RawSocket class Null safety

A TCP connection.

A socket connection connects a local socket to a remote socket. Data, as Uint8Lists, is received by the local socket and made available by the read method, and can be sent to the remote socket through the write method.

The Stream interface of this class provides event notification about when a certain change has happened, for example when data has become available (RawSocketEvent.read) or when the remote end has stopped listening (RawSocketEvent.closed).

Properties

address → InternetAddress: The InternetAddress used to connect this socket.
read-only
first → Future<RawSocketEvent>: The first element of this stream.
read-onlyinherited
hashCode → int: The hash code for this object.
read-onlyinherited
isBroadcast → bool: Whether this stream is a broadcast stream.
read-onlyinherited
isEmpty → Future<bool>: Whether this stream contains any elements.
read-onlyinherited
last → Future<RawSocketEvent>: The last element of this stream.
read-onlyinherited
length → Future<int>: The number of elements in this stream.
read-onlyinherited
port → int: The port used by this socket.
read-only
readEventsEnabled ↔ bool: Set or get, if the RawSocket should listen for RawSocketEvent.read events. Default is true.
read / write
remoteAddress → InternetAddress: The remote InternetAddress connected to by this socket.
read-only
remotePort → int: The remote port connected to by this socket.
read-only
runtimeType → Type: A representation of the runtime type of the object.
read-onlyinherited
single → Future<RawSocketEvent>: The single element of this stream.
read-onlyinherited
writeEventsEnabled ↔ bool: Set or get, if the RawSocket 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
