What is Dart's async programming model?

Can you explain Dart's async programming model?

Sure! Dart's async programming model allows you to write asynchronous code using the async and await keywords, making it easier to handle operations like I/O without blocking the main thread.

How do I use the Future class in Dart?

The Future class represents a potential value or error that will be available at some time in the future. You can create a Future using the Future() constructor or by using async functions.

What is the difference between Future and Stream in Dart?

A Future is used for a single asynchronous result, while a Stream is used for a sequence of asynchronous events. You can listen to a Stream to receive multiple values over time.

Can you give me an example of using async and await?

Certainly! Here's a simple example:

Future<void> fetchData() async {
  var data = await getDataFromServer();
  print(data);
}
