Dart Language Async

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.
