screen sharing for desktop. (#135)
* screen sharing for desktop (WIP). * use git repo for testing. * update. * Add sourceId/frameRate to ScreenShareCaptureOptions. * Compatible with flutter web. * Rendering of camera and screenshare video tracks at same time. * Remote screen sharing is shown first, and fixed sub/unsub button for screenshare widget. * resolved conflict. * modify flutter-webrtc to pub version. * remove unused import. * chore: Common params for Camera and ScreenShare.
