Greetings, I've been looking at this reactive programming package and really liked the idea of bringing a similar implementation of RxJS / RxJava, I was wondering how I can contribute to this, documentation, adding new operators or something that can help grow this library.

Sure, any of these contributions are welcome. Also better tests, and finding and fixing bugs.

The code is working, but not in many regards not very complete. I think there is also space for various extension packages, i.e. to support different schedulers based on platform (HTML, Flutter).

IMHO, the current API is awkward, but I have started to use Static Extension Methods which will hopefully solve that problem with the upcoming version of Dart (Branch: extension-methods).

Update 2 years later: The API has stabilized and with static extension methods it has become significantly better. Feature and test coverage is great. What is still missing are extension packages for particular platforms like HTML and Flutter.

We are currently porting a complex typescript client to dart. The rx library has served us quite well, but now we are running into race condition issues when running the integration tests in Flutter (regardless of the actual mobile platform).

Can you please elaborate what are these missing extension packages for Flutter? We may contribute with it.

I suspect when using this library in Flutter you need custom schedulers to run code in the right zones (threads), similar to how RxJava does in Android, and RxJs does in HTML. I have never used this library in Flutter or HTML, so it might at least require some documentation of how to make it work.

Note that there is also rxdart which seems to be much more widely used in Flutter, however it builds on top of the Dart Streams so the semantics might be different.

Our initial attempt was using rxdart, but eventually we had to switch due to the fact you've mentioned.

I will do some investigation, but I would be surprised if CurrentZoneScheduler, which is built on Zones, would require any change. AFAIK Zones should behave equally regardless of platform.

Update: It turns out the race condition was a bug in our code and rx seems to run just fine in Flutter (android and ios)
