How to display Map in dropdown flutter?-CodePudding

I need to implement a dropdown list in which you do not need to select items, but only view it. As an alternative, I decided to use the dropdown widget since I don't know any other options. I ran into a problem, I have a Map with data that needs to be displayed in a drop-down menu, how to do it correctly because it doesn’t work for me, I need to display both weeks and time (attached a screenshot below)? If you know of a better option than using dropdown for my purpose, I'd love to hear a suggestion.

code

class StatusDropdown extends StatefulWidget {
  const StatusDropdown({Key? key}) : super(key: key);

  @override
  State<StatusDropdown> createState() => _StatusDropdown();
}

class _StatusDropdown extends State<StatusDropdown> {
  String? selectedValue;
  bool isChecked = false;

  final Map<String, dynamic> items = {
    'sun': '9:00-14:00',
    'mon': '9:00-14:00',
    'tus': '9:00-14:00',
    'wed': 'Closed',
    'thu': '00:00-24:00',
    'fri': '9:00-14:00',
    'sat': '9:00-14:00',
  };

  @override
  Widget build(BuildContext context) {
    return Container(
      width: 141,
      height: 28,
      child: DropdownButtonHideUnderline(
        child: DropdownButton2(
          offset: const Offset(0, -12),
          items: ...,
        ),
      ),
    );
  }
}

It needs to be done
