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").listen((name) {
conn.send("hi!");
})
Receive
peer.on<DataConnection>("connection").listen((connection) {
// On peer closed.
conn.on("close").listen((event) {
setState(() {
connected = false;
});
});
// ....
})
Media calls
Call
final mediaStream = await navigator.mediaDevices
.getUserMedia({"video": true, "audio": false});
final conn = peer.call("peerId", mediaStream);
// Do some stuff with stream
conn.on<MediaStream>("stream").listen((event) {
_remoteRenderer.srcObject = event;
_localRenderer.srcObject = mediaStream;
setState(() {
inCall = true;
});
});
});
Answer
peer.on<MediaConnection>("call").listen((call) async {
final mediaStream = await navigator.mediaDevices
.getUserMedia({"video": true, "audio": false});
call.answer(mediaStream);
// on peer closed
call.on("close").listen((event) {
setState(() {
inCall = false;
});
});
// Get peer stream
call.on<MediaStream>("stream").listen((event) {
_localRenderer.srcObject = mediaStream;
_remoteRenderer.srcObject = event;
setState(() {
inCall = true;
});
});
});
