isValidDateParts static method

bool isValidDateParts({
  1. int? year,
  2. int? month,
  3. int? day,
  4. int? hour,
  5. int? minute,
  6. int? second,
  7. int? millisecond,
  8. int? microsecond,
})

Validates date and time components.

Returns true if all provided components are within valid ranges:

  • year: 0-9999
  • month: 1-12
  • day: 1 to max days in month (requires month to be set)
  • hour: 0-23
  • minute: 0-59
  • second: 0-59
  • millisecond: 0-999
  • microsecond: 0-999

Components that are null are not validated.
