How to navigate to sibling item in Flutter Cupertino Bottom Navigation Bar - flutter

Question

I'm using Cupertino design in Flutter and using CupertinoTabBar. I want to visit to different tab item when coming from different screen.
For example, I've 2 items: Home and Profile. CupertinoTabBar is defined in main screen. From HomeScreen, I want to have a button to visit ProfileScreen tab. How to navigate in this situation?
import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';
class MainScreen extends StatefulWidget {
#override
State<StatefulWidget> createState() {
return _MainScreenState();
}
}
class _MainScreenState extends State<MainScreen> {
#override
Widget build(BuildContext context) {
return Material(
child: CupertinoTabScaffold(
tabBar: CupertinoTabBar(
items: const <BottomNavigationBarItem>[
BottomNavigationBarItem(
icon: Icon(Icons.home),
title: Text("Home")
),
BottomNavigationBarItem(
icon: Icon(Icons.user),
title: Text("My Appointments")
)
],
),
tabBuilder: (BuildContext context, int index) {
switch (index) {
case 0:
return CupertinoTabView(
builder: (BuildContext context) {
return HomeScreen();
},
defaultTitle: 'Home',
);
break;
case 1:
return CupertinoTabView(
builder: (BuildContext context) => ProfileScreen(),
defaultTitle: 'Profile',
);
break;
}
return null;
},
),
);
}
}
class HomeScreen extends StatefulWidget {
#override
State<StatefulWidget> createState() {
return Container(
child: CupertinoButton(
child: Text("Check Profile"),
onPressed: () {
// Pop this page and Navigate to Profile page
},
)
);
}
}
class ProfileScreen extends StatefulWidget {
#override
State<StatefulWidget> createState() {
return Container(
child: Text("Profile")
);
}
}

Maybe can help you
int currentTabIndex = 0;
onTapped(int index) {
setState(() {
currentTabIndex = index;
});
}
List<Widget> tabs = [
InicioPage(),
OfertasPage(),
FavoritosPage(),
Login(),
];
tabBuilder: (context, index) {
switch (index) {
case 0:
return InicioPage();
break;
case 1:
return OfertasPage();
break;
case 2:
return FavoritosPage();
break;
case 3:
return Login();
default:
return InicioPage();
break;
}
}
