raven_chat

Livqeno Chat for Flutter — real-time messaging with durable history, presence, typing indicators, reactions, read receipts and threads. Connect, send and listen without writing WebSocket code.

Part of Livqeno, managed real-time communication infrastructure.

Requirements

Dart SDK >= 3.6.0
Flutter >= 3.27.0

Install

dependencies:
  raven_chat: ^0.1.0

Use

The chat token is minted by your backend and is a separate credential from an RTC token — neither works on the other plane.

import 'package:raven_chat/raven_chat.dart';

final chat = RavenChat(token: grant.token, apiUrl: grant.apiUrl);

await chat.connect('room_123');

chat.messages.listen((message) => setState(() => _messages.add(message)));

await chat.send('Hello everyone!');

RavenChat extends ChangeNotifier, so a widget can rebuild from it directly, with typed streams (messages, typing, presence, reactions, readReceipts, connectionStateChanges, errors) for logic outside the widget tree.

Postgres is the source of truth: a message is reported sent only once it is durably stored, a retried send never duplicates, and a client that was offline catches up from history rather than the socket.

Independent of raven_rtc

WebSocket and HTTP only — no WebRTC. A messaging app never pulls in a media stack, and a video app never pulls in a message store. Use both together for a call with a chat panel.
