How do you handle CPU-bound tasks without freezing the Flutter UI?
Tests whether you know async/await yields for I/O but cannot parallelize CPU work. A strong answer defines Isolates as isolated heaps with message-passing, contrasts them with threads, and shows how compute() wraps Isolate.spawn.
Tests whether you understand that Dart's single-threaded event loop with async/await only yields on I/O, leaving CPU work blocking the UI. A strong answer distinguishes cooperative multitasking from true parallelism; defines an Isolate as a separate memory heap with its own event loop and message ports; contrasts Isolates with OS threads since they share no mutable state; and explains that compute() wraps Isolate.spawn, handling message serialization and Future-based results.
