Localization

GetX Translations with keys in Strings, and one map file per language. Current locale is stored in shared preferences.

How it works

GetMaterialApp uses:

locale: MySharedPref.getCurrentLocal(),
translations: LocalizationService.getInstance(),

Service shape:

class LocalizationService extends Translations {
  static Locale defaultLanguage = supportedLanguages['en']!;

  static Map<String, Locale> supportedLanguages = {
    'en': const Locale('en', 'US'),
    'ar': const Locale('ar', 'AR'),
  };

  static Map<String, TextStyle> supportedLanguagesFontsFamilies = {
    'en': const TextStyle(fontFamily: 'Poppins'),
    'ar': const TextStyle(fontFamily: 'Cairo'),
  };

  @override
  Map<String, Map<String, String>> get keys => {
    'en_US': enUs,
    'ar_AR': arAR,
  };
}

Keys:

class Strings {
  static const String hello = 'hello';
}

Per-language maps (every Strings.* key must appear in every map):

const Map<String, String> enUs = {
  Strings.hello: 'Hello!',
};

final Map<String, String> arAR = {
  Strings.hello: 'مرحباً!',
};

In widgets:

Text(Strings.hello.tr)

Switch language:

LocalizationService.updateLanguage('en'); // or 'ar'

updateLanguage checks supportedLanguages, writes shared pref, then Get.updateLocale.

Read locale:

LocalizationService.getCurrentLocal();
// or
MySharedPref.getCurrentLocal();

If shared pref has no value, it returns LocalizationService.defaultLanguage.

Change default language

Set:

static Locale defaultLanguage = supportedLanguages['en']!;

to the supported code the user wants ('ar', 'fr', …). That code must already exist in supportedLanguages. If it does not, add the language first.

Done when defaultLanguage points at the requested supported locale.

Change language (runtime)

Call LocalizationService.updateLanguage('{code}') with a key from supportedLanguages (en, ar, …). If the code is not supported, add the language first, then switch.
