The Drawer Manager class has the ability to swap Scaffold body contents, using a custom provider

    const drawerSelections = [
      HelloPage(),
      CounterPage(),
      TheMACPage()
    ];

    final manager = Provider.of<DrawerManagerProvider>(context, listen: false);

    return Scaffold(
        appBar: AppBar(title: "Some App Bar Title"),
        body: manager.body,
        drawer: DrawerManager(
            ...
            tileSelections: drawerSelections
        )
    )

  @override
  Widget build(BuildContext context) {
    return ChangeNotifierProvider<DrawerManagerProvider>(
        create: (_) => DrawerManagerProvider(),
        child: MaterialApp(
          title: 'Flutter Demo',
          theme: ThemeData(primarySwatch: Colors.blue),
          home: const MyHomePage(),
        )
    );
  }

    const drawerSelections = [
      HelloPage(),
      CounterPage(),
      TheMACPage()
    ];

        drawer: DrawerManager(

            drawerElements: [
                const DrawerHeader(
