Implementation

static Future<Map<String, String>?> loadLanguage(Locale locale) async {
  final Directory baseDirectory = await getApplicationDocumentsDirectory();

  //Overwrite the default loading, if in debug overwrite the local assets

    String jsonAsString =
        await rootBundle.loadString("lang/${locale.languageCode}.json");

    File file =
        await File('${baseDirectory.path}/lang/${locale.languageCode}.json')
            .create(recursive: true); //try catch to add
    file.writeAsString(jsonAsString);
    Map<String, String> convertedJson = _convertStringToJson(jsonAsString);
    return convertedJson;
