//为了支持鼠标滑动，我们需要通过以下步骤更改应用程序的默认滚动行为：

//1-创建一个类，从MaterialScrollBeavior扩展它并覆盖dragDevices

//2-将AppScrollBehavior实例传递给MaterialApp的scrollBehavior属性：

class MyCustomScrollBehavior extends MaterialScrollBehavior {

  // Override behavior methods and getters like dragDevices

  Set<PointerDeviceKind> get dragDevices => {

        PointerDeviceKind.touch,

        PointerDeviceKind.mouse,

      };

}

// 在整个应用顶层使用AppScrollBehavior

class MyApp extends StatelessWidget {

  const MyApp({super.key});

  @override

  Widget build(BuildContext context) {

    return MaterialApp(

      debugShowCheckedModeBanner: false,

      title: "flutterDemo",

      theme: ThemeData(

        primarySwatch: Colors.blue,

      ),

      home: const HomePage(),

      scrollBehavior: MyCustomScrollBehavior(),

    );

  }

}

// 在小部件中使用

// ScrollBehavior can be set for a specific widget.

final ScrollController controller = ScrollController();

ScrollConfiguration(

  behavior: MyCustomScrollBehavior(),

  child: ListView.builder(

    controller: controller,

    itemBuilder: (BuildContext context, int index) {

     return Text('Item $index');

    }

  ),

);
