I have been struggling to figure out how to navigate back to my bottom navigation bar after navigating to a page without it. Using Navigator pop does not work and produces an error, I have looked at other questions where people asked the same thing, but no one seems to answer this question everyone just explains how to navigate between different items within the Navigation Bar... which is easy.
Below is the code of the Navigation bar, which works without any problems. Again I CAN navigate between different Navigation Bar pages easily.
`import 'package:google_nav_bar/google_nav_bar.dart';
import 'package:flutter/material.dart';
import '../../Screens/screens_export.dart';
class GoogleNavBar extends StatefulWidget {
const GoogleNavBar({Key? key}) : super(key: key);
@override
State<GoogleNavBar> createState() => _GoogleNavBarState();
}
class _GoogleNavBarState extends State<GoogleNavBar> {
int currentIndex = 2;
final Screens = [
nderChat(),
TBD(),
Reports(),
Drawer(),
];
@override
Widget build(BuildContext context) {
return Scaffold(
body: Screens[currentIndex],
bottomNavigationBar: Container(
color: Colors.black,
child: Padding(
padding: const EdgeInsets.symmetric(
horizontal: 15,
vertical: 20),
child: GNav(
backgroundColor: Colors.black,
color: Colors.white,
activeColor: Colors.white,
tabBackgroundColor: Colors.grey.shade800,
padding: EdgeInsets.all(16),
gap: 8,
onTabChange: (index) => setState(() => currentIndex = index),
tabs: const[
GButton(
icon: Icons.groups_outlined,
text: 'Global',
),
GButton(
icon: Icons.rss_feed_outlined,
text: 'TBD',
),
GButton(
icon: Icons.running_with_errors_rounded,
text: 'Alerts',
),
// GButton(
// icon: Icons.sports,
// text: 'Reports',
// ),
GButton(
icon: Icons.account_circle_outlined,
text: 'Profile',
),
]
),
),
),
);
}
}
In the Screen Drawer, I open a drawer, which probably isn't a good practice. Clicking one of the Drawer options takes me to another page such as a Profile Page(which is not part of the Nav Bar).
After navigating to Profile, when I do "Navigation Pop" it gives me "route error".
I do not know what to do, I have tried using Pushnamed, but also gave me a error, perhaps I did it wrong.
A similar question which went unanswered : Flutter pass bottom navigation bar selected index when navigating back to page with bottom nav bar
