  class MyApp extends StatelessWidget {
    @override
    Widget build(BuildContext context) {
      return new MaterialApp(
        title: 'Flutter Demo',
        theme: new ThemeData(
          primarySwatch: Colors.blue,
        ),
        home: new Scaffold(
          appBar: new AppBar(
            title: new Text("check"),
          ),
          drawer: XmobeMenu(5),
        ),

      );
    }
  }

  final List menuItems = [
    MenuItem(0,'Home',Icons.home,Icons.chevron_right),
    MenuItem(0,'Home',Icons.home,Icons.chevron_right),
    MenuItem(0,'Home',Icons.home,Icons.chevron_right),
    MenuItem(0,'Home',Icons.home,Icons.chevron_right),

    MenuItem(0,'Home',Icons.home,Icons.chevron_right),
    MenuItem(0,'Home',Icons.home,Icons.chevron_right),

  class XmobeMenu extends StatelessWidget {

    }
    @override
    Widget build(BuildContext context) {
      return Drawer(
        child: ListView.builder(
          itemBuilder: (BuildContext context, int index) {
            return MenuItemWidget(menuItems[index],indexNumber);
          },
          itemCount: menuItems.length,
        ),
      );
    }

  class MenuItem {
    MenuItem(this.itemNumber,this.title, this.leadIcon, this.trailIcon,);
    final int itemNumber;
    final IconData leadIcon;
    final IconData trailIcon;
    final String title;
  }

  class MenuItemWidget extends StatelessWidget {
    final MenuItem item;
    final int indexNumber;
    const MenuItemWidget(this.item, this.indexNumber);

    Widget _buildMenu(MenuItem menuItem, context) {
      return InkWell(
          onTap: () {
            Navigator.of(context).push(
              new MaterialPageRoute(
                builder: (BuildContext context) => MyApp(),
              ),

          },
          child: new Container(
