getLocaleDirection method

Future<String> getLocaleDirection(String locale)

Implementation

Future<String> getLocaleDirection(String locale) async {
  final state = await _stateStore.load(
    config: config,
    projectRootPath: projectRootPath,
  );

  // Check if this is a custom locale with configured direction
  if (state.customLocaleDirections.containsKey(locale)) {
    return state.customLocaleDirections[locale]!;
  }

  // Check if it's a predefined RTL language
  final languageCode = getLanguageCode(locale);
  const rtlLanguages = {
    'ar', // Arabic
    'fa', // Farsi/Persian
    'he', // Hebrew
    'ku', // Kurdish
    'ps', // Pashto
    'sd', // Sindhi
    'ur', // Urdu
    'yi', // Yiddish
  };

  if (rtlLanguages.contains(languageCode)) {
    return 'rtl';
  }

  return 'ltr'; // Default to LTR
