SafeIntId constructor
Create new SafeIntId
generator.
Implementation
SafeIntId({
this.firstYear = 2023,
Random? random,
int randomValues = 1024,
}) {
_firstYearMillis = DateTime.utc(firstYear).millisecondsSinceEpoch;
this.random = random ?? Random();
this.randomValues = max(randomValues, 1);
safeYears =
pow(2, 53) ~/ (this.randomValues * 1000 * 60 * 60 * 24 * 365.2425);
lastSafeYear = firstYear + safeYears - 1;
}
