compareTo method

@override int compareTo(DatePeriod other)

Compares this object to another object.

Returns a value like a Comparator when comparing this to other. That is, it returns a negative integer if this is ordered before other, a positive integer if this is ordered after other, and zero if this and other are ordered together.

The other argument must be a value that is comparable to this object.

Implementation

@override
int compareTo(DatePeriod other) {
  final dateResult = startDate.compareTo(other.startDate);
  if (dateResult != 0) {
    return dateResult;
  }
  return duration.compareTo(other.duration);
}
