quic_lib Examples

This directory contains minimal example applications demonstrating how to use the quic_lib package.

Examples

• echo_client.dart — Demonstrates creating a [QuicEndpoint], connecting to a server, opening a bidirectional stream, and preparing a STREAM frame for sending.
• echo_server.dart — Demonstrates binding a [QuicEndpoint] to a local address, polling active connections, and registering each connection in its own isolate.

Running the examples

Echo server

dart run echo_server.dart

The server will listen on 127.0.0.1:4433. Press Ctrl+C to stop it gracefully.

Echo client

In a separate terminal, run:

dart run echo_client.dart

The client will bind to an ephemeral port, connect to 127.0.0.1:4433, open a bidirectional stream, and prepare a packet containing a simple "Hello, QUIC!" message.

Note

These examples are scaffolding that demonstrate the public API surface. Some end-to-end wire paths (such as fully completing a handshake over UDP) may still be under active development. See the package README and doc/ folder for the full architecture and roadmap.
