# connectSync method Null safety

RawSynchronousSocket connectSync (

1. dynamic host,
2. int port

)

Creates a new socket connection and returns a RawSynchronousSocket.

`host` can either be a String or an InternetAddress. If `host` is a String, connectSync 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.

## Implementation

    external static RawSynchronousSocket connectSync(host, int port);
