        _scrollBy_1();
        return;
      }
      if ((options_OR_x is Map) && y == null) {
        var options_1 = convertDartToNative_Dictionary(options_OR_x);
        _scrollBy_2(options_1);
        return;
      }
      if (y != null && (options_OR_x is num)) {
        _scrollBy_3(options_OR_x, y);
