Saving checkbox value from pre made list to hive

[Redmistt]

Question Hi, i'm trying to make a screen with two listviews, one pre made and one where you add tasks yourself, the pre made list is written in json(doesn't have to be) which works fine but my problem is saving the checkbox state to hive, is there a better way to do this? Let me know if I you need anything else

Code sample

          Visibility(
              visible: categorySelector,
              replacement: ListView.builder(
                  shrinkWrap: true,
                  itemCount: _nbtemplate.length,
                  itemBuilder: (context, index) {
                    return Container(
                      margin: const EdgeInsets.all(4),
                      decoration: BoxDecoration(
                        border: Border.all(
                          width: 2,
                          color: widget.project.isCompleted //||
                              //widget.template.isCompleted
                              ? Colors.green
                              : Colors.grey,
                        ),
                      ),
                      child: ListTile(
                        leading: Checkbox(
