This Flutter Package includes Ant Media Flutter SDK for WebRTC.

To be able to use it, you need to have an Ant Media Server instance first. To be able to get more information, you can check Ant Media Server's website.

If you have Ant Media Server Community Edition, you can only use WebRTC publishing feature.

WebRTC play, Conference and Data Channel features are available in Ant Media Server Enterprise Edition.

Usage

Lets take a look at how to use AntMediaFlutter

AntMediaFlutter.connect

AntMediaFlutter.connect(
        //host
        'wss://<domain>:<port>/<application_name>/websocket',

        //streamID
        'stream1',

        //roomID
        '',

        //token
        '',

        //type
        AntMediaType.Publish,

        //userScreen
        true,

        //onStateChange
        (HelperState state) {
          switch (state) {
            case HelperState.CallStateNew:
              setState(() {
                _inCalling = true;
              });
              break;
            case HelperState.CallStateBye:
              setState(() {
                _localRenderer.srcObject = null;
                _remoteRenderer.srcObject = null;
                _inCalling = false;
                Navigator.pop(context);
              });
              break;
            case HelperState.ConnectionOpen:
              break;
            case HelperState.ConnectionClosed:
              break;
            case HelperState.ConnectionError:
              break;
          }
        },

        //onLocalStream
        ((stream) {
          setState(() {
            _remoteRenderer.srcObject = stream;
          });
        }),

        //onAddRemoteStream
        ((stream) {
          setState(() {
            _remoteRenderer.srcObject = stream;
          });
        }),

        // onDataChannel
        (datachannel) {
          print(datachannel.id);
          print(datachannel.state);
        },

        // onDataChannelMessage
        (channel, message, isReceived) {
          print("Message Received: ${message.received}");
        },

        // onupdateConferencePerson
        (streams) {},

        //onRemoveRemoteStream
        ((stream) {
          setState(() {
            _remoteRenderer.srcObject = null;
          });
        }),

        //ice servers
        [
          {'url': 'stun:stun.l.google.com:19302'},
        ],

        // callbacks
        (command, mapData) {});

Connect is the main function that we ca do pretty much everything with it's parameters. Let's look at it's parts and how we can use it for different purposes like WebRTC Publishing, WebRTC Playing etc.

Sections of the connect function

-> Host

Host is the websocket url of your Ant Media Server instance.

-> Stream ID

Stream ID is used to identify each stream for publshing and playing purposes.

-> Room ID

Room ID is used in the WebRTC Multitrack Conference mode.

-> Type

Type is used to determine different modes. Possible options:

  • AntMediaType.Publish
  • AntMediaType.Play
  • AntMediaType.Peer
  • AntMediaType.Conference
  • AntMediaType.DataChannelOnly

-> User Screen

User Screen is used to switch betwenn screen and camera publishing mode during initialization part.

-> On State Change

On State Change is the status of the websocket connection between Ant Media Server and the device which uses the SDK. Possible options:

  • HelperState.CallStateNew
  • HelperState.CallStateBye
  • HelperState.ConnectionOpen
  • HelperState.ConnectionClosed
  • HelperState.ConnectionError

-> On Local Stream

On Local Stream is triggered whenever we started sending stream to the Ant Media Server.

-> On Add Remote Stream

On Add Remote Stream is triggered whenever we receive a new remote stream from the Ant Media Server.

-> On Data Channel

On Data Channel is triggered when the data channel state changed.

-> On Data Channel Message

On Data Channel Message is triggered whenever we receive a new data channel message.

-> On Update Conference Person

On Update Conference Person is triggered whenever someone added/removed from the conference room on the fly.

-> On Remove Remote Stream

On Remove Remote Stream is triggered whenever you stopped publishing yourself or the stream that you are playing stopped publishing.

-> Ice Servers

Ice Servers is the list where you can define your own turn/stun server list.

-> Callbacks

Callbacks you can listen all the callbacks which are sended from the Ant Media Server side.
