Dart's async model is built on Futures (promises) and Streams (observables). Dart engineers use async/await syntax to write non-blocking code that remains readable. Mastery includes understanding the event loop, isolates (threads), and avoiding common pitfalls (race conditions, stream leaks). Senior Dart engineers earn 10-15% premium because they build smooth Flutter apps and efficient backends. Learning: 4-6 weeks (conceptual + practical).
Dart's asynchronous programming model is built on Futures (single-value promises) and Streams (multi-value observables). Engineers use async/await keywords to write non-blocking code that remains readable. Under the hood, Dart's event loop schedules callbacks, preventing thread blocking. Example: Fetch data from API (Future) → Parse response → Update UI. Or listen to user input (Stream) → Filter, debounce → Perform action.
