Overview
The sqlite3 package provides lightweight and convenient bindings to SQLite using Dart's FFI (Foreign Function Interface), enabling efficient, native-level access to SQLite databases across multiple platforms. It is designed for developers who need a reliable, embedded SQL database solution without the overhead of complex abstractions. The package supports Android, iOS, Web, macOS, Windows, and Linux, making it ideal for cross-platform applications requiring local data persistence with full SQL support.
Use cases
- Offline data storage in mobile apps
- Cross-platform desktop and web applications
- Lightweight database needs in Flutter projects
- Real-time data synchronization with local caching
- Embedding SQL capabilities in serverless functions
Key features
- Native performance via dart:ffi
- Full SQL support including transactions
- Cross-platform compatibility
- Minimal memory footprint
- Easy integration with Flutter
- Supports prepared statements and parameterized queries
Suitable for
- Developers needing fast, low-level SQLite access
- Projects requiring offline-first functionality
- Apps with moderate to high database usage
- Teams preferring minimal dependencies
- Flutter apps targeting multiple platforms
Considerations
- Requires familiarity with SQLite and SQL
- Limited higher-level abstractions compared to ORM libraries
- Manual management of connections and resources
- Not recommended for very large datasets without optimization
- May require additional setup on Web due to JS interop constraints
