RawDatagramSocket class Null safety
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.
