Hi,

I am triying to create an app with the capabilities of turning on/off the flashlight and zooming.  
I see 2 different ways:

1- Implementing the applyConstraints() (which has the torch and zoom advanced options) and getCapabilities() in MediaStreamTrack.js  
2- Or maybe using the RN camera (from which I should be able to control the torch and zoom) along with webrtc, maybe following this [Live stream not working while using react-native-camera along with webRTC](https://react-native-webrtc.discourse.group/t/live-stream-not-working-while-using-react-native-camera-along-with-webrtc/259)

Any trace or indication in how to perform or start with this would be highly appreciated.

Thank you

I made a naive implementation of this some time ago.

See last commits in the fork I did

>
> The WebRTC module for React Native. Contribute to lino202/react-native-webrtc development by creating an account on GitHub.

and a minimalist example for seeing the module working

I am so sorry but for now is not something I was thinking of doing. Feel free to collaborate if you want!
