ListView Implementation - flutter

Please help me or give me an idea on how to implement the above image. I'm planning to use ListView. Below is my sample code but this is on horizontal scroll.
Widget build(BuildContext context) {
return Container(
height: 210,
color: Theme.of(context).primaryColor,
padding: EdgeInsets.symmetric(vertical: 10),
child: ListView.builder(
itemCount: _foodsList.featuredList.length,
itemBuilder: (context, index) {
double _marginLeft = 0;
(index == 0) ? _marginLeft = 20 : _marginLeft = 0;
return FoodsCarouselItemWidget(
heroTag: 'home_food_carousel',
marginLeft: _marginLeft,
food: _foodsList.featuredList.elementAt(index),
);
},
scrollDirection: Axis.horizontal,
));
}
}

You need to build your layout in itemBuilder property of ListView. If you want to place the text on the image the best layout widget is Stack.
See the following in order to get the layout system of flutter: https://flutter.io/tutorials/layout/
and for all the available layout widgets see: https://flutter.io/widgets/layout/
and Stack: https://docs.flutter.io/flutter/widgets/Stack-class.html
Something like this:new Stack(
children: <Widget>[
new Positioned.fill(
child: new FadeInImage(
placeholder: new AssetImage('placeholder.png'),
image: new CachedNetworkImageProvider(photos[int].url),
fit: BoxFit.contain,
alignment: Alignment.center,
fadeInDuration: new Duration(milliseconds: 200),
fadeInCurve: Curves.linear,
),
),
new Positioned(
top: 10.0,
left: 10.0,
child: new Container(
child: new Text(photos[int].title)
),
),
],
)

I have tried my best to achieve the same, but due to time issues, you might find a little different.

i tried to make the logo in another Row() but i dont know how its works
You are using listView inside listView instead of column main issue.
also you used some widgets incorrectly which will not correct for response mobile app. try this i updated your code.
for Ads view only on top you need to place out side the ListView so it will display only once.
| Scaffold |
| - Column[.. |
| AdsView |
| Expanded |
| ListView ..] |
try this Code:
Scaffold(
body: Column(
children: [
Container(
margin: const EdgeInsets.only(left: 70, right: 60),
height: 54.0,
width: 224.0,
child: Container(
decoration: BoxDecoration(
border:
Border.all(color: const Color(0xffF4AC47), width: 5),
color: const Color(0xff42A9D2),
borderRadius: const BorderRadius.only(
bottomLeft: Radius.circular(40),
bottomRight: Radius.circular(40))),
child: const Center(
child: Text(
"MyAds",
style: TextStyle(
fontSize: 25,
color: Color(0xff072A52),
fontFamily: 'Cairo'),
textAlign: TextAlign.center,
),
//end logo
)),
),
const SizedBox(
height: 35,
),
Expanded(
child: ListView.builder(
itemCount: list.length,
itemBuilder: ((cts, i) {
return Column(
children: [
Container(
margin: const EdgeInsets.symmetric(horizontal: 10),
height: 180.0,
child: Container(
decoration: BoxDecoration(
border: Border.all(
color: const Color(0xff42A9D2), width: 5),
borderRadius: BorderRadius.circular(8)),
child: Row(
children: [
const Expanded(
flex: 3,
child: Image(
image: AssetImage("assets/book.jpg"),
),
),
Expanded(
flex: 6,
child: Column(
crossAxisAlignment: CrossAxisAlignment.end,
mainAxisAlignment: MainAxisAlignment.center,
children: [
const Text(
// "${list[i]["book_name"]}",
"book_name",
style: TextStyle(
fontSize: 20, color: Colors.black87),
),
const SizedBox(height: 12),
Row(
mainAxisAlignment: MainAxisAlignment.end,
children: [
Text("${list[i]["collage"]}"),
const Icon(Icons.perm_identity_rounded)
],
),
const SizedBox(height: 12),
Row(
mainAxisAlignment: MainAxisAlignment.end,
children: [
Text("${list[i]["loc"]}"),
const Icon(Icons.store)
],
),
],
),
)
],
),
),
),
const SizedBox(height: 16),
],
);
}),
),
),
],
),
)
The problem is because you are putting MyAds in ListView.builder. You need to remove the MyAds TextView from ListView.builder.
The correct way should be
-Column
-Your AdsView text
-ListView.builder

How can i make a horizontal scrolling list View builder with dynamic height?

