如何根据自定义日期Dart对列表进行排序

List<DateTime> dates = [
  DateTime(2022, 10, 1),
  DateTime(2022, 9, 15),
  DateTime(2022, 11, 5),
  DateTime(2022, 8, 25),
];

dates.sort((a, b) => a.compareTo(b));

import 'dart:core';

void main() {
  List<DateTime> dates = [
    DateTime(2022, 10, 1),
    DateTime(2022, 9, 15),
    DateTime(2022, 11, 5),
    DateTime(2022, 8, 25),
  ];

  dates.sort((a, b) => a.compareTo(b));

  print(dates);
}
