5 years ago Try to write a small a small program using dart:io and get that to work. If you can't get the following to work then there is a problem with how your HTTP proxy is configured, how you are supplying credentials, or how dart:io handles %40 in it's encoding, or how your proxy handles %40 in it's code (not unlikely)..
import 'dart:io';
import 'dart:convert';
Future<void> main() async {
final client = HttpClient();
final uri = Uri.parse('https://pub.dartlang.org/api/packages/test');
final req = await client.getUrl(uri);
final res = await req.close();
final raw = await res.toList().then((l) => l.expand((i) => i).toList());
final out = json.fuse(utf8).decode(raw) as Map<String, dynamic>;
final ver = out['latest']['version'];
print('Latest version of test package is $ver');
client.close();
}I'm not sure encoding with %40 will work (I have no idea).. you'll likely have to debug dart:io for this to work.
I'm not sure how much we can help you debug specific cases like this, as it could be so many things... From the stack trace it looks as though your proxy might complain about missing authentication...

Hello, I'm sorry to open a new issue if this is actually a dup, but I've not found any solution to my issue for weeks reading all the possibly related issues already submitted, and I feel there's nothing exactly like mine.
I'm using flutter and I encountered a problem when I'm trying to get packages (
flutter packages get),flutter upgrade, and anything that has something to do with fetching packages if I'm behind a corporate proxy that needs authentication. I still can't fetch the packages even if I've set the environment variables as such :http_proxy=http://user%40name:password@hostname:porthttps_proxy=http://user%40name:password@hostname:port(n.b. %40 since my username have '@' character)FYI, I can access pub.dartlang.org just fine in the browser, I could also access every link that was suggested in another related issues like mine.
This is my log from flutter run --verbose :
My
flutter doctorresult is this :Is the only way I could work on this is by using this solution below? https://stackoverflow.com/questions/16808883/dart-pub-fail-behind-a-proxy-is-there-a-way-to-install-the-packages-manually It's pretty bothersome if I need to remote my computer at home everytime I'm updating my dependencies, especially when I still have another dependency issues.
Thank you before, please tell me if you need more information on this.
