flutter-handling-concurrency — Skills

What it does

Core Concepts

Decision Matrix: Async vs. Isolates

Implementing Standard Asynchronous UI

Offloading Short-Lived Heavy Computation

Establishing Long-Lived Worker Isolates

Main Isolate: The default thread where UI rendering and event handling occur. Blocking this isolate causes UI freezing (jank).

Worker Isolate: A spawned isolate used to offload CPU-bound tasks (e.g., decoding large JSON blobs) to prevent Main Isolate blockage.

Offload CPU-intensive tasks to background isolates while keeping Flutter UIs responsive.
