V4 Migration Guide

Warning

Flutter > = v3.16.x uses material 3 by default which breaks the UI of some of the components. If you want to use these versions, you need to set the useMaterial3 parameter to false in the ThemeData.

eg.

MaterialApp(
  theme: ThemeData(
    useMaterial3: false,
  ),
  ...
);

StreamChat widget overrides the useMaterial3 parameter to false by default so if you are using StreamChat widget, you don't need to set it manually.

For upgrading from V6 to V7, please refer to the V4 Migration Guide

Packages

We provide a variety of packages depending on the level of customization you want to achieve.

`stream_chat`

A pure Dart package that can be used on any Dart project. It provides a low-level client to access the Stream Chat service.

`stream_chat_persistence`

This package provides a persistence client for fetching and saving chat data locally. Stream Chat Persistence uses Moor as a disk cache.

`stream_chat_flutter_core`

This package provides business logic to fetch common things required for integrating Stream Chat into your application. The core package allows more customisation and hence provides business logic but no UI components.

`stream_chat_flutter`

This library includes both a low-level chat SDK and a set of reusable and customizable UI components.

`stream_chat_localizations`

This library includes a set of localization files for the Flutter UI components.
