### Changelog
Check out the [changelog on pub.dev](https://pub.dev/packages/stream_chat_localizations/changelog) to see the latest changes in the package.
## What is Localization?
If you deploy your app to users who speak another language, you'll need to internationalize (localize) it. That means you need to write the app in a way that makes it possible to localize values like text and layouts for each language or locale that the app supports. For more information, see the [Flutter documentation](https://flutter.dev/docs/development/accessibility-and-localization/**internationalization**).
What this package allows you to do is to provide localized strings for the Stream chat widgets. For example, depending on the application locale, the Stream Chat widgets will display the appropriate language. The locale will be set automatically, based on system preferences, or you could set it programmatically in your app. The package supports several different languages, with more to be added. The package allows you to override any supported language or add a new language that isn't supported.
## Supported languages
At the moment we support the following languages:
- [English](https://github.com/GetStream/stream-chat-flutter/blob/master/packages/stream_chat_localizations/lib/src/stream_chat_localizations_en.dart)
- [Hindi](https://github.com/GetStream/stream-chat-flutter/blob/master/packages/stream_chat_localizations/lib/src/stream_chat_localizations_hi.dart)
- [Italian](https://github.com/GetStream/stream-chat-flutter/blob/master/packages/stream_chat_localizations/lib/src/stream_chat_localizations_it.dart)
- [French](https://github.com/GetStream/stream-chat-flutter/blob/master/packages/stream_chat_localizations/lib/src/stream_chat_localizations_fr.dart)
- [Spanish](https://github.com/GetStream/stream-chat-flutter/blob/master/packages/stream_chat_localizations/lib/src/stream_chat_localizations_es.dart)
- [Catalan](https://github.com/GetStream/stream-chat-flutter/blob/master/packages/stream_chat_localizations/lib/src/stream_chat_localizations_ca.dart)
- [Japanese](https://github.com/GetStream/stream-chat-flutter/blob/master/packages/stream_chat_localizations/lib/src/stream_chat_localizations_ja.dart)
- [Korean](https://github.com/GetStream/stream-chat-flutter/blob/master/packages/stream_chat_localizations/lib/src/stream_chat_localizations_ko.dart)
- [Portuguese](https://github.com/GetStream/stream-chat-flutter/blob/master/packages/stream_chat_localizations/lib/src/stream_chat_localizations_pt.dart)
- [German](https://github.com/GetStream/stream-chat-flutter/blob/master/packages/stream_chat_localizations/lib/src/stream_chat_localizations_de.dart)
- [Norwegian](https://github.com/GetStream/stream-chat-flutter/blob/master/packages/stream_chat_localizations/lib/src/stream_chat_localizations_no.dart)
More languages will be added in the future. Feel free to [contribute](https://github.com/GetStream/stream-chat-flutter/blob/master/CONTRIBUTING.md) to add more languages.
## Add dependency
Add this to your package's pubspec.yaml file, use the latest version [](https://pub.dartlang.org/packages/stream_chat_localizations)
```yaml
dependencies:
stream_chat_localizations: ^latest_version
```
Then run `flutter packages get`
### Usage
```dart
import 'package:flutter/material.dart';
import 'package:stream_chat_localizations/stream_chat_localizations.dart';
void main() {
WidgetsFlutterBinding.ensureInitialized();
runApp(MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
// Add all the supported locales
supportedLocales: const [
Locale('en'),
Locale('hi'),
Locale('fr'),
Locale('it'),
Locale('es'),
Locale('ca'),
Locale('ja'),
Locale('ko'),
Locale('pt'),
Locale('de'),
Locale('no'),
],
// Add GlobalStreamChatLocalizations.delegates
localizationsDelegates: GlobalStreamChatLocalizations.delegates,
builder: (context, widget) => StreamChat(
client: client,
child: widget,
),
home: StreamChannel(
channel: channel,
child: const ChannelPage(),
),
);
}
}
```
### Adding a new language
To add a new language, create a new class extending `GlobalStreamChatLocalizations` and create a delegate for it, adding it to the `delegates` array.
Check out [this example](https://github.com/GetStream/stream-chat-flutter/blob/master/packages/stream_chat_localizations/example/lib/add_new_lang.dart) to see how to add a new language.
### Override existing languages
To override an existing language, create a new class extending that particular language class and create a delegate for it, adding it to the `delegates` array.
Check out [this example](https://github.com/GetStream/stream-chat-flutter/blob/master/packages/stream_chat_localizations/example/lib/override_lang.dart) to see how to override an existing language.
### ⚠️ Note on **iOS**
For translation to work on **iOS** you need to add supported locales to
`ios/Runner/Info.plist` as described [here](https://flutter.dev/docs/development/accessibility-and-localization/internationalization#localizing-for-ios-updating-the-ios-app-bundle).
Example:
```xml
CFBundleLocalizations
en
hi
fr
it
es
ca
ja
ko
pt
de
no
```
