uuid_type 2.1.0

UUID type, parser and generators. Can generate v1, v4, and v5 UUIDs

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.

Requirements

• Dart SDK >= 2.12.0
• crypto package
