How to Make a Video Conference Tools App with Flutter

Peer-to-Peer Video

class VideoCallScreen extends StatefulWidget {
  final String roomId;
  const VideoCallScreen({super.key, required this.roomId});
  @override State createState() => _VideoCallScreenState();
}

class _VideoCallScreenState extends State {
  final _localRenderer = RTCVideoRenderer();
  final _remoteRenderer = RTCVideoRenderer();
  RTCPeerConnection? _pc;
  MediaStream? _localStream;

  @override
  void initState() {
    super.initState();
    _initRenderers();
    _initCall();
  }

  Future _initRenderers() async {
    await _localRenderer.initialize();
    await _remoteRenderer.initialize();
  }

  Future _initCall() async {
    final mediaConstraints = {
      'audio': true, 'video': {'facingMode': 'user'},
    };
    _localStream = await navigator.mediaDevices.getUserMedia(mediaConstraints);
    _localRenderer.srcObject = _localStream;
  }

  @override
  Widget build(BuildContext context) {
    return Column(
      children: [
        Expanded(child: RTCVideoView(_remoteRenderer, mirror: true)),
        SizedBox(
          height: 160,
          child: RTCVideoView(_localRenderer, mirror: true),
        ),
      ],
    );
  }

  @override
  void dispose() {
    _localRenderer.dispose();
    _remoteRenderer.dispose();
    _localStream?.dispose();
    super.dispose();
  }
}

UI & UX Suggestions

Use a dark background, green call-active indicator, red end-call button colour palette to match the app's purpose. Keep the navigation simple — a bottom nav bar or a single-scroll layout works best for this type of app. Make sure every interaction provides haptic or visual feedback so the app feels responsive and polished.