//ListView Builder

itemBuilder: (context, index) => InkWell(
onTap: () {
Get.toNamed(RoutesName.allCoursesPageDetails);
allCoursesController.getAllCourseDetails(
controller.homeData!.bestSaleWebinars[index].slug);
},
child: newCoursesBuilder(

You can wrap the List view builder in an IntrinsicHeight widget, so the height of the ListView builder will be dynamic
You can try using SingleChildScrollView
SingleChildScrollView(
scrollDirection: Axis.horizontal,
child: Row(
children: List.generate(
44,
(index) => Padding(
padding: EdgeInsets.only(right: 10),
child: Container(
...
),
),
)),
)

Flutter: How to implement State Management onPressed

I have no idea how to change the state of my grid view when a button is clicked can someone help me with this?
So, I have this textButton that should change the state of my grid view when clicked but I have no idea how to implement it. Below is my code.
From the image attached, when water, food, school etc are clicked the gridview should only provide specific organizations..
Widget build(BuildContext context) {
return Container(
padding: const EdgeInsets.all(20.0),
child: ListView(
children: <Widget>[
ClipRRect(
borderRadius: BorderRadius.circular(20),
child: Container(

//here is the textButton

GridView.count(

mainAxisSpacing: 10,
children: _listItem
.map((item) => Card(

)),
))
.toList(),
)
],
),
);
}
}
Thanks very much.
The simplest things to do is to Filter your items based on selection by using the .where of Iterable https://api.flutter.dev/flutter/dart-core/Iterable/where.html
Basically when you push your Text button you store the type in a variable (you need a StatefulWidget for that)
then you can use where to filter your _listItem
GridView.count(
shrinkWrap: true,
physics: NeverScrollableScrollPhysics(),
crossAxisCount: 2,
crossAxisSpacing: 10,
mainAxisSpacing: 10,
children: _listItem
.where((element) {
//if your element is included return true else false
return true;
})
.map((item) => Card(
color: Colors.transparent,
elevation: 0,
child: GestureDetector(
onTap: () => Navigator.pushNamed(context, item.route),
child: Container(
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(20),
image: DecorationImage(
image: AssetImage(item.image),
fit: BoxFit.cover)),
)),
))
.toList(),
)
You can check a sample here for the behavior on the button:

As you have mentioned SingleChildScrollView should work, but your problem is that you don't have enough items to be scrolled according to your screenshot.
So please use enough items and try again.
And in your _buildPopularItem() widget, decrease the container width, that's why it says pixel overflow.
This overflow is made from _buildPopularTitle() while you set fixed height from _buildPopularSection having height: 200,
if you look closely, inside _buildPopularItem
There is a Container with height: 200, and it is taking full height, so for rest of children SizedBox h:5 and Container Text aren't having any spaces here, and creating overflow.
Solutions
increase the height of _buildPopularSection
reduce the container height inside _buildPopularItem
wrap with FittedBox(child: _buildPopularItem());
From the screenshot I can see that your container is smaller by 21 pixels in height. Please increase it.
_buildPopularSection() {
return Container(
height: 230,
padding: EdgeInsets.only(left: 20),
width: MediaQuery.of(context).size.width,
child: Container(
child: ListView.builder(
itemCount: 6,
physics: NeverScrollableScrollPhysics(),
scrollDirection: Axis.horizontal,
shrinkWrap: true,
itemBuilder: (context, position) {
return _buildPopularItem();
},
),
),
);
}
_buildPopularItem() {
return Column(
children: [
Container(
height: 225,
width: 150,
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(20),
color: Colors.red,
),
margin: EdgeInsets.only(right: 16),
child: Image.network(

Replace the above code and it should work...
