如何使用getx在flutter中显示websocket数据

import 'package:get/get.dart';
import 'package:web_socket_channel/io.dart';

final channel = IOWebSocketChannel.connect('wss://your_websocket_url');

class WebSocketController extends GetxController {
  var message = ''.obs;

  @override
  void onInit() {
    super.onInit();
    channel.stream.listen((data) {
      message.value = data;
    });
  }
}

class WebSocketPage extends StatelessWidget {
  final controller = Get.put(WebSocketController());

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('WebSocket Data'),
      ),
      body: Center(
        child: Obx(() => Text(controller.message.value)),
      ),
    );
  }
}

void main() {
  runApp(GetMaterialApp(
    home: WebSocketPage(),
  ));
}
