get all week Mon-Sun fron Datetime-CodePudding

How can I get all days of the week of a Datetime? example: DateTime.utc(2022, 12, 21). The result should be: mon(19)-tue(20)-wed(21)-thu(22)-fri(23)-sat(24)-sun(25)

CodePudding user response：

To get all weekdays for a given DateTime, you can use:

void main() {
  print(getAllWeekDays(DateTime.now()));
}

List<DateTime> getAllWeekDays(DateTime datetime) {
  return List.generate(7, (index) {
    return datetime.subtract(Duration(days: datetime.weekday - index));
  });
}

Prints:

[2022-12-18 11:46:53.333, 2022-12-19 11:46:53.333, 2022-12-20 11:46:53.333, 2022-12-21 11:46:53.333, 2022-12-22 11:46:53.333, 2022-12-23 11:46:53.333, 2022-12-24 11:46:53.333]

Note: this isn't a complete answer to get exactly what you want, as you'll need to format the DateTimes. But to do so, you can use the intl package. Additionally, take a look at: How do I format a date with Dart?
