connected property

(T? Function(WebSocketChannel socket, Map<String, Object?>? payload)?) connected
final

The first argument is actually the WebSocket, but to avoid bundling DOM typings because the client can run in Node env too, you should assert the websocket type during implementation.

Also, the second argument is the optional payload that the server may send through the ConnectionAck message.

Implementation

final T? Function(WebSocketChannel socket, Map<String, Object?>? payload)?
    connected;
