Try with this code

List preferrableDays = [
    'Tuesday',
    'Thursday',
  ];
  List weekList = [
    {'name': 'Sunday', 'short': 'S'},
    {'name': 'Monday', 'short': 'M'},
    {'name': 'Tuesday', 'short': 'T'},
    {'name': 'Wednesday', 'short': 'W'},
    {'name': 'Thursday', 'short': 'T'},
    {'name': 'Friday', 'short': 'F'},
    {'name': 'Saturday', 'short': 'S'},
  ];
  @override
  Widget build(BuildContext context) {
    return Scaffold(
        body: Center(
      child: Row(
        children: [
          ...weekList.map((e) => Text(
                e['short'],
                style: TextStyle(
                    color: preferrableDays.contains(e['name'])
                        ? Colors.black
                        : Colors.grey),
              ))
        ],
      ),
    ));
  }
