Flutter:如何用GetxController控制PageView？

dependencies:
  flutter:
    sdk: flutter
  get: ^4.1.4

import 'package:get/get.dart';

class PageViewController extends GetxController {
  // 在这里定义控制器的状态和逻辑
}

import 'package:flutter/material.dart';
import 'package:get/get.dart';

class MyPage extends StatelessWidget {
  final PageViewController controller = Get.put(PageViewController());

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('PageView with GetX'),
      ),
      body: GetBuilder<PageViewController>(
        builder: (controller) {
          return PageView(
            controller: PageController(initialPage: controller.currentPage.value),
            onPageChanged: (index) {
              controller.currentPage.value = index;
            },
            children: [
              // 页面内容
            ],
          );
        },
      ),
    );
  }
}
