Choosing The Right Flutter Package

Why the SDK is split into different packages#

Different applications need different levels of customization and integration with the Stream Chat SDK. To do this, the Flutter SDK is split into three different packages which build upon the last and give varying levels of control to the developer. The higher level packages offer better compatibility out of the box while the lower level SDKs offer fine grained control. There is also a separate package for persistence which allows you persist data locally which works with all packages.

How do I choose?#

The case for stream_chat_flutter#

For the quickest way to integrate Stream Chat with your app, the UI SDK (stream_chat_flutter) is the way to go. stream_chat_flutter contains prebuilt components that manage most operations like data fetching, pagination, sending a message, and more. This ensures you have a nearly out-of-the-box experience adding chat to your applications. It is also possible to use this in conjunction with lower level operations of the SDK to get the best of both worlds.

note

The package allows customization of components to a large extent making it easy to tweak the theme to match your app colors and such. If you require any additional feature or customization, feel free to request this through our support channels.

Summary:

For the quickest and easiest way to add Chat to your app with prebuilt UI components, use stream_chat_flutter

The case for stream_chat_flutter_core#

If your application involves UI that does not fit in with the stream_chat_flutter components, stream_chat_flutter_core strips away the UI associated with the components and provides the data fetching and manipulation capabilities while supplying builders for UI. This allows you to implement your own UI and themes completely independently while not worrying about writing functions for data and pagination.

Summary:

For implementing your own custom UI while not having to worry about lower level API calls, use stream_chat_flutter_core.

The case for stream_chat#

The stream_chat package is the Low-level Client (LLC) of Stream Chat in Flutter. This package wraps the underlying functionality of Stream Chat and allows the most customization in terms of UI, data, and architecture.

Summary:

For the most control over the SDK and dealing with low level calls to the API, use stream_chat.
