First App

Step 1

Create or use an existing flutter app project and add flutter_webrtc to your pubspec.yaml file

flutter create myapp

• Add flutter_webrtc to your pubspec.yaml file

flutter pub add flutter_webrtc

Step 2

Setup required permissions for audio and video, link to Project Settings

Using navigator.mediaDevices.getUserMedia to get access to the camera and microphone.

you can view getUserMedia docs here

class _MyHomePageState extends State<MyHomePage> {  RTCVideoRenderer? _renderer;  MediaStream? _stream;
  void _openCamera() async {    // create and initialize renderer    _renderer ??= RTCVideoRenderer();    await _renderer!.initialize();
    //     try {      _stream = await navigator.mediaDevices          .getUserMedia({'audio': false, 'video': true});    } catch (e) {      //if you get an error, please check the permissions in the project settings.      print(e.toString());    }
    // set the MediaStream to the video renderer    _renderer!.srcObject = _stream;    setState(() {});  }

Step 3

render the video renderer in the widget tree

  @override  Widget build(BuildContext context) {    return Scaffold(      appBar: AppBar(        backgroundColor: Theme.of(context).colorScheme.inversePrimary,        title: Text(widget.title),      ),      body: Center(        child: SizedBox(          width: 320,          height: 240,          // render the video renderer in the widget tree          child: _renderer != null ? RTCVideoView(_renderer!) : Container(),        ),      ),      floatingActionButton: FloatingActionButton(        onPressed: _setup,        tooltip: 'open camera',        child: const Icon(Icons.camera_alt),      ),    );  }
