RawSecureSocket class Null safety

RawSecureSocket provides a secure (SSL or TLS) network connection.

Client connections to a server are provided by calling RawSecureSocket.connect. A secure server, created with RawSecureServerSocket, also returns RawSecureSocket objects representing the server end of a secure connection. The certificate provided by the server is checked using the trusted certificates set in the SecurityContext object. The default SecurityContext object contains a built-in set of trusted root certificates for well-known certificate authorities.

Properties

address InternetAddress
The InternetAddress used to connect this socket.
read-only, inherited
first Future<RawSocketEvent>
The first element of this 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>
Whether this stream contains any elements.
read-only, inherited
last Future<RawSocketEvent>
The last element of this stream.
read-only, inherited
length Future<int>
The number of elements in this stream.
read-only, inherited
peerCertificate X509Certificate?
Get the peer certificate for a connected RawSecureSocket. If this RawSecureSocket is the server end of a secure socket connection, peerCertificate will return the client certificate, or null, if no client certificate was received. If it is the client end, peerCertificate will return the server's certificate.
read-only
port int
The port used by this socket.
read-only, inherited
readEventsEnabled bool
Set or get, if the RawSocket should listen for RawSocketEvent.read events. Default is true.
read / write, inherited
remoteAddress InternetAddress
The remote InternetAddress connected to by this socket.
read-only, inherited
remotePort int
The remote port connected to by this socket.
read-only, inherited
runtimeType Type
A representation of the runtime type of the object.
read-only, inherited
selectedProtocol String?
The protocol which was selected during protocol negotiation.
read-only
single Future<RawSocketEvent>
The single element of this stream.
read-only, inherited
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, inherited
