Description:

uuid type

UUID type for Dart #

This package provides implementation of Universally Unique Identifier
(UUID) for Dart,
and supports generation, parsing and formatting of UUIDs.
Features:

✅ Creates UUID from string and byte-array, as well as GUID and URN strings
✅ Provides access to variant, version and byte data of UUID
✅ Generates RFC4122 version 1, version 4, or version 5 UUIDs
✅ Implements Comparable for UUID comparison and lexicographical sorting
✅ Runs in web, server, and flutter

RFC Version support:

✅ v1, based on timestamp and MAC address
❌ v2, based on timestamp, MAC address and POSIX UID/GID (DCE 1.1) Not planned
❌ v3, based on MD5 hashing Not planned
✅ v4, based on random numbers
✅ v5, based on SHA-1 hashing
❌ v6, A re-ordering of UUID version 1 so it is sortable as an opaque sequence of bytes
❌ v7, An entirely new time-based UUID bit layout sourced from the widely implemented and well known Unix Epoch timestamp source
❌ v8, A free-form UUID format which has no explicit requirements except maintaining backward compatibility.
