Chatter – Building a Flutter Chat Application From Scratch

Chatter is a demo application showing how to create a chat app from scratch using Flutter and the Stream Chat Flutter Core package.

Where To Start

If you’re new to Stream Chat Flutter, we recommend taking a look at the official tutorial: https://getstream.io/chat/flutter/tutorial/

Using the Stream Chat Flutter package you’ll get a full working chat experience with minimal code.

This repository demonstrates how to use the Stream Chat Flutter Core package to build your own UI components from scratch.

The video tutorials provide a step-by-step guide to understand the code in this repository: Chatter YouTube series playlist
