# compareTo method Null safety

int compareTo (

1. Duration other

)
override

Compares this Duration to `other`, returning zero if the values are equal.

Returns a negative integer if this `Duration` is shorter than `other`, or a positive integer if it is longer.

A negative `Duration` is always considered shorter than a positive one.

It is always the case that `duration1.compareTo(duration2) < 0` iff `(someDate + duration1).compareTo(someDate + duration2) < 0`.

## Implementation

    int compareTo(Duration other) => _duration.compareTo(other._duration);
