socketToSocket static method

Future<SocketConnector> socketToSocket({ SocketConnector? connector, required InternetAddress addressA, required int portA, required InternetAddress addressB, required int portB, DataTransformer? transformAtoB, DataTransformer? transformBtoA, bool verbose = false, bool logTraffic = false, Duration timeout = SocketConnector.defaultTimeout, IOSink? logger, })

• Creates socket to portA on addressA
• Creates socket to portB on addressB
• Relays data between the sockets
