dispose method

@override Future<void> dispose()

Releases all resources. The client must not be used after this call.

Closes streams, cancels timers, and disposes the underlying HTTP / WS clients. Idempotent: a second call is a no-op. Any method invoked after dispose returns a failure or throws — treat the instance as dead.

Implementation

@override
Future<void> dispose() async {
  await _eventController.close();
  await _stateController.close();
}
