Description: uuid API docs, for the Dart programming language.

# uuid

Version 4.x.x is a complete redesign of the underlying setup, but tries to be API compatible or similar to 3.x.

UuidValue is still Experimental and the API for it is in flux, please pay attention to changelogs and versions.

Simple, fast generation of RFC4122 and RFC9562 UUIDs.

Features:

- Generate RFC4122 version 1, version 4, or version 5 UUIDs
- Supports RFC9562 version 6, version 7, and version 8
- Runs in web, server, and flutter
- Cryptographically strong random number generation on all platforms
- Documentation

## 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

    dependencies:
      uuid: ^4.4.2

    import 'package:uuid/uuid.dart';

    var uuid = Uuid();

Then create some ids ...

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

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

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