id_gen is a robust Flutter/Dart package providing a variety of standardized ID generation strategies, including globally unique, readable, time-dependent, transitive, incremental, and decremental IDs. Designed for reliability and security, it supports multiple platforms such as Android, iOS, Web, macOS, Windows, and Linux. The package is well-tested and suitable for applications requiring predictable or secure identifiers across distributed systems. Its modular design allows developers to choose the appropriate ID type based on use case needs.
Use cases
- Generating unique identifiers in distributed systems
