onOpen property

Stream<SockJSOpenEvent> onOpen

A stream that can be listened to in order to know when this SockJS Client has successfully connected to the server.

Only a single SockJSOpenEvent will be emitted from this stream unless a connection cannot be made, in which case no events will be emitted at all.

The event will include the selected transport as well as the server URL.

Implementation

Stream<SockJSOpenEvent> get onOpen => _onOpenController.stream;
