# isBefore method

bool isBefore(

1. DateTime other

)

Whether this DateTime occurs before `other`.

The comparison is independent of whether the time is in UTC or in the local time zone.

    final now = DateTime.now();
    final earlier = now.subtract(const Duration(seconds: 5));
    print(earlier.isBefore(now)); // true
    print(!now.isBefore(now)); // true

    // This relation stays the same, even when changing timezones.
    print(earlier.isBefore(now.toUtc())); // true
    print(earlier.toUtc().isBefore(now)); // true

    print(!now.toUtc().isBefore(now)); // true
    print(!now.isBefore(now.toUtc())); // true

## Implementation

    external bool isBefore(DateTime other);
