Localization & Translation

DashLearn features resilient multi-language support built using GetX Translations. The project structure uses Mixins and Part files to keep the translation logic clean and modular.

Supported Languages

The app currently supports 10 languages out of the box:

• English (en_US)
• Bangla (bn_BD)
• Arabic (ar_SA)
• German (de_DE)
• Spanish (es_ES)
• French (fr_FR)
• Hindi (hi_IN)
• Italian (it_IT)
• Portuguese (pt_BR)
• Turkish (tr_TR)

Directory Structure

Translations are located in lib/app/translations/.

• app_translations.dart: The main entry point that aggregates all languages.
• _en.dart, _es.dart, etc.: Individual language files defined as parts.

Adding a New Language

To add a new language (e.g., Japanese ja_JP), follow these steps:

1. Create the Language File

Create a new file lib/app/translations/_ja.dart. Define a mixin that implements your translations:

lib/app/translations/_ja.dart

part of 'app_translations.dart';

mixin JaKeys on Translations {
  final jaKeys = <String, String>{
    'language': '言語',
    'details': '詳細',
    // ... add all required keys
  };
}

2. Register in app_translations.dart

Open lib/app/translations/app_translations.dart and register your new mixin.

1. Add Part Directive:

   part '_tr.dart';
   part '_ja.dart'; // Add this

2. Add Mixin:

   class AppTranslations extends Translations
       with EnKeys, ..., TrKeys, JaKeys { // Add JaKeys

3. Add to Keys Map:

   @override
   Map<String, Map<String, String>> get keys => {
     'en_US': enKeys,
     'ja_JP': jaKeys, // Register specific locale
   };

Changing the Default Locale

To change the app’s default language (fallback), update your GetMaterialApp configuration in main.dart or app_pages.dart (wherever initialized):

GetMaterialApp(
  // ...
  locale: Locale('ja', 'JP'),
  fallbackLocale: Locale('en', 'US'),
);
