Overview
A lightweight, secure, and URL-friendly unique ID generator for Dart, inspired by the popular JavaScript library. It produces cryptographically strong, random strings that are safe for use in URLs, filenames, and database keys. The Dart implementation ensures cross-platform compatibility across Android, iOS, Web, macOS, Windows, and Linux. Designed for simplicity and performance, it avoids predictable patterns while maintaining minimal code size. Ideal for generating short, unique identifiers in applications requiring security and reliability.
