Error Handling

An extension method for handling the result of a Future with success and error callbacks.

The result method allows you to provide two callbacks: one for handling the success case when the Future completes successfully, and one for handling the error case when an exception occurs.

Example usage:

Future<int> fetchNumber() async {
  // Simulating an asynchronous operation
  await Future.delayed(Duration(seconds: 2));

  // Simulating an error
  throw Failure('Failed to fetch number');
}

void handleSuccess(int number) {
  print('Fetched number: $number');
}

void handleError(Failure error) {
  print('Error occurred: ${error.message}');
}

void main() {
  fetchNumber().result(handleError, handleSuccess);

  // or

  final request = fetchNumber();

  request.result<Failure, int>(
  (e) => print('Error occurred: ${e.message}');  // could replace `e` with error
  (s) => print('Fetched number: $s');            // could replace `s` with number
  );
}
