Overview
The compute package brings Flutter's compute function to non-Flutter Dart applications, enabling efficient execution of CPU-intensive tasks on a separate isolate. This allows Dart programs on Android, iOS, Web, macOS, Windows, and Linux to offload heavy computations without blocking the main thread. It’s particularly useful for math-heavy operations, data processing, or any task that benefits from parallel execution. The package maintains compatibility with Flutter’s original compute API while being independent of Flutter’s framework.
Use cases
- Running CPU-intensive calculations
- Processing large datasets
- Performing background math operations
- Improving app responsiveness
- Executing long-running tasks safely
- Enabling isolate-based concurrency
Key features
- Cross-platform support
- Matches Flutter's compute API
- Simple function interface
- No Flutter dependency
- Thread-safe execution
- Lightweight and standalone
Suitable for
- Dart CLI tools
- Server-side Dart apps
- Web applications
- Desktop and mobile apps
- Performance-critical code
- Non-Flutter Dart projects
Considerations
- Requires isolate awareness
- Limited to CPU-bound tasks
- Not suitable for I/O operations
- Must handle serialization of arguments
- Isolate lifecycle management
- Potential memory overhead for frequent calls
