this is the method to get the data

import 'package:cloud_firestore/cloud_firestore.dart';
import 'package:online_shop/core/services/summer_notifier.dart';
import 'package:online_shop/model/Summer_d_model.dart';
Future getsummerinfo (SummerNotifier summerNotifier) async {
QuerySnapshot snapshot =
await FirebaseFirestore.instance.collection("Summer_D").get();
List<Summer_d> _summerList = [];
snapshot.docs.forEach((docs) {
Summer_d summer_d = Summer_d.fromMap(docs.data() as Map<String, dynamic>);
_summerList.add(summer_d);
});
summerNotifier.summerList = _summerList;
}
this is the other one
// ignore_for_file: unused_local_variable, non_constant_identifier_names
import 'package:cloud_firestore/cloud_firestore.dart';
import 'package:online_shop/core/services/summer_notifier.dart';
import 'package:online_shop/model/Summer_d_model.dart';
Future getsummerinfo (SummerNotifier summerNotifier) async {

snapshot.docs.forEach((docs) {
Summer_d summer_d = Summer_d.fromMap(docs.data() as Map<String, dynamic>);
_summerList.add(summer_d);
});
summerNotifier.summerList = _summerList;
}
this is the models
// ignore_for_file: camel_case_types
class Summer_d {
late String Imag;
late String info;
late String name;
late int price;
late String sub_info;
late List<dynamic>? sub_img;
Summer_d.fromMap(Map<String,dynamic>data){
Imag = data["Imag"];
info = data ["info"];
name = data ["name"];
price = data["price"];
sub_info = data ["sub_info"];
sub_img = data ["sub_img"];
}
}
You're hardcoding the itemCount in the ListView.builder, and then in the ListView.builder, in its itemBuilder method, you're saying summerNotifier.summerList[index]. The index will always be zero.
#override
Widget build(BuildContext context) {
SummerNotifier summerNotifier = Provider.of<SummerNotifier>(context);
return Scaffold(
body: ListView.builder(
itemCount: 1, // hard-coding this to 1
scrollDirection: Axis.vertical,
itemBuilder: (context, index) {
// here the index will always be zero,
// since above you specified itemCount = 1
summerNotifier.summerList[index]
}
)
);
}
I'd actually use the SummerNotifier service you have to hold on to the selected item reference and then in the Details page I get it from the service and populate the details of that item. Or in your case, the index of the selected item.
I believe that's your issue.

I have a list of items
List<String> items = [
"All",
"Jobs",
"Messages",
"Customers",
];
int current = 0;
And this list is directly responsible for my tab bar:
When i tap an item in the Tab bar i want to return a different container on each of them?
How do i go about this in flutter?
I tried returning an if statement just before the container but it seems i don't get the statement correctly.
this is the container i want to return if the item user select is All, and then put conditions in place for the rest items.
this is how i put the condition but it gives me this error
My return statement and code -
current = 0 ??

You can use Builder if want to display different type of widget based on the current index.
Builder(
builder: (context) {
switch (current) {
case 0:
return Container(
margin: const EdgeInsets.only(top: 30),
height: MediaQuery.of(context).size.height * 1,
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
const SizedBox(
height: 10,
),
Text(
items[current],
style: GoogleFonts.laila(
fontWeight: FontWeight.w500,
fontSize: 30,
color: Colors.deepPurple),
),
],
),
);
case 1:
return Text('Hello');
default:
return SizedBox.shrink();
}
},
);
Below approach will solve your problem. If you need further assistance, please feel free to comment.
int _currentIndex = 0;
var _containers = <Widget>[
AllContainer(),
JobsContainer(),
MessagesContainer(),
CustomerContainer(),
];
Widget _bottomTab() {
return BottomNavigationBar(
currentIndex: _currentIndex,
onTap: _onItemTapped, //
type: BottomNavigationBarType.fixed,
selectedLabelStyle: const TextStyle(color: Colors.blue),
selectedItemColor: WAPrimaryColor,
unselectedLabelStyle: const TextStyle(color: Colors.blue),
unselectedItemColor: Colors.grey,
items: const <BottomNavigationBarItem>[
BottomNavigationBarItem(label: 'All'),
BottomNavigationBarItem(
label: 'Jobs'),
BottomNavigationBarItem(
label: 'Messages'),
BottomNavigationBarItem( label: 'Customer'),
],
);
}
void _onItemTapped(int index) async {
print('bottom index::: $index');
setState(() {
_currentIndex = index;
});
}
#override
Widget build(BuildContext context) {
return SafeArea(
child: Scaffold(
bottomNavigationBar: _bottomTab(),
body: Center(child: _containers.elementAt(_currentIndex)),
),
);
}
You can use conditional if on widget level,
like
/// MAIN BODY
if (current == 0)
Container(
margin: const EdgeInsets.only(top: 30),
height: MediaQuery.of(context).size.height * 1,
...
),
if (current == 1) Text('hello')
Also can be use else if
if (current == 0)
Container(
margin: const EdgeInsets.only(top: 30),
height: MediaQuery.of(context).size.height * 1,
) //you shouldnt put coma
else if (current == 1) Text('hello')
],
),
);
But creating a separate method will be better instead of putting it here
Widget getWidget(int index) {
/// MAIN BODY
if (current == 0) // or switch case
return Container(
margin: const EdgeInsets.only(top: 30),
height: MediaQuery.of(context).size.height * 1,
); //you shouldnt put coma
else if (current == 1) return Text('hello');
return Text("default");
}
And call the method getWidget(current).
Also there are some widget like PageView, IndexedStack will help to organize the code structure
So, I'm pretty new on Flutter (just about a week) and dart but I hope this Question is not toooooo stupid:
I'm trying to create an App for an existing Website (a forum). I dont want to use the flutter WebView, because I want to create an comepletly new Interface (The Website is not optimized for mobile View, that's why I'm builing this App).
The (german) Forum:
https://www.porsche-914.com/forum
I want to fetch the single forum topics as well as the posts itself including username, title and date and then map the text to a custom widget to display it. The Widget Part is no problem, it's already done but I cant figure out how to fetch that data from the website and how to store it.
I don't know, hope you can help me...
Thanks a lot for the taken time.
How the mapping should work:
fetched[index].title, fetched[index].text
Center(
child: NeumorphismPost(
title: fetched[index].title,
titleColor: Theme.of(context).cardColor,
textColor: Theme.of(context).cardColor,
text: fetched[index].text,
width: 370,
onTap: () {
_popupPage(context,
title: fetched[index].title,
child: Padding(
padding: const EdgeInsets.all(15.0),
child: Text(
fetched[index].text,
style: TextStyle(
color: Theme.of(context).cardColor,
fontSize: 18),
),
),
);
},
),
),
This is my custom Widget:

