Overview
The worker_manager package enables efficient management of CPU-intensive tasks by distributing them across Dart isolates, improving app responsiveness and performance. It simplifies the creation, execution, and coordination of background computations without blocking the main UI thread. Ideal for heavy data processing, image manipulation, or complex calculations, it provides a clean API to handle isolate communication and lifecycle events. The package is cross-platform, supporting Android, iOS, Web, macOS, Windows, and Linux.
