In Flutter How do you navigate to a different page and click on a button to navigate to a specfic bottomnavigationtab? I am using Gnav

I am trying to understand how to return to a specific bottomtabindex. As of now I used a hacky way of ading an index to the HomePage as you can see. The issue is I cannot pass the Game object to HomePage too because it feels anti pattern. The Game Object should be passed to the Game Widget/screen
class HomePage extends StatefulWidget {
final int? index;
const HomePage({Key? key, this.index}) : super(key: key);
#override
State<HomePage> createState() => _HomePageState();
}
class _HomePageState extends State<HomePage> {
#override
void initState() {
super.initState();
_selectedIndex = widget.index?? 0;
}
int _selectedIndex = 0;
void _navigateBottomBar(int index) {
setState(() {
_selectedIndex = index;
});
}
List<Widget> screens = [
GameHistory(),
Game(),
Statistics(),
Help()
];
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Row(
children: <Widget>[
Image.asset("assets/images/logo.png", width: 50, height:50),
const Text("App")
],
),
backgroundColor: Colors.deepPurple,
elevation: 10.0,
actions: [
IconButton(
icon: const Icon(Icons.add_circle_outline),
onPressed: () {
Navigator.push(
context,
MaterialPageRoute(builder: (context) => const CreateGame()),
);
},
)
],
),
body: screens[_selectedIndex],
bottomNavigationBar: Container(
color: Colors.black,
padding: const EdgeInsets.symmetric(horizontal: 15.0, vertical: 20),
child: GNav(
selectedIndex: _selectedIndex,
onTabChange: _navigateBottomBar,
backgroundColor: Colors.black,

GButton(icon: Icons.leaderboard_outlined, text: 'Statistics'),
GButton(icon: Icons.help_outline_rounded, text: 'Rules'),
],),
),
);
}
}
//create game widget

How can i navigate to several new pages using the bottom navigation bar in flutter?

I want to navigate to several new pages using my bottom navigation bar in flutter.
I tried several methods to achieve my requirement. But still neither of them worked out for me. I have attached my relevant entire source code below for a better understanding.
Thank you in advance. :)
Dart Source Code :
class dashboard extends StatefulWidget {
#override
_dashboardState createState() => _dashboardState();
}
// ignore: camel_case_types
class _dashboardState extends State<dashboard> {
#override
Widget build(BuildContext context) {
final authService = Provider.of<AuthService>(context);
return Scaffold(
body: SingleChildScrollView(
child: Column(
children: <Widget>[
Padding(
padding: const EdgeInsets.only(top: 80.0, right: 250),
child: Center(
child: Container(
width: 200.0,
height: 20.0,
decoration:
BoxDecoration(borderRadius: BorderRadius.circular(15.0)),
child: (const Text(
'Hello',
textAlign: TextAlign.center,
style: TextStyle(
fontWeight: FontWeight.bold, color: Colors.black),
)),
),
),
),
Padding(
padding: const EdgeInsets.only(top: 20.0),
child: MaterialButton(
onPressed: () {
Navigator.push(context,
MaterialPageRoute(builder: (context) => profile()));
},
child: const Text('Test'),
),
),
Padding(
padding: EdgeInsets.only(left: 300.0, top: 10.0),
child: IconButton(
icon: new Icon(Icons.notifications),
onPressed: () {
Navigator.push(
context,
MaterialPageRoute(
builder: (context) => Notifications(),
),
);
},
),
),
Padding(
padding: const EdgeInsets.only(top: 1.0),
child: Center(
child: Container(
width: 390,
height: 450,
decoration: BoxDecoration(
color: Colors.green.shade100,
borderRadius: BorderRadius.circular(10.0)),
),
),
),
],
),
),
floatingActionButton: FloatingActionButton(onPressed: () async {
await authService.signOut();
}),
// : _children[_currentIndex],
bottomNavigationBar: BottomNavigationBar(
type: BottomNavigationBarType.fixed,
items: const [
BottomNavigationBarItem(
icon: Icon(Icons.book_online),
label: 'Page 1',
),
BottomNavigationBarItem(
icon: Icon(Icons.read_more),
label: 'Page 2',
),
BottomNavigationBarItem(
icon: Icon(Icons.account_circle),
label: 'Page 3',
),
],
),
);
}
}

