Question

I am doing a dart code where I need to find the number of days and nights between two dates, in which the time period for night is specified as night start at 8pm and end at 5am. How to calculate the day time in minutes and night time in minutes if start time is today morning 10am and end time is tomorrow 11 am

Answer 1

Here's a sample code:-

int minutesBetween(DateTime from, DateTime to) {
 from = DateTime(from.year, from.month, from.day);
 to = DateTime(to.year, to.month, to.day);
 return (to.difference(from).inHours / 1440).round(); //dividing by 1440 coz a day consists of 1440 minutes
}
