Permission denied on android

[alr2413]

i tried the following simple code on a real android 10 device, but it throws permission denied:

ElevatedButton(
            onPressed: () async {
              httpClient = CurlClient();
              var request = http.Request('get', 'http://google.com');
              var response = await httpClient.send(request);
              print(response.statusCode);
              httpClient.close();
            },
            child: Text('Test'),
          ),

E/flutter ( 3833): [ERROR:flutter/lib/ui/ui_dart_state.cc(186)] Unhandled Exception: ProcessException: Permission denied

You may need to enable network permissions: https://flutter.dev/docs/development/data-and-backend/networking#android

i already did that.

Oh... you are using the curl-based client. Why do you need to use that in a Flutter app?

[alr2413]

to create a socks proxy app. is that possible? Do i need to add a curl repo to my android build.gradle file?

[isoos]

to create a socks proxy app. is that possible?

This curl client was developed for a specific server app that requested HTTP via curl infrequently. I don't think it would be great to execute curl on each request, and it wouldn't be a proxy.

Maybe this package would help you? https://pub.dev/packages/socks5

Ok. Thanks.
