String? operator [](Object? key)

Implementation

String? operator [](Object? key) {
  if (key is String) {
    for (var i = 0; i < arguments.length; i++) {
      String arg = arguments[i];
      if (arg == key) {
        try {
          return arguments[i + 1];
        } catch (e) {
          return null;
        }
      }
    }
  }
  if (key is int) {
    try {
      return arguments[key];
    } catch (e) {
      return null;
    }
  }
  if (key is List<String>) {
    for (final String data in key) {
      final String? args_data = this[data];
      if (args_data != null) {
        return args_data;
      }
    }
  }
  return null;
