Flutter Bottom Navigation View - AndroidCoding.in

In your main.dart First return a MaterialApp in your build method

@override
Widget build(BuildContext context) {
return MaterialApp(
debugShowCheckedModeBanner: false,
title: 'Professnow',
home: MyBottomNavigationButton(),
routes: <String, WidgetBuilder>{
'/home': (BuildContext context) => Homepage(),
'/profile': (BuildContext context) => Profile(),
'/account': (BuildContext context) => Account(),
'/details': (BuildContext context) => CurrentBookingDetails(),
},
);
}

In the next page or on the same page initialize a new stateful widget with the same name you assigned in your body of the MaterialApp

class MyBottomNavigationButton extends StatefulWidget {
@override
_MyBottomNavigationButtonState createState() =>
_MyBottomNavigationButtonState();
}
class _MyBottomNavigationButtonState extends State<MyBottomNavigationButton> {
int _currentIndex = 0;
final List<Widget> _children = [
MyHomePage(),
Account(),
Profile()
];
@override
Widget build(BuildContext context) {
return Scaffold(
body: _children[_currentIndex],
bottomNavigationBar: BottomNavigationBar(
// type: BottomNavigationBarType.fixed,
onTap: onTapBar,
currentIndex: _currentIndex,
items: [
BottomNavigationBarItem(
icon: Icon(Icons.home),
// ignore: deprecated_member_use
title: Text('MyHomePage'),
),
BottomNavigationBarItem(
icon: Icon(Icons.library_books_rounded),
// ignore: deprecated_member_use
title: Text('Account'),
),
BottomNavigationBarItem(
icon: Icon(Icons.account_circle),
// ignore: deprecated_member_use
title: Text('Profile'),
)
],
),
);
}
