parseByteSizeAuto function

ParsedByteSize parseByteSizeAuto(String input, { ByteStandard standard = ByteStandard.si, RoundingMode rounding = RoundingMode.round, double thresholdBytes = 9.22e18, })

Parses input and returns either ByteConverter or BigByteConverter depending on thresholdBytes. Useful when inputs may exceed 64-bit range. Values >= thresholdBytes are parsed and returned as ParsedBig.

Implementation

ParsedByteSize parseByteSizeAuto(
  String input, {
  ByteStandard standard = ByteStandard.si,
  RoundingMode rounding = RoundingMode.round,
  double thresholdBytes = 9.22e18, // ~2^63 for practical split
}) {
  // Use big-aware parsing for accurate detection across all units
  final preview = parseSizeBig(input: input, standard: standard);
  final bytes = preview.valueInBytes.abs();
  if (bytes >= thresholdBytes) {
    // reparse via Big path for better precision then round
    final big = BigByteConverter.parse(
      input,
      standard: standard,
      rounding: rounding,
    );
    return ParsedBig(big);
  }
  return ParsedNormal(ByteConverter(preview.valueInBytes));
}
