• For iOS do flutter build ios –release and then open/run the project in Xcode
• For Android do flutter build apk –release and then open/run the project in Android Studio

You can also Globally overrode the HttpClient:

class MyHttpOverrides extends HttpOverrides {
  @override
  HttpClient createHttpClient(SecurityContext context) {
    return super.createHttpClient(context)
        ..maxConnectionsPerHost = 5;
  }
}


void main() {
  HttpOverrides.global = MyHttpOverrides();
  runApp(MyApp());
}

import 'package:http/http.dart' as http;
...
http.Response response =  http.get('url')
