  @override

    return ReorderableColumn(
      header: Text('List-like view but supports IntrinsicWidth'),
      children: sectionList
          .map((e) => ListTile(
                title: Text(e.name ?? ''),
                key: ValueKey(e.objectId),
              ))
          .toList(),

        // _pantryStore.sectionReorder(oldIndex, newIndex);
      },
    );
  }
