DateTime(2020).until(DateTime(2021));
// all full hours of 2020/01/01
DateTime(2020, 1, 1).until(DateTime(2020, 1, 2), by: 1.hours);
Implementation
Iterable<DateTime> until(DateTime to,
{Duration by = const Duration(days: 1)}) sync* {
for (var date in rangeTo(to, by: by).withoutLast()) {
yield date;
}
