Not sure what you are trying to do in the code sample, especially with the DateTime.now()s, but the following example shows how you can easily sort a list of DateTimes:

void main() {
  final dates = [
    DateTime.utc(2001, 2, 2),
    DateTime.utc(2002, 1, 1),
    DateTime.utc(2000, 3, 3),
  ];
  dates.sort();
  print(dates);
}

try this

 List<DateTime> datesList = [];
  datesList.sort(((a, b) => a.compareTo(b)));

with datesList containing all your DateTime
