Hey all I know flutter and golang but not the dark mysteries of webrtc. Happy to collaborate to make it come together. What repo do you want it in ?

@gedw99 I suggest we keep the example as simple as possible. Unless flutter has some specific needs, I think the example can live in the main repo for now. Feel free to ask for help if anything is blocking you. You may also want to join the #pion channel of the gophers slack since we're really active on there.

ok. I will work on a PR.

I created an example of flutter for sfu-ws here sfu-ws/flutter, I did some simple tests, Publisher is works, but Subscriber in iOS can only hear the sound, the webrtc log shows that the decoder could not find the keyframe.

Reasons and test steps:
1, Run sfu-ws
2. Start publishing using the web client.
     pc.createOffer provides VP8/playload=96 => sfu
     pc.setRemoteDescription(answer) <= sfu

3, Start to subscribe to use the Flutter client
      pc.createOffer provides H264/payload=96 => sfu (The real payload of VP8 is 100 on iOS.)
      pc.setRemoteDescription(answer) <= sfu
     
The Flutter client starts to receive the video stream, but the playoad does not match, the webrtc framework will get the rtp from SFU's VP8/pt=96, and the error as H264/pt=96 will not be decoded.

If the Subscriber process is createOffer by sfu, and the client answer, maybe can fixed this issue.

Any joy in integrating flutter with pions?

Hey @dtel

All the work is done! I just need to merge the PR :( we are working on release v2.0.0, right when that is done we should be able to do this easily.

This is done!

sfu-ws is a many-to-many conferencing demo. In the flutter we have an example applications that works just like the index.html
