monthDelta method Null safety
Determines the number of months between two DateTime objects.
For example:
DateTime date1 = DateTime(year: 2019, month: 6, day: 15);
DateTime date2 = DateTime(year: 2020, month: 1, day: 15);
int delta = monthDelta(date1, date2);
The value for delta
would be 7
.
Implementation
static int monthDelta(DateTime startDate, DateTime endDate) {
return (endDate.year - startDate.year) * 12 + endDate.month - startDate.month;
}
