Interceptor for WebSocket messages.
All methods should call next to continue the chain.
Hints:
-
You can send a any type of data, and change its type to a string or a bytes array only at last Interceptor in chain. You can send a Map<String, dynamic> and change it to a string or attach a context to the message.
-
You can log the message and use performance metrics inside Interceptor.
-
You can call "next" once or multiple times or not call it at all to stop the chain.
