isAfter 方法
- DateTime other
如果 this 发生在 other
之后,则返回 true。
比较与时是否在 UTC 或本地时区无关。
final now = DateTime.now();
final later = now.add(const Duration(seconds: 5));
print(later.isAfter(now)); // true
print(!now.isBefore(now)); // true
// This relation stays the same, even when changing timezones.
print(later.isAfter(now.toUtc())); // true
print(later.toUtc().isAfter(now)); // true
print(!now.toUtc().isAfter(now)); // true
print(!now.isAfter(now.toUtc())); // true
实现
external bool isAfter(DateTime other);
