you can use a Scaffold property that called persistentFooterButtons, and you can add a widget to it, this is an image of the app https://i.stack.imgur.com/Tb4iA.jpg, and this is the code for making the app.
void main() async {
runApp(MyApp());
}
class MyApp extends StatefulWidget {
const MyApp({Key key}) : super(key: key);
#override
_MyAppState createState() => _MyAppState();
}
class _MyAppState extends State<MyApp> {
int _selectedIndex = 0;
void _onItemTapped(int index) {
setState(() {
_selectedIndex = index;
});
}
static const TextStyle optionStyle =
TextStyle(fontSize: 30, fontWeight: FontWeight.bold);
static const List<Widget> _widgetOptions = <Widget>[
Text(
'Index 0: Home',
style: optionStyle,
),
Text(
'Index 1: Business',
style: optionStyle,
),
Text(
'Index 2: School',
style: optionStyle,
),
];
#override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
body: Container(
color: Colors.white,
),
=================== this is all you need ==============================
persistentFooterButtons: [
Row(
mainAxisAlignment: MainAxisAlignment.spaceAround,
crossAxisAlignment: CrossAxisAlignment.center,
children: [
IconButton(
iconSize: 35,
icon: Icon(Icons.play_arrow),
onPressed: null,
),
Container(child: Text("Some data over hereSome data ")),
IconButton(
icon: Icon(Icons.favorite),
onPressed: null,
)
],
)
],
=================================================
bottomNavigationBar: BottomNavigationBar(
items: const <BottomNavigationBarItem>[
BottomNavigationBarItem(
icon: Icon(Icons.home),
title: Text('Home'),
),
BottomNavigationBarItem(
icon: Icon(Icons.business),
title: Text('Business'),
),
BottomNavigationBarItem(
icon: Icon(Icons.school),
title: Text('School'),
),
],
currentIndex: _selectedIndex,
selectedItemColor: Colors.amber[800],
onTap: _onItemTapped,
),
),
);
}
}

An Expanded Widget should solve your issue. The video and documentation is at the link. It should allow for a row to be placed/pushed to the bottom of the screen so that it is "above" the navigation bar. Simply wrap your widget with an expanded widget.
