            child: NavigationRail(
              selectedIndex: _selectedIndex,
              onDestinationSelected: (int index) {
                setState(() {
                  _selectedIndex = index;
                });
              },
              labelType: NavigationRailLabelType.selected,
              destinations: [
                NavigationRailDestination(
                  icon: Icon(Icons.favorite_border),
                  selectedIcon: Icon(Icons.favorite),
                  label: Text('First'),
                ),
                NavigationRailDestination(
                  icon: Icon(Icons.bookmark_border),
                  selectedIcon: Icon(Icons.book),
                  label: Text('Second'),

                  selectedIcon: Icon(Icons.star),
                  label: Text('Third'),
                ),
              ],
            ),
          )
