RawDatagramSocket class
An unbuffered interface to a UDP socket.
The raw datagram socket delivers the datagrams in the same chunks as the underlying operating system. It's a Stream of RawSocketEvents.
Note that the event RawSocketEvent.readClosed will never be received as an UDP socket cannot be closed by a remote peer.
It is not the same as a POSIX raw socket.

Methods
- any(bool test(RawSocketEvent element)) → Future<bool>
inherited
- Checks whether
test accepts any element provided by this stream. - asBroadcastStream({void onListen(StreamSubscription<RawSocketEvent> subscription)?, void onCancel(StreamSubscription<RawSocketEvent> subscription)?}) → Stream<RawSocketEvent>
inherited

inherited
- Creates a new stream with each data event of this stream asynchronously mapped to a new event.

inherited
- Adapt this stream to be a
Stream<R>. - close() → void

inherited
- Returns whether
needle occurs in the elements provided by this stream. - distinct([bool equals(RawSocketEvent previous, RawSocketEvent next)?]) → Stream<RawSocketEvent>
inherited
- Skips data events if they are equal to the previous data event.
