List<String> get spannedItems

returns List of Spanned Cells as

["A1:A2", "A4:G6", "Y4:Y6", ....]

return type if String based cell-id

Implementation

List<String> get spannedItems {
  _spannedItems = FastList<String>();

  for (int i = 0; i < _spanList.length; i++) {
    _Span? spanObj = _spanList[i];
    if (spanObj == null) {
      continue;
    }
    String rC = getSpanCellId(spanObj.columnSpanStart, spanObj.rowSpanStart,
        spanObj.columnSpanEnd, spanObj.rowSpanEnd);
    if (!_spannedItems.contains(rC)) {
      _spannedItems.add(rC);
    }
  }

  return _spannedItems.keys;
