Working with Translations ๐ŸŒ

This project relies on [flutter_localizations][flutter_localizations_link] and follows the [official internationalization guide for Flutter][internationalization_link].

Adding Strings

  1. To add a new localizable string, open the app_en.arb file at lib/l10n/arb/app_en.arb.
{
    "@@locale": "en",
    "counterAppBarTitle": "Counter",
    "@counterAppBarTitle": {
        "description": "Text shown in the AppBar of the Counter Page"
    }
}
  1. Then add a new key/value and description
{
    "@@locale": "en",
    "counterAppBarTitle": "Counter",
    "@counterAppBarTitle": {
        "description": "Text shown in the AppBar of the Counter Page"
    },
    "helloWorld": "Hello World",
    "@helloWorld": {
        "description": "Hello World Text"
    }
}
  1. Use the new string
import 'package:chat_app/l10n/l10n.dart';

@override
Widget build(BuildContext context) {
  final l10n = context.l10n;
  return Text(l10n.helloWorld);
}