this.borderRadius = 20,
this.titleColor = const Color(0xFF424242),

this.titleSize = 22,

From my point of view, you want to create a scraper. I checked the target website (https://www.porsche-914.com/forum), it can be scraped without any special technique (they don't have many Ajax calls (you may test by using Postman)). So it is a possible task. My suggestion flow is:
Load the raw HTML using any technique (http, dio, inappwebview ...)
Parse it using BeautifulSoup (https://pub.dev/packages/beautiful_soup_dart) (or any parser; it is just my favorite parser.)
Map it to your existing model.
Here is some example code. Hope it helps:
import 'package:http/http.dart' as http;
import 'package:beautiful_soup_dart/beautiful_soup.dart';
class TestParse {
excuteSample() async {
var url = Uri.parse('https://www.porsche-914.com/forum');
var response = await http.get(url);
BeautifulSoup bs = BeautifulSoup(response.body);
final allHeaderName = bs.findAll('td', attrs: {'class': 'oben'});
allHeaderName.forEach((element) {
print('the header: ${element.text}');
});
}
}
Here is the result:
The final result you need is a long story and long code. Hope this will give you a starting point.
UPDATE: I added the full demo code, using your requested code:
import 'package:beautiful_soup_dart/beautiful_soup.dart';
import 'package:flutter/material.dart';
import 'package:http/http.dart' as http;

This list I created is for sample, so it is just a list of Strings. You should create a complete Model.
I'm developing a job search app that scrapes data from Indeed using Python which is being sent back to my Flutter UI as JSON data. The JSON data is being received successfully, however, Im getting an error of Null check operator used on a null value. The error appears to be stemming from the _jobSearch widget.
The relevant error-causing widget was ListView lib/ui/home_page.dart:256
Exception caught by scheduler library

You are using the same quantity variable against each item. Changing the value on one of those will cause all items to update. What you need to do is to keep a Map of quantity selected against product id. That way whenever you increase or decrease the quantity, you update the quantity against that specific product id and the rest will remain unchanged.
EDIT: Here is how this will work
//Create a new map to save the product id and product selected quantity
var productQuantity = new Map<int, int>()
//When setting the values of the product, set the quantity from the map

you set the common quantity in all products so change it and set it inside the class.
Please Check the example
import 'package:flutter/material.dart';

#override
_QuantityUpdatePageState createState() => _QuantityUpdatePageState();
}
class _QuantityUpdatePageState extends State<QuantityUpdatePage> {
List<Product> productArray = [];
#override
void initState() {
super.initState();
WidgetsBinding.instance!.addPostFrameCallback((timeStamp) {
productArray.clear();
productArray.add(Product(1, "Product 1", 1));
productArray.add(Product(2, "Product 2", 1));
productArray.add(Product(3, "Product 3", 1));
productArray.add(Product(4, "Product 4", 1));
productArray.add(Product(5, "Product 5", 1));
setState(() {});
});

#Deepak if you don't understand Maps use list instead, with a value being updated for each index. Initialize a list of int types with some large values like 1000000, and update the value for each index. use ListView builder to fetch the data from the API for each index.
List<int> quantity = List.empty(growable: true);
OR
List<int> quantity = List.filled(10000, []);
For updating quantity:-
quantity[index] += 1;
For Grid view thing, refer this example from CodeGrepper:-
GridView.count(
// Create a grid with 2 columns. If you change the scrollDirection to
// horizontal, this produces 2 rows.
crossAxisCount: 2,
// Generate 100 widgets that display their index in the List.
children: List.generate(100, (index) {
return Center(
child: Text(
'Item $index',

I am a beginner in flutter.
I have created two ListView Builder where one ListView.builder is inside another builder as given below.
I have a list of categories which is inside one listview.builder and other are the list of products which also listview.builder Wrapped inside the above listview build>
So now i need to display the only items belonging to the 1st listview builder which means If I have a categories named soup (1st ListView.builder) Now i need to display only the products that belongs to soup categories from 2nd Listview.Builder but all the products are listed inside all the categories list. So, Please help me to find solution any help would be appriciated.Thank you in advance.
