ULID class abstract interface

Universally Unique Lexicographically Sortable Identifier.

ULID Specification

Implemented types

• Comparable<ULID>

Constructors

ULID.fromBytes(Uint8List data)

Generate a ULID from given bytes. data must be 16 bytes in length.

factory

ULID.fromString(String string)

Create ULID object from given (valid) ULID string.

factory

ULID.nextMonotonicULID(ULID previous, [int? timestamp])

Generate the next monotonic ULID. If an overflow happened while incrementing the random part of the given previous ULID value then the returned value will have a zero random part.

factory

ULID.nextULID([int? timestamp])

Generate a ULID.
