Parsing an invalid ISO date string or out-of-range calendar date in Luxon throws an Error or rolls over to a valid date.

Автор образца записал здесь то, чего ожидал бы разработчик или модель. Контракт ниже — это то, что действительно выполнялось.

DateTime.fromISO with an unparsable string or impossible calendar date does not throw and does not roll over, returning an invalid DateTime object with isValid false and toISO null
Operations and arithmetic on an invalid DateTime propagate isValid false without throwing, returning NaN for toMillis and null for toISODate
DateTime.fromObject with month 0 is treated as out of range and invalid rather than wrapping to January or December
Setting Settings.throwOnInvalid to true switches Luxon from silent invalid object propagation to immediately throwing an Error on invalid parsing, units, or timezones
Interval.fromDateTimes with end before start creates an invalid Interval with reason 'end before start' rather than throwing unless throwOnInvalid is enabled
