How to route from notification in flutter app? - flutter

Question

I am using awesome_notification package for the notifications.
Actually, I have a custom bottom navigation bar and I am using screen[selectedIndex] to change the content of the body inside the scaffold. I guess that is what causing all the problem. Please suggest me a way out.
Whenever I am trying to navigate from my notification I am getting this error.
The code:
// ignore_for_file: use_key_in_widget_constructors
import 'package:awesome_notifications/awesome_notifications.dart';
import 'package:flutter/material.dart';
import 'package:notiminder/pages/done.dart';
import 'package:notiminder/pages/history.dart';
import 'package:notiminder/pages/reminder.dart';
class HomePage extends StatefulWidget {
#override
State<HomePage> createState() => _HomePageState();
}
class _HomePageState extends State<HomePage> {
#override
void initState() {
super.initState();
AwesomeNotifications().isNotificationAllowed().then((isAllowed) {
if (!isAllowed) {
showDialog(
context: context,
builder: (context) => AlertDialog(
title: const Text(
'Allow Notifications',
),
content: const Text(
'Notiminder app would like to send you notifications',
),
actions: [
TextButton(
onPressed: () {
Navigator.pop(context);
},
child: const Text("Don't Allow"),
),
TextButton(
onPressed: () => AwesomeNotifications()
.requestPermissionToSendNotifications()
.then(
(_) => Navigator.pop(context),
),
child: const Text(
'Allow',
style: TextStyle(
fontStyle: FontStyle.italic,
color: Colors.teal,
),
),
),
],
),
);
}
});
AwesomeNotifications().createdStream.listen((notification) {
ScaffoldMessenger.of(context).showSnackBar(
const SnackBar(
content: Text('Reminder created for you'),
),
);
});
AwesomeNotifications().actionStream.listen((event) {
Navigator.pushAndRemoveUntil(
context,
MaterialPageRoute(
builder: (_) => HomePage(),
),
(route) => route.settings.name == screen[1].toString(),
// (route) => route.isFirst,
);
});
}
int selectedIndex = 0;
final screen = [
ReminderPage(),
DonePage(),
HistoryPage(),
];
#override
Widget build(BuildContext context) {
final Size size = MediaQuery.of(context).size;
return GestureDetector(
onTap: () {
final FocusScopeNode currentFocus = FocusScope.of(context);
if (!currentFocus.hasPrimaryFocus) {
currentFocus.unfocus();
}
},
child: SafeArea(
child: Scaffold(
// resizeToAvoidBottomInset: false,
appBar: AppBar(
title: const Text('Notiminder'),
centerTitle: true,
),
body: screen[selectedIndex],
bottomNavigationBar: Row(
children: [
SizedBox(
width: size.width,
height: 80,
child: Stack(
children: [
CustomPaint(
size: Size(size.width, 80),
painter: BNBCustomPainter(),
),
Center(
heightFactor: 0.6,
child: FloatingActionButton(
onPressed: () {
setState(() {
selectedIndex = 0;
});
},
child: const Icon(Icons.notifications, size: 30),
),
),
SizedBox(
width: size.width,
height: 80,
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: [
buttomBarItems(
Icons.done_outline_rounded,
1,
),
Container(
width: size.width * 0.20,
),
buttomBarItems(
Icons.history_rounded,
2,
),
],
),
),
],
),
),
],
),
),
),
);
}
Specifically the notification route:
AwesomeNotifications().actionStream.listen((event) {
Navigator.pushAndRemoveUntil(
context,
MaterialPageRoute(
builder: (_) => HomePage(),
),
(route) => route.settings.name == screen[1].toString(),
// (route) => route.isFirst,
);
});
}
