compareTo method
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(BookingValues other) {
final otherStart = other.start.totalRangeTime;
if (start.totalRangeTime == otherStart) {
return 0;
} else if (start.totalRangeTime < otherStart) {
return -1;
} else {
return 1;
}
}
