When I use Dio to download a file, dio_cache_interceptor throws an error: Unhandled Exception: Unsupported operation: Response type not supported : ResponseType.stream. #155

How should dio_cache_interceptor be configured to ignore the ResponseType.stream type? I haven't found the corresponding configuration. I am using the dio.download method to download files.

dio download code:

response = await dio.download(urlPath, savePath,
        options: Options(responseType: ResponseType.stream, extra: {
          "extraIgnoreCacheKey": true,
        }), onReceiveProgress: (int count, int total) {
      print("$count $total");
    }, cancelToken: requestToken);

Yes ResponseType.stream is not supported.

You can make exceptions like this (pseudo code):

options: cacheOptions.copyWith(policy: CachePolicy.noCache).toOptions()
