# connect method Null safety

Future<RawSocket> connect (

1. dynamic host,
2. int port,
3. {dynamic sourceAddress,
4. Duration? timeout}

)

Creates a new socket connection to the host and port and returns a Future that will complete with either a RawSocket once connected or an error if the host-lookup or connection failed.

`host` can either be a String or an InternetAddress. If `host` is a String, connect will perform a InternetAddress.lookup and try all returned InternetAddresses, until connected. Unless a connection was established, the error from the first failing connection is returned.

The argument `sourceAddress` can be used to specify the local address to bind when making the connection. `sourceAddress` can either be a `String` or an `InternetAddress`. If a `String` is passed it must hold a numeric IP address.

The argument `timeout` is used to specify the maximum allowed time to wait for a connection to be established. If `timeout` is longer than the system level timeout duration, a timeout may occur sooner than specified in `timeout`. On timeout, a SocketException is thrown and all ongoing connection attempts to `host` are cancelled.

## Implementation

    external static Future<RawSocket> connect(host, int port,
        {sourceAddress, Duration? timeout});
