Simple peer-to-peer with WebRTC for Dart. PeerJS port for Flutter.

PeerDart: Simple peer-to-peer with WebRTC #

PeerDart provides a complete, configurable, and easy-to-use peer-to-peer API built on top of WebRTC, supporting both data channels and media streams.

PeerDart mirrors the design of peerjs. Find the documentation here..

Status #

  • Alpha: Under heavy development
  • Public Alpha: Ready for testing. But go easy on us, there will be bugs and missing functionality.
  • Public Beta: Stable. No breaking changes expected in this version but possible bugs.
  • Public: Production-ready

Live Example #

Here's an example application that uses both media and data connections: Example

Setup #

Create a Peer

final Peer peer = Peer("pick-an-id");
// You can pick your own id or omit the id if you want to get a random one from the server.

Data connections #

Connect

const conn = peer.connect("another-peers-id");
conn.on("open", null, (ev,_) => {
	conn.send("hi!");
});

Receive

peer.on("connection", null, (ev, _) => {
	conn.on("data", null, (event, _) => {
		// Will print 'hi!'
		console.log(event.eventData);
	});
	conn.on("open", null, () => {
		conn.send("hello!");
	});
});

Media calls #

Call

final mediaStream = await navigator.mediaDevices
        .getUserMedia({"video": true, "audio": false});

    final conn = peer.call("peerId", mediaStream);

    conn.on("stream", null, (ev, _) {
        _localRenderer.srcObject = ev.eventData as MediaConnection
        // Do some stuff with stream
});

Answer

peer.on("call", null, (ev, context) async {
    final call = ev.eventData as MediaConnection;
    final mediaStream = await navigator.mediaDevices
        .getUserMedia({"video": true, "audio": false});

    call.answer(mediaStream);

    call.on("stream", null, (ev, _) async {
    _localRenderer.srcObject = mediaStream;
    _remoteRenderer.srcObject = ev.eventData as MediaStream

    // Do some stuff.
    });
});

Support #

Works both on mobile and web browsers (Chrome tested.).
