Constructors

hashCode → int: The hash code for this object.
read-onlyinherited
runtimeType → Type: A representation of the runtime type of the object.

noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
onByteArrayMessage(Uint8List message) → void: Invoked when a binary (type 0x2) message has been received.
onError(Exception exception) → void: Invoked when error occurs in transport between dart and platform.
onStringMessage(String message) → void: Invoked when a text (type 0x1) message has been received.
onWsClosed(int code, String reason) → void: Invoked when both peers have indicated that no more messages will be transmitted and the connection has been successfully released. No further send/receive calls is possible. All resources like WebSocketConnection should be released after this.
onWsClosing(int code, String reason) → void: Invoked when the remote peer has indicated that no more incoming messages will be transmitted. All resources like WebSocketConnection should be released after this.
onWsOpened(WebSocketConnection webSocketConnection) → void: Invoked when a web socket has been accepted by the remote peer and may begin transmitting messages. Only after this method is invoked, client is able to send/receive ws messages. Returned WebSocketConnection can be used to send text/byte messages to server as long as connection is still active (unless onWsClosing or onWsClosed are called)
toString() → String: A string representation of this object.
