Overview
The uuid package provides a comprehensive implementation of RFC4122 UUID standards (v1, v4, v5, v6, v7, v8) for Dart, enabling secure and reliable generation and parsing of universally unique identifiers. It supports all major platforms including Android, iOS, Web, macOS, Windows, and Linux. The package is ideal for applications requiring unique identifiers for data records, session management, or distributed systems. With clean, intuitive APIs, it simplifies integration into Flutter and Dart projects.
Use cases
- Generating unique IDs for database records
- Creating session tokens
- Identifying entities in distributed systems
- Ensuring data integrity across services
- Supporting offline-first app state management
Key features
- Supports multiple UUID versions (v1, v4, v5, v6, v7, v8)
- Cross-platform compatibility
- Robust parsing and validation
- Simple, fluent API
- RFC4122 compliant
Suitable for
- Backend services using Dart
- Flutter apps needing unique identifiers
- Data synchronization across devices
- Security-sensitive applications
- Applications requiring standardized ID formats
Considerations
- Ensure proper UUID version selection based on use case
- Be mindful of privacy implications with v1 UUIDs
- Verify UUID format when parsing user input
- Avoid generating high volumes of v1 UUIDs in performance-critical paths
- Check for updates due to ongoing RFC standard evolution
