onRaw abstract method

StreamSubscription onRaw(
  1. dynamic callback(
    1. String data
    )
)

Registers callback as an event handler for the raw event - which is triggered whenever the server socket calls socket.send(...). The object produced will have a 'message' property.

THIS WILL NOT BE CALLED IF THE DATA CANNOT BE JSON-DECODED. You will need to use onMessage for that.

To cancel the callback, you can call .cancel on the returned StreamSubscription.

Implementation

StreamSubscription onRaw(Function(String data) callback);
