If device locale is not on the supported locales, it does not use fallback it gives an eror.

[arrrrny]

Lets say user has device locale fr-FR which is not in the supported locales.

    runApp(
      EasyLocalization(
        supportedLocales: const [
          Locale('de'),
          Locale('en'),
          Locale('es'),
          Locale('pl'),
          Locale('ru'),
          Locale('tr'),
        ],
        path: 'assets/translations',
        fallbackLocale: const Locale('en', 'US'),
        startLocale: const Locale('fr', 'FR'),
        useFallbackTranslations: true,
        useOnlyLangCode: true,
        useFallbackTranslationsForEmptyResources: true,
        child: const App(),
      ),
    );

expected behaviour is to use en, US

however it throws an error instead.

and here is the code:

abstract class AssetLoader {
  const AssetLoader();
  Future<Map<String, dynamic>?> load(String path, Locale locale);
}

///
/// default used is RootBundleAssetLoader which uses flutter's assetloader
///
class RootBundleAssetLoader extends AssetLoader {
  const RootBundleAssetLoader();

  String getLocalePath(String basePath, Locale locale) {
    return '$basePath/${locale.toStringWithSeparator(separator: "-")}.json';
  }

  @override
  Future<Map<String, dynamic>?> load(String path, Locale locale) async {
    var localePath = getLocalePath(path, locale);
    EasyLocalization.logger.debug('Load asset from $path');
    return json.decode(await rootBundle.loadString(localePath));
  }
}

There is no mechanism in place to check the supported locales first before checking assets folder
