Android #
The package uses photo_manager
to access the device's photo library.
Follow this wiki to fulfil the Android requirements.
You need to take additional steps if you are targeting Android 13. Read this section for more information.
iOS #
The library uses flutter file picker plugin to pick files from the os. Follow this wiki to fulfill iOS requirements.
We also use video_player

To pick images from the camera, we use the image_picker
plugin.
Follow these instructions to check the requirements.
Web #
For the web, edit your index.html
and add the following in the <body>
tag in order to allow the SDK to override the right-click behaviour:
<body oncontextmenu="return false;">
MacOS #
For MacOS use the file_selector
package.
Follow these instructions to check the requirements.
You also need to add the following entitlement:
<key>com.apple.security.network.client</key>
<true/>
Troubleshooting #
It may happen that you have some problems building the app. If it seems related to the flutter file picker plugin make sure to check this page
Docs #
This package provides UI components required for integrating Stream Chat into your application.
Alternatively, you may use the core package stream_chat_flutter_core
which allows more customisation and provides business logic but no UI components.
If you require the maximum amount of control over the API, please use the low level client package: stream_chat
.
UI Components #
These are the available Widgets that you can use to build your application UI.
Every widget uses the StreamChat
or StreamChannel
widgets to manage the state and communicate with Stream services.
- StreamChannelHeader
- StreamChannelListView
- StreamMessageInput
- StreamMessageListView
- StreamMessageWidget
- StreamChatTheme
- ...
Customizing styles #
The Flutter SDK comes with a fully designed set of widgets that you can customize to fit with your application style and typography.
Changing the theme of Chat widgets works in a very similar way that MaterialApp
and Theme
do.
Out of the box, all chat widgets use their default styling, and there are two ways to change the styling:
- Initialize the
StreamChatTheme
from your existingMaterialApp
style
class MyApp extends StatelessWidget {
final StreamChatClient client;
MyApp(this.client);
@override
Widget build(BuildContext context) {
final theme = ThemeData(
primarySwatch: Colors.green,
);
return MaterialApp(
theme: theme,
builder: (context, child) => StreamChat(
child: child,
client: client,
streamChatThemeData: StreamChatThemeData.fromTheme(theme),
),
home: ChannelListPage(),
);
}
}
- Construct a custom theme and provide all the customizations needed
class MyApp extends StatelessWidget {
final StreamChatClient client;
MyApp(this.client);
@override
Widget build(BuildContext context) {
final theme = ThemeData(
primarySwatch: Colors.green,
);
return MaterialApp(
theme: theme,
builder: (context, child) => StreamChat(
child: child,
client: client,
streamChatThemeData: StreamChatThemeData.fromTheme(theme).copyWith(
ownMessageTheme: MessageTheme(
messageBackgroundColor: Colors.black,
messageText: TextStyle(
color: Colors.white,
),
avatarTheme: AvatarTheme(
borderRadius: BorderRadius.circular(8),
),
),
),
),
home: ChannelListPage(),
);
}
}
Offline storage #
To add data persistence you can extend the class ChatPersistenceClient
and pass an instance to the StreamChatClient
.
class CustomChatPersistentClient extends ChatPersistenceClient {
...
}
final client = StreamChatClient(
apiKey ?? kDefaultStreamApiKey,
logLevel: Level.INFO,
)..chatPersistenceClient = CustomChatPersistentClient();
We provide an official persistent client in the (stream_chat_persistence)[https://pub.dev/packages/stream_chat_persistence] package.
import 'package:stream_chat_persistence/stream_chat_persistence.dart';
final chatPersistentClient = StreamChatPersistenceClient(
logLevel: Level.INFO,
connectionMode: ConnectionMode.regular,
);
final client = StreamChatClient(
apiKey ?? kDefaultStreamApiKey,
logLevel: Level.INFO,
)..chatPersistenceClient = chatPersistentClient;
