What is the purpose of the event loop in asynchronous programming?

The event loop in asynchronous programming is responsible for handling and distributing events and tasks that occur outside the main execution thread.

In Flutter (and Dart), the event loop allows:

• Processing asynchronous operations (such as input/output, timers, network requests) without blocking the main UI thread.
• Queuing tasks and executing them as they become ready, ensuring application responsiveness.

Example: when you call an asynchronous function, it places a task in the event queue, and the event loop monitors its execution and invokes the corresponding callbacks when the result is ready.

This enables writing non-blocking code and improves the performance and responsiveness of applications.
