Overview
flutter_guid is a Dart package that emulates C# Guid functionality, enabling developers to generate and manage UUIDs (Universally Unique Identifiers) within Flutter applications. It provides a Guid class for creating new unique identifiers and allows adding Guid-typed variables to custom classes. The package supports all major platforms including Android, iOS, Web, macOS, Windows, and Linux, making it ideal for cross-platform apps requiring consistent identifier generation. It's particularly useful in scenarios involving data synchronization, session tracking, or database key management where uniqueness and reliability are critical.
Use cases
- Generating unique IDs for database records
- Tracking user sessions across devices
- Synchronizing data between clients
- Creating secure tokens
- Managing entity identifiers in state management
Key features
- Cross-platform UUID generation
- C# Guid-like API design
- Support for Guid type in custom classes
- Immutable and serializable Guid objects
- Easy integration via pub.dev
Suitable for
- Apps needing globally unique identifiers
- Backend-integrated Flutter apps
- Data-heavy applications with sync requirements
- Developers familiar with C# Guid patterns
- Projects requiring consistent ID generation across platforms
Considerations
- Requires understanding of UUID standards
- Not suitable for cryptographic key generation
- May add minor overhead for simple use cases
- Limited to identifier generation, not encryption or hashing
