In Dart, a Future represents a potential value or error that will be available at some point in the future—commonly used for asynchronous operations like network requests, file I/O, or delayed computations.

🕒 What is a Future?

  • A Future<T> returns a value of type T after a delay.

  • It allows non-blocking operations, letting the app remain responsive.

You can use:

  • async/await for readable syntax.

  • .then(), .catchError(), and .whenComplete() for chaining.

⚙️ How Flutter Handles Asynchronous Programming

Flutter uses Dart’s built-in async capabilities to manage:

  1. UI updates after background operations.

  2. Fetching data from APIs.

  3. Reading/writing local storage or databases.

🔄 Widgets and Futures

Flutter has widgets like FutureBuilder to build UIs based on async results:

✅ Summary

  • Future is central to async operations in Dart.

  • Flutter handles it using async/await and reactive widgets like FutureBuilder to keep the UI smooth and responsive.
