StorageNamespace class
Storage alignment utilities providing sector, block, page, and word calculations along with rounding and alignment checks.
Access via the storage namespace:
final size = ByteConverter.fromKiloBytes(512);
print(size.storage.sectors); // Number of sectors
print(size.storage.isWholeSector); // true if aligned to sector boundary
print(size.storage.roundToBlock()); // Round to block boundary
Constructors
- StorageNamespace(double _bytes)
-
Creates a StorageNamespace for the given byte count.

Methods
-
alignmentSlack(
StorageProfile profile, {String? alignment, RoundingMode? rounding}) → ByteConverter - Calculates slack (unused bytes) after alignment.
-
alignTo(
int boundarySize) → ByteConverter - Aligns to a custom boundary size.
-
isAligned(
StorageProfile profile, {String? alignment}) → bool - Returns true when this value satisfies the requested profile alignment.
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-

) → ByteConverter - Rounds up to the next page boundary (4096 B).
-
roundToProfile(
StorageProfile profile, {String? alignment, RoundingMode? rounding}) → ByteConverter - Aligns this value to a StorageProfile bucket.
