flutter3d_net_webrtc

A flutter3d_net NetTransport over a real WebRTC data channel, part of flutter3d. It is net-02's primary transport. Traffic goes peer to peer, and the relay carries only the SDP/ICE handshake, not every game frame.

It is a separate package instead of a file in flutter3d_net because flutter_webrtc is a plugin with native code for each platform. flutter3d_net is flat Dart and testable under plain dart test, and it is built so that it never has to carry a dependency like that.

import 'package:flutter3d_net/flutter3d_net.dart';
import 'package:flutter3d_net_webrtc/flutter3d_net_webrtc.dart';

// Whoever created the room offers; the one who joined answers — both take
// the signalling transport (net-02's relay) that carries the handshake.
final transport = await WebRtcTransport.createOffer(signallingTransport);
final session = NetSession(transport: transport, /* captureLocalFrame, ... */);
