Translations

Translations are kept as a simple key-value dictionary map. To add custom translations, create a class and extend Translations.

import 'package:get/get.dart';

class Messages extends Translations {
  @override
  Map<String, Map<String, String>> get keys => {
        'en_US': {
          'hello': 'Hello World',
        },
        'de_DE': {
          'hello': 'Hallo Welt',
        }
      };
}

Using translations

Just append .tr to the specified key and it will be translated, using the current value of Get.locale and Get.fallbackLocale.

Text('title'.tr);

Locales

Pass parameters to GetMaterialApp to define the locale and translations.

return GetMaterialApp(
    translations: Messages(), // your translations
    locale: Locale('en_US'), // translations will be displayed in that locale
    fallbackLocale: Locale('en_US'), // specify the fallback locale in case an invalid locale is selected.  
    supportedLocales: <Locale>[Locale('en_US'), Locale('de_DE')] // specify the supported locales
);

Change locale

Call Get.updateLocale(locale) to update the locale. Translations then automatically use the new locale.

var locale = Locale('en_US');
Get.updateLocale(locale);

System locale

To read the system locale, you could use Platform.localeName.

return GetMaterialApp(
    locale: Locale(Platform.localeName),
);
