I’m working on a Flutter project where I need to compare two DateTime objects, but only by their date. The time component of the DateTime objects is not relevant for my comparison.
Here’s an example of the DateTime objects I’m dealing with:
Dart
DateTime dt1 = DateTime.parse("2023-11-10 11:47:00");
DateTime dt2 = DateTime.parse("2023-11-10 10:09:00");
I want to compare dt1 and dt2 such that only the date (year, month, day) is considered, not the time. How can I achieve this in Flutter? Any help would be appreciated. Thanks!
In Flutter, you can compare two DateTime
objects with respect to only the date (not time) by creating new DateTime
objects from the original ones that contain only the year, month, and day information. Here's an example:
DateTime dt1 = DateTime.parse("2023-11-10 11:47:00");
DateTime dt2 = DateTime.parse("2023-11-10 10:09:00");
// Create new DateTime objects with only year, month, and day
DateTime date1 = DateTime(dt1.year, dt1.month, dt1.day);
DateTime date2 = DateTime(dt2.year, dt2.month, dt2.day);
// Now you can compare date1 and date2
if(date1.compareTo(date2) == 0){
print("Both dates are the same.");
}
if(date1.compareTo(date2) < 0){
print("date1 is before date2");
}
if(date1.compareTo(date2) > 0){
print("date1 is after date2");
}
In this code, date1
and date2
are new DateTime
objects created from dt1
and dt2
respectively, but they only contain the year, month, and day information. The time is set to 00:00:00 by default. Therefore, when you compare date1
and date2
, you're effectively comparing the dates only, not the times.
