      final PdfReference reference =
          PdfPageHelper.getHelper(page!).crossTable!.getReference(annotDic);

    if (index < 0) {
      index = _fieldHelper.annotationIndex;
    }
    final PdfArray? annots =
        PdfAnnotationCollectionHelper.getHelper(page!.annotations)
            .rearrange(reference, _tabIndex, index);
