       body: Stack(
         children: <Widget>[
           Container(
             decoration: BoxDecoration(
               image: DecorationImage(
                   image: AssetImage('assets/background.jpg'),
                   fit: BoxFit.cover),
             ),
           ),
           Align(
               alignment: Alignment.bottomCenter,
               child: Theme(
                   data: Theme.of(context)
                       .copyWith(canvasColor: Colors.transparent),
                   child: BottomNavigationBar(
                     currentIndex: 0,
                     items: [
                       BottomNavigationBarItem(
                           icon: Icon(Icons.home), title: Text('Home')),
                       BottomNavigationBarItem(
                           icon: Icon(Icons.home), title: Text('Home')),
                       BottomNavigationBarItem(
                           icon: Icon(Icons.home), title: Text('Home'))
                     ],
                   ))),
         ],
       ),
     ),

void main() {
  SystemChrome.setEnabledSystemUIOverlays([SystemUiOverlay.bottom]);
  runApp(MaterialApp(
     home: MyApp()));
}

@override
Widget build(BuildContext context) {
  return Scaffold(

        Container(
         child: Image.network("https://picsum.photos/660/1420"),
        ),
        Align(
            alignment: Alignment.bottomCenter,
            child: BottomNavigationBar(
              backgroundColor: Colors.black.withOpacity(0.1), //here set your transparent level
              elevation: 0,
              selectedItemColor:  Colors.blueAccent,
              unselectedItemColor: Colors.white,
              type: BottomNavigationBarType.fixed,
              currentIndex: 0,
              showSelectedLabels: false,
              showUnselectedLabels: false,
              items: [
                BottomNavigationBarItem(
                    icon: Icon(Icons.notifications_none, size: 30), title: Text('Notifications')),
                BottomNavigationBarItem(
                    icon: Icon(Icons.search, size: 30), title: Text('Search')),
                BottomNavigationBarItem(
                    icon: Icon(Icons.perm_identity, size: 30), title: Text('User'))
              ],
