How do I handle errors in Dart's async programming?

In Dart, you can handle errors in async programming using try-catch blocks or by using the catchError method on Futures.

Can you give me an example of using try-catch with async functions?

Sure! Here's a simple example:

Future<void> fetchData() async {
  try {
    var data = await getDataFromApi();
    print(data);
  } catch (e) {
    print('Error: $e');
  }
}

What about using catchError? How does that work?

Using catchError, you can handle errors directly on the Future like this:

getDataFromApi()
  .then((data) => print(data))
  .catchError((e) => print('Error: $e'));

Are there any best practices for error handling in Dart?

Yes, it's best to handle specific exceptions, log errors for debugging, and provide user-friendly messages.
