Windmillcode 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 (planned) media streams.

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

• supports socketio connections
• sends chunks based on maxMessageSize from local and remote session descriptions

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. (media is public alpha)
• Public: Production-ready

Setup

Create a Peer

<!-- for development -->
final Peer peer = Peer(options:PeerOptions(
      // debug: LogLevel.All,
));
<!-- for production -->
final Peer peer = Peer(options:PeerOptions(
      // debug: LogLevel.All,
      clientType: "socketio",
      host: "[YOUR SERVER DOMAIN]",
      port: 9000,
      secure: true));

Data connections

Connect

var peer;
if (peer?.id == null) {
    peer = Peer(options: APPENV.peerdart);
    wait peer!.init();
}

var conn = webrtc.connect(res.data.result["sender_peer_id"]);
conn.on("open",(data) async {
    conn.send("hi!");
})

Receive

if (peer?.id == null) {
    peer = Peer(options: APPENV.peerdart);
    wait peer!.init();
}
peer!.on("connection", (DataConnection? conn) {
    conn?.on("data", (dynamic data) async {
        <!-- work with your data -->
    })
})

Support

Works on android
