如果使用Getx如何构建Navigator()？

dependencies:
  flutter:
    sdk: flutter
  get: ^4.1.4

import 'package:get/get.dart';

class MyController extends GetxController {
  void navigateToNextPage() {
    Get.to(NextPage());
  }
}

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

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('My Page'),
      ),
      body: Center(
        child: GetBuilder<MyController>(
          builder: (_) => RaisedButton(
            child: Text('Next Page'),
            onPressed: controller.navigateToNextPage,
          ),
        ),
      ),
    );
  }
}
