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.
Constructors
Properties
- address → InternetAddress
-
Returns the address used by this socket.
read-only - broadcastEnabled → bool
-
Set or get, whether IPv4 broadcast is enabled.
read / write - multicastHops → int
-
Set or get, the maximum network hops for multicast packages originating from this socket.
read / write - multicastInterface → NetworkInterface
-
Set or get, the network interface used for outgoing multicast packages.
read / write - multicastLoopback → bool
-
Set or get, whether multicast traffic is looped back to the host.
read / write - port → int
-
Returns the port used by this socket.
read-only - readEventsEnabled → bool
-
Set or get, if the RawDatagramSocket should listen for RawSocketEvent.READ events. Default is
true.read / write - writeEventsEnabled → bool
-
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.read / write - first → Future<RawSocketEvent>
-
Returns the first element of the stream.
read-only, inherited - hashCode → int
-
The hash code for this object.
read-only, inherited - isBroadcast → bool
-
Whether this stream is a broadcast stream.
read-only, inherited - isEmpty → Future<bool>
-
Reports whether this stream contains any elements.
read-only, inherited - last → Future<RawSocketEvent>
-
Returns the last element of the stream.
read-only, inherited - length → Future<int>
-
Counts the elements in the stream.
read-only, inherited - runtimeType → Type
-
A representation of the runtime type of the object.
read-only, inherited - single → Future<RawSocketEvent>
-
Returns the single element.
