unique_id_dart 1.0.0

Generate unique IDs in Dart using Snowflake or UUID v4.

unique_id_dart

English | 中文

Generate unique IDs in Dart using two strategies:

• Short numeric IDs based on Snowflake.
• Standard UUID v4 strings.

Getting started

Add the dependency:

dependencies:
  unique_id_dart: ^1.0.0

Then run:

dart pub get

Usage

import 'package:unique_id_dart/unique_id_dart.dart';

void main() {
  final shortId = uniqueId();
  final longId = uniqueId(shorter: false);

  print(shortId);
  print(longId);
}

API

• uniqueId({bool shorter = true})
  • true (default): Snowflake-based numeric ID.
  • false: UUID v4 string.

Notes

• Snowflake uses a fixed workerId and datacenterId internally. If you need multi-node uniqueness guarantees, consider exposing configuration or forking.
• Run tests with dart test. See example/ for a runnable demo.
