DateTime provides millisecondsSinceEpoch and microsecondsSinceEpoch properties. For example:

var unixTimeMilliseconds = DateTime.now().toUtc().millisecondsSinceEpoch;

For whatever reason, there's no secondsSinceEpoch. Since traditional Unix timestamps are in seconds, you might also want this:

extension SecondsSinceEpoch on DateTime {
  int get secondsSinceEpoch => millisecondsSinceEpoch ~/ 1000;
}

Note the ~/ for integer division.

String time = DateTime.now().millisecondsSinceEpoch.toString().substring(0, 10);

Darts DateTime has a property millisecondsSinceEpoch which should be what unix timestamp is as well. 

DateTime.now().toUtc().millisecondsSinceEpoch
