        items: <BottomNavigationBarItem>[
          BottomNavigationBarItem(icon: Icon(IconData(0xF38F, fontFamily: "CupertinoIcons", fontPackage: CupertinoIcons.iconFontPackage)), title: Text("Início")),
          BottomNavigationBarItem(icon: Icon(IconData(0xF2D1, fontFamily: "CupertinoIcons", fontPackage: CupertinoIcons.iconFontPackage)), title: Text("Calendário")),
          BottomNavigationBarItem(icon: Icon(IconData(0xF3A0, fontFamily: "CupertinoIcons", fontPackage: CupertinoIcons.iconFontPackage)), title: Text("Perfil")),
        ],
        currentIndex: _selectedIndex,
        onTap: (int index){
          setState(() {

            setState(() {
              _selectedIndex = index;
            });
        },
      ),
    tabBuilder: (BuildContext context, int index){
      return CupertinoTabView(
        builder: (BuildContext context){
          return Container(
          );
        },
      );
    },
    ),
