dart-uuid

Version 3.0.0 has breaking API changes

Simple, fast generation of RFC4122 UUIDs.

Features:

• Generate RFC4122 version 1, version 4, or version 5 UUIDs
• Runs in web, server, and flutter
• Cryptographically strong random number generation on all platforms
  • Defaults to non-crypto generator, see UuidUtil for cryptoRNG
• API

Getting Started

Instructions

1. Open a command line and cd to your projects root folder
2. In your pubspec, add an entry for dart-uuid to your dependencies (example below)
3. pub install
4. If you wish to run tests, go into packages/dart-uuid/ and run 'dart test/uuid_test.dart'

Pubspec

pub.dartlang.org: (you can use 'any' instead of a version if you just want the latest always)

dependencies:
  uuid_enhanced: ^3.0.0

import 'package:uuid_enhanced/uuid_enhanced.dart';

Then create some ids ...

// Generate a v1 (time-based) id
Uuid.fromTime(); // -> '6c84fb90-12c4-11e1-840d-7b25c5ee775a'

// Generate a v4 (random) id
Uuid.randomUuid(); // -> '110ec58a-a0f2-4ac4-8393-c866d813b8d1'

// Generate a v4 (crypto-random) id
Uuid.randomUuid(random: UuidUtil.cryptoRNG());
// -> '110ec58a-a0f2-4ac4-8393-c866d813b8d1'

// Generate a v5 (namespace-name-sha1-based) id
Uuid.fromName('www.google.com', namespace: Uuid.NAMESPACE_URL);
// -> 'c74a196f-f19d-5ea9-bffd-a2742432fc9c'

// Generate all 0s UUID
Uuid.empty();
// -> '00000000-0000-0000-0000-000000000000'

Testing

Benchmarking

Its pretty quick, but no official benchmarking.
