What is it?

Twake Chat is a decentralized chat app built on the Matrix protocol, developed by Linagora. It lets users talk over the open Matrix network, and it works with other Matrix clients such as Element, Nheko and NeoChat. The app covers messaging, group and public chats, spaces, and end-to-end encryption with emoji verification and cross signing.

The codebase is written in Dart with Flutter, so one code base targets Android, iOS, Linux and web. The web target uses flutter_vodozemac for end-to-end encryption and is packaged as a Docker image served by nginx, with runtime configuration supplied through a config.json file. The project is a fork of FluffyChat and uses the Matrix Dart SDK.

The repository also documents the development setup for each platform, asset generation with flutter_gen, translation through Weblate, and a profiling workflow for Flutter Web using Chrome DevTools.
