How to group a list from sqlite db?

[jagadish-pattanaik]

I saw the documentation but I can't get any idea about how to group a list which is from sqlite database.

List<Note2> items2 = new List();
DatabaseHelper db = new DatabaseHelper();

db2.getAllNotes2().then((notes2) {
      setState(() {
        notes2.forEach((note2) {
          items2.add(Note2.fromMap(note2));
        });
      });
    });
  }
ListView( //currently using listview but I want grouped listview
                      shrinkWrap: true,
                      itemCount: items2.length,
                      itemBuilder: (BuildContext context, int position) {
                           .....
                            items2[position].dates //grp according to date
                            ......
