Squadron is a multithreading library for Dart and Flutter applications, providing cross-platform workers and worker pools to offload CPU-bound and long running tasks.

Squadron takes care of the plumbing aspects to make your code run in platform threads, while keeping it callable from your app's main thread seamlessly.

Developers simply focus on implementing the services that need to run in Squadron Workers.

Squadron comes with annotations leveraged by companion package squadron_builder to automatically generate boilerplate code. This code is necessary to initialize and wrap custom services into workers and worker pools. It can be written manually, but using squadron_builder instead is highly recommended.

Typical use-cases:

fight UI jank: execute code that creates UI jank in a single Worker -- it will help keep your app responsive to user actions!
parallelize computations: distribute workloads to a Worker or to a WorkerPool -- this will help get results quicker!