There are many propositions, this is one :
first, you begin by adding a variable index to know where you are. then add a function to change the content of this variable.
class _dashboardState extends State< dashboard > {
int currentIndex = 1;
changeIndex(index) {
setState(() {
currentIndex = index;
});
}
#override
Widget build(BuildContext context) {
return Scaffold(
body: WillPopScope(
child: (currentIndex == 1)
? HomeScreen()
: (currentIndex == 2)
? Screen2()
: (currentIndex == 3)
? Screen3()
: Settings(),
onWillPop: () async {
bool backStatus = onWillPop();
if (backStatus) {
exit(0);
}
return false;
},
),
then link it to the navbar button.
bottomNavigationBar: BottomNavigationBar(
type: BottomNavigationBarType.fixed,
items: const [
InkWell(
onTap: () => changeIndex(1),
child: BottomNavigationBarItem(
icon: Icon(Icons.book_online),
label: 'Page 1',
),
.....
],
),

the return type 'future<bool>' isn't a 'Future<bool>', as required by the closure context

I'm building my quiz app and my quizpage is taking solid shape but here's a problem i have. I added a Willpopscope just so that my users can't go back to the beginning when the quiz has started and it brings up a dialog box. Here's the code:
import 'dart:convert';
//import 'dart:async';
import 'package:flutter/material.dart';
import 'package:flutter/services.dart';
class GetJson extends StatelessWidget {
const GetJson({Key? key}) : super(key: key);
#override
Widget build(BuildContext context) {
return FutureBuilder(
future: DefaultAssetBundle.of(context).loadString("assets/python.json"),
builder: (context, snapshot) {
var mydata = jsonDecode(snapshot.data.toString());
if (mydata == null) {
return Scaffold(
body: Center(
child: Text(
"Loading",
),
),
);
} else {
return QuizPage();
}
},
);
}
}
class QuizPage extends StatefulWidget {
QuizPage({Key? key}) : super(key: key);
#override
_QuizPageState createState() => _QuizPageState();
}
class _QuizPageState extends State<QuizPage> {
Widget choicebutton() {
return Padding(
padding: EdgeInsets.symmetric(
vertical: 10.0,
horizontal: 20.0,
),
child: MaterialButton(
onPressed: () {},
child: Text(
"option 1",
style: TextStyle(
color: Colors.white,
fontFamily: "Alike",
fontSize: 16.0,
),
maxLines: 1,
),
color: Colors.indigo,
splashColor: Colors.indigo[700],
highlightColor: Colors.indigo[700],
minWidth: 200.0,
height: 45.0,
shape:
RoundedRectangleBorder(borderRadius: BorderRadius.circular(20.0)),
),
);
}
#override
Widget build(BuildContext context) {
SystemChrome.setPreferredOrientations(
[DeviceOrientation.portraitDown, DeviceOrientation.portraitUp]);
return WillPopScope(
onWillPop: () {
return showDialog(
context: context,
builder: (context) => AlertDialog(
title: Text(
"Quizstar",
),
content: Text("You Can't Go Back At This Stage"),
actions: [
// ignore: deprecated_member_use
FlatButton(onPressed: () {
Navigator.of(context).pop();
},
child: Text(
"Ok",
),
)
],
)
);
},
child: Scaffold(
body: Column(
children: [
Expanded(
flex: 3,
child: Container(
padding: EdgeInsets.all(15.0),
alignment: Alignment.bottomLeft,
child: Text(
"This is a sample question which will be displayed?",
style: TextStyle(
fontSize: 16.0,
fontFamily: "Quando",
),
),
),
),
Expanded(
flex: 6,
child: Container(
child: Column(
mainAxisAlignment: MainAxisAlignment.spaceAround,
children: [
choicebutton(),
choicebutton(),
choicebutton(),
choicebutton(),
],
),
),
),
Expanded(
flex: 1,
child: Container(
alignment: Alignment.topCenter,
child: Center(
child: Text(
"30",
style: TextStyle(
fontSize: 35.0,
fontWeight: FontWeight.w700,
fontFamily: "Times New Roman",
),
),
),
),
),
],
),
),
);
}
}
The error is in the showDialog() but i can't seem to figure it out.
Thanks a lot guys.

