Socket class

A TCP connection between two sockets.

A socket connection connects a local socket to a remote socket. Data, as Uint8Lists, is received by the local socket, made available by the Stream interface of this class, and can be sent to the remote socket through the IOSink interface of this class.

Static Methods

connect(dynamic host, int port, {dynamic sourceAddress, int sourcePort = 0, Duration? timeout}) → Future<Socket>: Creates a new socket connection to the host and port and returns a Future that will complete with either a Socket once connected or an error if the host-lookup or connection failed.
