I think this is doable, In my opinion this is how I will go about it, Install camera package along with Livekit package Make a call to Livekits API, during the time of connecting or before initiating the Livekit SDK listen to the connection. Once the connection it's successful,you know what to do next.

@gray-photographer-38040 I'm already using the camera package for exactly this purpose. I was curious if it is possible to use livekit only. Since it also has access to local camera stream

@silly-train-16715 You can create LocalAudio/VideoTrack in preJoin page, use fastConnect to pass them to room. https://github.com/livekit/client-sdk-flutter/blob/main/lib/src/options.dart#L19-L28

Hi @freezing-lifeguard-43174. Thank you for the hint with VideoTrack. It helped. But I didn't get the part with fast connect. Can you provide an example on how to use pass already created local VideoTrack to the room on creation/connection?

No problem, let me create a PR to implement this example

Hi @freezing-lifeguard-43174. I've tested. Thats a shame that I missed the

track

argument in

TrackOption

😅. Thanks. However I noticed a problem: I joined the room with two phones and noticed that even mics on both devices were on and the corresponding icons were showing that the participants have their mics on (even blue outline was flashing), only one participant was hearing the other. I guess you've made this branch after release of version of 1.4.0 for Flutter. Maybe it is something related to this commit https://github.com/livekit/client-sdk-flutter/commit/7b7272156018e50b8be94a53a0a3112eb253c1e7

Are you using Android or iOS? I will try to reproduce the issue you describe

Both

Just tested, it should be normal, the first time after 1.4.0, the app will use the handset by default, so the volume will be low, you can try to switch to the speaker after the first connection.

So I have to manually switch to speaker every time I connect to room?

Do you mean a volume indicator? to verify the microphone you are using

Yes. I want to show user that the mic is on and everything is working before he enters the call

okay, I'll find a way to implement this feature.

Thank you. It'll be great

Any info on this branch going to prod

@worried-leather-93857 Here is a branch where you can view an example on how to implement this feature https://github.com/livekit/client-sdk-flutter/tree/feat/prejoin-example Regarding audio. Currently it is not possible, I believe. But Duan promised to take a look.
