Getting Started

Instructions

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

Pubspec

dependencies:
  uuid: ^4.3.2

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'
