Dart: Future vs Stream

Can you explain the difference between Future and Stream in Dart?

Sure! In Dart, a Future represents a single value that will be available at some point in the future, while a Stream is a sequence of asynchronous events or values over time.

When would I use a Stream instead of a Future?

You would use a Stream when you need to handle multiple values over time, like listening to user input or data from a web socket. A Future is better for a single response.

Can you give me an example of using a Stream?

Absolutely! You can create a Stream using the Stream.periodic constructor to emit values at regular intervals. For example, it can be used to update a UI every second.

What about error handling in Streams?

In Streams, you can handle errors using the onError callback or by listening to the handleError method. This allows you to manage errors gracefully.
