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.

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:

More languages will be added in the future. Feel free to contribute to add more languages.

Add dependency

Add this to your package's pubspec.yaml file, use the latest version Pub

 stream_chat_localizations: ^latest_version

Then run flutter packages get


import 'package:flutter/material.dart';
import 'package:stream_chat_localizations/stream_chat_localizations.dart';

void main() {

class MyApp extends StatelessWidget {
  Widget build(BuildContext context) {
    return MaterialApp(
      // Add all the supported locales
      supportedLocales: const [
      // 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 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 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.
