Check if one date is between two dates or not

Question

I have the following three dates

Date1 = 2022-02-07 20:06:14.379392
Date2 = 2021-02-07 20:06:14.379393
Date3 = 2022-02-06 00:00:00.000

and I want to check, if Date3 is between Date1 and Date2.

As of right now the Date3 is between Date1 and Date2, but how can I check this?

Currently I am trying something like this

if (Date1.isBefore(Date3) &&
    Date2.isAfter(Date3)) {
  print("date3 is between date1 and date2");
} else {
  print("date3 isn't between date1 and date2");
}

But it's always showing, that the Date3 is not between Date1 and Date2.

If you parse the dates as DateTime then fix the condition, it should work. Side note: you should rename your variables to something more explicit, ex. dateMin/dateMax, dateLowerBound/dateUpperBound, etc.

void main() {
    final date1 = DateTime.parse('2022-02-07 20:06:14.379392');
    final date2 = DateTime.parse('2021-02-07 20:06:14.379393');
    final date3 = DateTime.parse('2022-02-06 00:00:00.000');

    if (date3.isBefore(date1) && date3.isAfter(date2)) {
        print("date3 is between date1 and date2"); // <- this is printed.
    }
    else {
        print("date3 isn't between date1 and date2");
    }
}
