How to setup Proxy in GraphQL

[Adarsh2692]

In the issue https://github.com/zino-hofmann/graphql-flutter/issues/951 , it is mentioned to use following code to setup proxy in GraphQL :

HttpClient httpClient = HttpClient(); httpClient.findProxy = (uri) { return "PROXY localhost:3128;"; }; var link = HttpLink(baseUrl, httpClient: httpClient); var client = GraphQLClient( cache: GraphQLCache(), link: link, );

While implementing this, I constantly keep on getting the following error : The argument type 'HttpClient' can't be assigned to the parameter type 'Client?'

Please look into this and help me with a solution that works

convert HttpClient to IOClient will solve this problem.

import "package:http/io_client.dart";

HttpClient httpClient = HttpClient();

httpClient.findProxy = (uri) {
  return "PROXY $proxy;";
};

// Pass your newly instantiated HttpClient to http.IOClient.
return IOClient(httpClient);
