## Flutter Chat Tutorial
|
|
|
|
The best place to start is the [Flutter Chat Tutorial](https://getstream.io/chat/flutter/tutorial/).
|
|
It teaches you how to use this SDK and also shows how to make common changes.
|
|
|
|
## Example App
|
|
|
|
This repo includes a fully functional example app with setup instructions.
|
|
The example is available under the [example](https://github.com/GetStream/stream-chat-flutter/tree/master/example) folder.
|
|
|
|
## Add dependency
|
|
|
|
```yaml
|
|
dependencies:
|
|
stream_chat_flutter: ^0.1.11
|
|
```
|
|
|
|
You should then run `flutter packages get`
|
|
|
|
### Android
|
|
|
|
All set ✅
|
|
|
|
### iOS
|
|
|
|
The library uses [flutter file picker plugin](https://github.com/miguelpruivo/flutter_file_picker) to pick
|
|
files from the os.
|
|
Follow [this wiki](https://github.com/miguelpruivo/flutter_file_picker/wiki/Setup#ios) to fulfill iOS requirements.
|
|
|
|
We also use [video_player](https://pub.dev/packages/video_player) to reproduce videos. Follow [this guide](https://pub.dev/packages/video_player#installation) to fulfill the requirements.
|
|
|
|
To pick images from the camera we use the [image_picker](https://pub.dev/packages/image_picker) plugin.
|
|
Follow [these instructions](https://pub.dev/packages/image_picker#ios) to check the requirements.

### Business logic components
|
|
|
|
We provide 2 Widgets dedicated to business logic and state management:
|
|
|
|
- [StreamChat](https://pub.dev/documentation/stream_chat_flutter/latest/stream_chat_flutter/StreamChat-class.html)
|
|
- [StreamChannel](https://pub.dev/documentation/stream_chat_flutter/latest/stream_chat_flutter/StreamChannel-class.html)
|
|
|
|
### 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.
|
|
|
|
- [ChannelHeader](https://pub.dev/documentation/stream_chat_flutter/latest/stream_chat_flutter/ChannelHeader-class.html)
|
|
- [ChannelImage](https://pub.dev/documentation/stream_chat_flutter/latest/stream_chat_flutter/ChannelImage-class.html)

|
|

|

|
|
### Customizing styles
|
|
|
|
The Flutter SDK comes with a fully designed set of widgets which 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 own default styling, there are two ways to change the styling:
|
|
|
|
1. Initialize the `StreamChatTheme` from your existing `MaterialApp` style
|
|
```dart
|
|
class MyApp extends StatelessWidget {
|
|
final Client client;
|
|
|
|
MyApp(this.client);
|
|
|
|
@override
|
|
Widget build(BuildContext context) {
|
|
final theme = ThemeData(
|
|
primarySwatch: Colors.green,
|
|
);
|
|
|
|
return MaterialApp(
|
|
theme: theme,
|
|
home: Container(
|
|
child: StreamChat(
|
|
streamChatThemeData: StreamChatThemeData.fromTheme(theme),
|
|
client: client,
|
|
child: ChannelListPage(),
|
|
),
|
|
),
|
|
);
|
|
}
|
|
}
|
|
```
|
|
|
|
2. Construct a custom theme and provide all the customizations needed
|
|
```dart
|
|
class MyApp extends StatelessWidget {
|
|
final Client client;
|
|
|
|
MyApp(this.client);
|
|
|
|
@override
|
|
Widget build(BuildContext context) {
|
|
final theme = ThemeData(
|
|
primarySwatch: Colors.green,
|
|
);
|
|
|
|
return MaterialApp(
|
|
theme: theme,
|
|
home: Container(
|
|
child: StreamChat(
|
|
streamChatThemeData: StreamChatThemeData.fromTheme(theme).copyWith(
|
|
ownMessageTheme: MessageTheme(
|
|
messageBackgroundColor: Colors.black,
|
|
messageText: TextStyle(
|
|
color: Colors.white,
|
|
),
|
|
avatarTheme: AvatarTheme(
|
|
borderRadius: BorderRadius.circular(8),
|
|
),
|
|
),
|
|
),
|
|
client: client,
|
|
child: ChannelListPage(),
|
|
),
|
|
),
|
|
);
|
|
}
|
|
}
|
|
```
