How do you handle concurrency in Dart applications?

In Dart, concurrency is managed using asynchronous programming constructs such as Future, Stream, and async/await. These tools allow you to perform non-blocking operations, making your application more responsive by not waiting for long-running tasks to complete.

A candidate should mention the importance of using these constructs to manage tasks like network requests, file I/O, or database operations efficiently. They may also discuss how Dart’s event loop handles these asynchronous tasks.

Look for candidates who can explain the practical applications of these constructs and demonstrate an understanding of when and how to use them effectively. Follow-up questions can explore their experience with specific scenarios or performance tuning in asynchronous contexts.
