      final response = await dio.get('https://jandan.net/api/post/dot',
          cancelToken: testTask);
      print('Success:$response');
      Future<void>.delayed(const Duration(milliseconds: 30), () {
        print('------cancel------${DateTime.now()}');
        testTask.cancel();
      });

      dio
          .get('https://jandan.net/api/post/dot')
          .then((value) => print(value))
          .catchError((e) {
