Mobile chat app built with Flutter

The Flutter Chat Messaging SDK includes a low-level SDK, core controllers, and customizable UI components, providing you with the exact amount of control you need. Create your desired Flutter messaging experience, complete with rich messages, reactions, threads, media uploads, localization, and complete offline support.

The best place to start is the Flutter Chat App Tutorial. The tutorial teaches you how to use our UI components and to customize the SDK to best fit your brand and user experience needs. See our ever-growing list of examples and tutorials, demoing how to extend our SDK to add peer-to-peer payments, animated reactions and stickers, interactive games, and much more.
