Alternative for Tags in flutter

Question

This is the older version of an application. I used Tags widget in that app. But now Tags doesn't support null safety and outdated. Can you please suggest me alternative and write same functional code using alternate packages.

import 'package:flutter_tags/flutter_tags.dart';


List<Items> _newArrivalsItems = [];
  List<Items> _selectedNewArrivalsItems = [];
  List<String> _selectedNewArrivalsItemCodes = [];


Widget _buildFilter() {
    List<String> added = [];

    return Container(
      child: Tags(
        runSpacing: 5,
        spacing: 5,
        itemCount: _newArrivalsItems.length,
        itemBuilder: (index) {
          final obj = _newArrivalsItems[index];
          if (added.contains(obj.iGRPCODE)) {
            return Container();
          }
          added.add(obj.iGRPCODE);
          return ItemTags(
            index: index,
            title: obj.iGRPDESC,

            active: true,
            removeButton: ItemTagsRemoveButton(
              onRemoved: () {
                // Remove the item from the data source.
                setState(() {
                  // required
                  _selectedNewArrivalsItemCodes.remove(obj.iGRPCODE);
                  setState(() {});
                });
                //required
                return true;
              },
            ), // OR null,
            onPressed: (item) {
              final value = _selectedNewArrivalsItemCodes.remove(obj.iGRPCODE);
              if (!value) _selectedNewArrivalsItemCodes.add(obj.iGRPCODE);
              setState(() {});
            },
            onLongPressed: (item) => print(item),
          );
        },
      ),
    );
  }

I found 'flutter_tags_x' as alternative and it is working fine. Thanks for the responses
