I think I found a way:
```
// data is arrow:ChunkedArray
auto list = std::static_pointer_cast<arrow::ListArray>(data->chunk(0));
auto values = list->values();
auto startOffset = list->value_offset(rowIndex);
auto length = list->value_offset(idx + 1) - startOffset;
auto currentSerie = values->Slice(startOffset, length);
```
