that mutate the original list.

yeah i rolled my own, though i swear just the other day I swear I saw something that was an ObservableList but now I forget where or what it was

I found few, android.databinding, tornadofx and javafx all have implementations. But I'd like to avoid big dependencies for single class

yeh i don't think you'll want tornadofx or javafx dependencies in Android (unless i'm mistaken about ways those can be used).

Note that the TornadoFX one is the JavaFX one (TornadoFX is at it's core a Kotlin wrapper around JavaFX)
