isBefore method Null safety
- DateTime other
Returns true if this 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);
