How can you cancel an HTTP request made with the Dio library?

In the Dio library for Flutter, you can cancel an HTTP request using the CancelToken object.

Example:

import 'package:dio/dio.dart';

final dio = Dio();
final cancelToken = CancelToken();

// Making a request
void fetchData() async {
  try {
    final response = await dio.get(
      'https://example.com/data',
      cancelToken: cancelToken,
    );
    print(response.data);
  } catch (e) {
    if (CancelToken.isCancel(e)) {
      print('Request canceled');
    } else {
      print('Error: $e');
    }
  }
}

// Cancel the request
void cancelRequest() {
  cancelToken.cancel('User canceled the request');
}

Thus, calling cancelToken.cancel() will abort the request.
