The RawDatagramSocket is a low-level interface to an UDP socket, exposing the raw events signaled by the system. It's a Stream of RawSocketEvents.
Note that the event RawSocketEvent.READ_CLOSED will never be received as an UDP socket cannot be closed by a remote peer.

Static Methods
-
bind(
host, int port, {bool reuseAddress: true}) → Future<RawDatagramSocket> -
Creates a new raw datagram socket binding it to an address and port.
Properties
- address → InternetAddress

read-only
Returns the address used by this socket.

- readEventsEnabled → bool
-
read / write
Set or get, if the RawDatagramSocket should listen for RawSocketEvent.READ events. Default is
true
. - single → Future<RawSocketEvent>
-
read-only, inherited
Returns the single element.…
- writeEventsEnabled → bool
-
read / write
Set or get, if the RawDatagramSocket should listen for RawSocketEvent.WRITE events. Default is
true
. This is a one-shot listener, and writeEventsEnabled must be set to true again to receive another write event.