This might help
On your willpop scope function do this instead
onWillPop: () {
showDialog(
context: context,
builder: (context) => AlertDialog(
title: Text(
"Quizstar",
),
content: Text("You Can't Go Back At This Stage"),
actions: [
// ignore: deprecated_member_use
FlatButton(onPressed: () {
Navigator.of(context).pop();
},
child: Text(
"Ok",
),
)
],
)
);
return true;
),
child : your widget

Okay i figured it out
return WillPopScope(
onWillPop: () async {
print("Back Button Pressed");
final shouldPop = await showWarning(context);
return shouldPop ?? false;
},
Then i went ahead to define showWarning like this, then defined my dialog box inside it:
Future<bool?> showWarning(BuildContext context) async => showDialog<bool>(
context: context,
builder: (context) => AlertDialog(
title: Text("Quizstar"),
content: Text("You cannot go back at this stage"),
actions: [
ElevatedButton(
onPressed: () => Navigator.pop(context, false),
child: Text("Okay"),
),
//ElevatedButton(
// onPressed: () => Navigator.pop(context, true),
// child: Text("Yes"),
//),
],
),
);
Tips: Don't forget to make the future a bool by writing inside it with it's '?'

How to pass data/Images from one page to another in Bottom Navigation Bar

I wanted to send Data/images from one page to another. In the Homepage when I tap on the add Icon button image should be passed to the Cart page and if the icon is tapped again image is removed from the Cart page. But, the cart page should be accessed from bottom navigation bar.
but it is showing an error called 1 positional argument(s) expected, but 0 found.
Try adding the missing arguments.. when it calls the cart page.

Yep, it will throw an error because the constructor of the Cart class is expecting one parameter to be passed in. You could use a named constructor instead like this:
class Cart extends StatefulWidget {
final List<Dish> _cart;
Cart(this._cart);
That way, you can call it like so:
Cart(cart: _cartList),
But if you actually need the cart list, I would recommend that you write a provider to keep track of the cart data across screens.

Flutter ListView on click navigate to another screen

I'm learning Flutter. I have a ListView and I would like to make the list items clickable. My idea is that when the user clicks on an item, it will be directed to another screen. Each buttom should leads to different screen. I'm having trouble implementing it, I don't know what to use: gesture detector or ontap. What should I do? Should I use ListTile instead of ListView?
class MyApp extends StatelessWidget {
#override
Widget build(BuildContext context) {
final title = "ListView List";
return MaterialApp(
title: title,
home: Scaffold(appBar: AppBar(
title: Text(title),
),
body: new ListView(
shrinkWrap: true,
padding: const EdgeInsets.all(20.0),
children: List.generate(choices.length, (index) {
return Center(
child: ChoiceCard(choice: choices[index], item: choices[index]),
);
}
)
)
)
);
}
}
class Choice {
const Choice({this.title, this.icon});
final String title;
final IconData icon;
}
const List<Choice> choices = const <Choice>[
const Choice(title: 'This is a Car', icon: Icons.directions_car),
const Choice(title: 'This is a Bicycle', icon: Icons.directions_bike),
const Choice(title: 'This is a Boat', icon: Icons.directions_boat),
const Choice(title: 'This is a Bus', icon: Icons.directions_bus),
const Choice(title: 'This is a Train', icon: Icons.directions_railway),
];
class ChoiceCard extends StatelessWidget {
const ChoiceCard(
{Key key, this.choice, this.onTap, #required this.item, this.selected: false}
) : super(key: key);
final Choice choice;
final VoidCallback onTap;
final Choice item;
final bool selected;
#override
Widget build(BuildContext context) {
TextStyle textStyle = Theme.of(context).textTheme.display1;
if (selected)
textStyle = textStyle.copyWith(color: Colors.lightGreenAccent[400]);
return Card(
color: Colors.white,
child: Row(
children: <Widget>[
new Container(
padding: const EdgeInsets.all(8.0),
alignment: Alignment.topLeft,
child: Icon(choice.icon, size:80.0, color: textStyle.color,)),
new Expanded(
child: new Container(
padding: const EdgeInsets.all(10.0),
alignment: Alignment.topLeft,
child:
Text(choice.title, style: null, textAlign: TextAlign.left, maxLines: 5,),
)
),
],
crossAxisAlignment: CrossAxisAlignment.start,
)
);
}
}

You can copy paste run full code below
Step 1: To allow Navigator.push work, you can move MaterialApp to upper level
Step 2: In onTap pass Navigator.push
ChoiceCard(
choice: choices[index],
item: choices[index],
onTap: () {
Navigator.push(
context,
MaterialPageRoute(
builder: (context) => Detail(choice: choices[index])),
);
},
),
Step 3: Wrap Card with InkWell and call onTap()
return InkWell(
onTap: () {
onTap();
},
child: Card(
