Answer 1

Simple create enum class like below.

enum DrawerSelection { home, favorites, settings}

Create enum object and pass pre-defined value if you want, in my case i pass home as selected ListTile item. Like below code.

class _MyHomePage extends State {
DrawerSelection _drawerSelection = DrawerSelection.home;

Then in ListTile use selected property and change enum onTap() like below code.

 ListTile(
              selected: _drawerSelection == DrawerSelection.home,
              title: Text('Home'),
              leading: Icon(Icons.home),
              onTap: () {
                Navigator.pop(context);
                setState(() {
                    _drawerSelection = DrawerSelection.home;
                    _currentWidget = MainWidget();                    
                    _appBarTitle = Text("Home");
                });
              },
            ),
 ListTile(
            selected: _drawerSelection == DrawerSelection.favorites,
            title: Text('Favorites'),
            leading: Icon(Icons.favorite),
            onTap: () {
              Navigator.pop(context);                 
              setState(() {
                  _drawerSelection = DrawerSelection.favorites;                 
                  _currentWidget = FavoritesWidget();                  
                  _appBarTitle = Text("Favorites");
              });
            },
          ),
ListTile(
            selected: _drawerSelection == DrawerSelection.settings,
            title: Text('Settings'),
            leading: Icon(Icons.settings),
            onTap: () {
              Navigator.pop(context);
              setState(() {
                  _drawerSelection = DrawerSelection.settings;                 
                  _currentWidget = SettingsWidget();
                  _appBarTitle = Text("Settings");
              });
            },
          ),
