What is the purpose of async and await in Flutter?

Async and await are used in Flutter to handle asynchronous operations, making code easier to read and maintain.

Can you give me an example of how to use async and await in a Flutter app?

Sure! Here's a simple example:

Future<void> fetchData() async {
  var response = await http.get('https://api.example.com/data');
  // Process the response
}

What happens if I don't use await with async functions?

If you don't use await, the function will return a Future immediately, and the code following it will execute without waiting for the async operation to complete.

Are there any performance implications of using async and await?

Using async and await can improve performance by allowing other code to run while waiting for a task to complete, but it can also introduce complexity if not managed properly.
