Answer 1

很简单，只要让你的右边的内容使用GetMaterialApp，并且路由改变是渲染右边的内容，然后left sidler是一个组件warp你的menuslider，最后控制你左边的slider menuchange index。显示我的代码

 Widget build(BuildContext context) {
    return ScreenUtilInit(
        designSize: const Size(dessignWidth, dessignHeight),
        builder: () => BarcodeKeyboardListener(
            onBarcodeScanned: (String codeValue) {},
            child: Material(
              child: MaterialApp(
                  localizationsDelegates: const [
                    GlobalMaterialLocalizations.delegate,
                    GlobalWidgetsLocalizations.delegate,
                  ],
                  supportedLocales: const [
                    Locale('zh', 'CH'),
                    Locale('en', 'US'),
                  ],
                  home: Row(
                    children: [
                      Material(
                        child: SliderMenu(),
                      ),
                      Expanded(
                          child: GetMaterialApp(
                              debugShowCheckedModeBanner: false,
                              enableLog: true,
                              navigatorKey: Get.key,
                              routingCallback: RouteChangeMiddleWare.observer,
                              logWriterCallback: Logger.write,
                              initialRoute: AppPages.INITIAL,
                              getPages: AppPages.routes,
                              unknownRoute: AppPages.unknownRoute,
                              builder: EasyLoading.init(),
                              onInit: () =>
                                  {logger.v('Global.CONFIG', AppConfig)}))
                    ],
                  )),
            )));
  }```

            onTap: () {
              if (Get.currentRoute == Routes.LISTOFANIMALS) {
                Get.back();
              } else {
                Get.toNamed(Routes.LISTOFANIMALS);
              }
            },
          ),
          ListTile(

          ListTile(
            leading: Icon(Icons.bluetooth),
            title: Text('Conexion BT'),
            onTap: () {
              if (Get.currentRoute == Routes.CONEXIONBT) {
                Get.back();
              } else {
                Get.toNamed(Routes.CONEXIONBT);
              }
            },
          ),
          ListTile(
            leading: Icon(Icons.picture_as_pdf),
            title: Text('Exportar Datos'),
            onTap: () {
              if (Get.currentRoute == Routes.EXPORT) {
                Get.back();
              } else {
                Get.toNamed(Routes.EXPORT);
              }
            },
          ),
          ListTile(

            title: Text('Acerca de'),
            onTap: () {
              if (Get.currentRoute == Routes.ACERCA) {
                Get.back();
              } else {
                Get.toNamed(Routes.ACERCA);
              }
            },
          ),
        ],
      ),
    );
  }
}

家庭部分是：

import 'package:vakuprfid/app/modules/widgets/side_bar.dart';//import widget

class HomeView extends GetView<HomeController> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
        drawer: SideBar(),
        body: ...
      );
   }
}

这是结果：
