janus_client 
It is a feature rich flutter package, which offers all webrtc operations supported by Janus: the general purpose WebRTC server, it easily integrates into your flutter application and allows you to build webrtc features and functionality with clean and maintainable code.
Note
What it will do?
- It will help you in establishing communication with Janus server using either REST or Websocket depending on what you prefer
- It will provide you meaningful APIs for individual plugins so you can express your app logic without worrying about internals
What it will not do?
It will not manage every aspect of WebRTC for you by that we mean we only provide core functionalities and features when it comes to WebRTC, since this library uses flutter_webrtc for managing all of webrtc stack so you will need to refer its documentation when there's some use cases which we do not cover or does not exist in examples. This is done intentionally by design to give developers complete flexibility while also making sure library is lightweight and does not become a bloatware.
A classic example of that would be changing output device on a native device for example you want to switch from speaker to headsets or bluetooth audio device you will need to use flutter_webrtc's Helper utility class:-
Helper.selectAudioOutput(deviceIdOfBluetoothDevice)

Deprecated Api v1(0.0.x)
If by any chance you are looking for (although you shouldn't) old api then you can switch to v1 branch, as it is very unstable and hard to maintain it was deprecated and will not recieve any fixes or feature updates. It is highly recommended you migrate your code to latest version that is 2.X.X (stable)

Wait there's more... The Javascript Client!
If you loved the api style and architecture of flutter_janus_client and you wishing to have something similar for your next javascript project involving webrtc features.
then worry not because we have got you covered. we have written wrapper on top of our good old janus.js, you might ask why? well the answer to that question is it does not support
type bindings hence no rich ide support, so we proudly presents typed_janus_js(feature rich promisified and reactive wrapper on top of janus.js)
or you can straight away use it by installing from npm npm i typed_janus_js.
