如何使用getx制作摄像头画面？

dependencies:
  flutter:
    sdk: flutter
  get: ^4.1.4

import 'package:get/get.dart';
import 'package:camera/camera.dart';

class CameraController extends GetxController {
  CameraController();

  CameraController get to => Get.find();

  CameraController get cameraController => Get.find();

  Rx<CameraController> _cameraController = Rx<CameraController>();

  CameraController get value => _cameraController.value;

  set cameraController(CameraController value) {
    _cameraController.value = value;
  }

  @override
  void onInit() {
    super.onInit();
    initializeCamera();
  }

  Future<void> initializeCamera() async {
    final cameras = await availableCameras();
    final camera = cameras.first;
    cameraController = CameraController(
      camera,
      ResolutionPreset.medium,
    );
    await cameraController.initialize();
  }

  @override
  void onClose() {
    super.onClose();
    cameraController?.dispose();
  }
}

class CameraPage extends StatelessWidget {
  final CameraController cameraController = Get.put(CameraController());

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Camera Page'),
      ),
      body: Center(
        child: Obx(
          () => cameraController.value.isInitialized
              ? CameraPreview(cameraController.value)
              : CircularProgressIndicator(),
        ),
      ),
    );
  }
}

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