Flutter carousel slider place text under image - flutter

I am trying to place text under a image in my carousel slider but now the text appears on the image, not under.
It looks like this:
But I want it to look like this:
Here is my code:
final CarouselSlider autoPlayDemo = CarouselSlider(
viewportFraction: 0.9,
aspectRatio: 2.0,
autoPlay: false,
enlargeCenterPage: true,
items: imgList.map(
(child) {
return Container(
margin: EdgeInsets.all(10.0),
child: ClipRRect(
borderRadius: BorderRadius.all(Radius.circular(5.0)),
child: Stack(children: <Widget>[
Image.asset(
child,
fit: BoxFit.cover,
width: 1000.0,
),
Padding(
padding: EdgeInsets.symmetric(vertical: 10.0, horizontal: 20.0),
child: Text(
'Text',
style: TextStyle(
color: Colors.white,
fontSize: 20.0,
fontWeight: FontWeight.bold,
),
))
])),
);
},
).toList(),
);
What can I do to place the text under the image insted of on the image?
Stack(children: <Widget>[
Container(
width: MediaQuery.of(context).size.width,
height: 600,
decoration: BoxDecoration(
color: Color.fromRGBO(217,225,216,1),
),
padding: EdgeInsets.symmetric(vertical: 20.0, horizontal: 20.0),
child: Text(
'News',
style: TextStyle(
color: Colors.black,
fontSize: 20.0,
fontWeight: FontWeight.bold,
),
),
),
Padding(
padding: EdgeInsets.symmetric(vertical: 50.0),
child: Column(children: [
autoPlayDemo,
])),
]),

Wrapping them with a Stack widget is wrong. Stack is a widget that displays its children over each other. Instead, wrap them in a Column widget that displays its children in a horizontal manner under each other.
Also wrap the image with the ClipRRect to achieve your goal.
final CarouselSlider autoPlayDemo = CarouselSlider(
viewportFraction: 0.9,
aspectRatio: 2.0,
autoPlay: false,
enlargeCenterPage: true,
items: imgList.map(
(child) {
return Container(
margin: EdgeInsets.all(10.0),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
ClipRRect(
borderRadius: BorderRadius.all(Radius.circular(5.0)),
child: Image.asset(
child,
fit: BoxFit.cover,
width: 1000.0,
),
),
Expanded(
child: Padding(
padding:
EdgeInsets.symmetric(vertical: 10.0, horizontal: 20.0),
child: Text(
'Text',
style: TextStyle(
color: Colors.white,
fontSize: 20.0,
fontWeight: FontWeight.bold,
),
),
),
),
],
),
);
},
).toList(),
);

This is complete working code with Image on top with text and dots. For this you need to use these two libraries:- " carousel_slider: ^4.1.1 ", "smooth_page_indicator: ^1.0.0+2", update them to the latest.
class MyItem {
String itemName;
String path;
MyItem(this.itemName, this.path);
}
class craouselImage extends StatefulWidget {
#override
_craouselImage createState() => _craouselImage();
}
class _craouselImage extends State<craouselImage> {
int activeIndex = 0;
List<MyItem> items = [
MyItem("item 1", 'assets/images/appiconlogo.png'),
MyItem("item 2", 'assets/images/Mockup4.png'),
];
#override
Widget build(BuildContext context) {
return Container(
child: Column(
children: [
CarouselSlider.builder(
itemCount: items.length,
options: CarouselOptions(
height: 400,
viewportFraction: 1,
autoPlay: true,
enlargeCenterPage: true,
enlargeStrategy: CenterPageEnlargeStrategy.height,
autoPlayInterval: const Duration(seconds: 1),
onPageChanged: (index, reason) {
setState(() {
activeIndex = index;
});
},
),
itemBuilder: (context, index, realIndex) {
final imgList = items[index];
return Column(
crossAxisAlignment: CrossAxisAlignment.start,
mainAxisSize: MainAxisSize.min,
children: [
Expanded(child: buildImage(imgList.path, index)),
const SizedBox(
height: 15,
),
buildText(imgList.itemName, index),
],
);
},
),
const SizedBox(
height: 22,
),
buildIndicator(),
const SizedBox(
height: 22,
),
//buildText(itemName, index),
// buildText(),
],
),
);
}
Widget buildImage(String imgList, int index) => Container(
margin: const EdgeInsets.symmetric(horizontal: 12),
color: Colors.transparent,
child: Align(
alignment: Alignment.center,
child: Image.asset(
imgList,
fit: BoxFit.cover,
),
),
);
buildIndicator() => AnimatedSmoothIndicator(
activeIndex: activeIndex,
count: items.length,
effect: const JumpingDotEffect(
dotColor: Colors.black,
dotHeight: 15,
dotWidth: 15,
activeDotColor: mRed),
);
buildText(String itemName, int index) => Align(

How to set number of elements to show in a CarouselSlider per page, using carousel_slider in flutter

I'm creating a vertical carousel slider using carousel_slider but there's a huge empty space between elements and I can't display the previous element on the screen. What is the best way to remove the empty space and also show the previous element.
My screen is set as follows
Column(
children: [
Container(
margin: const EdgeInsets.fromLTRB(16, 16, 16, 16),
child: TextField(
controller: controller,
),
),
//Carousel built here
Expanded(
child: CarouselSlider.builder(
itemCount: cars.length,
itemBuilder: (context, index, pageViewIndex) => CarTile(
car: cars[index],
onpress: () => Navigator.push(
context,
MaterialPageRoute(
builder: (context) =>
CarDetailsScreen(car: cars[index]))),
),
options: CarouselOptions(
scrollDirection: Axis.vertical,
enlargeCenterPage: true,
),
),
),
],
);
CarTile code is as follows:
class CarTile extends StatelessWidget {
final Car car;
final VoidCallback onpress;
const CarTile({super.key, required this.onpress, required this.car});
#override
Widget build(BuildContext context) {
Size size = MediaQuery.of(context).size;
return GestureDetector(
onTap: onpress,
child: Padding(
padding: const EdgeInsets.fromLTRB(8, 0, 8, 0),
child: Column(
children: [
Image.network(
height: 150,
width: size.width,
fit: BoxFit.fitWidth,
car.image,
),
const SizedBox(
height: 5,
),
Padding(
padding: const EdgeInsets.only(top: 8.0, bottom: 8.0),
child: Row(
children: [
Container(
decoration: BoxDecoration(
color: Colors.grey[200],
borderRadius: BorderRadius.circular(5)),
child: Text(
car.features[0],
style: const TextStyle(fontWeight: FontWeight.w500),
),
),
const SizedBox(
width: 5,
),
Container(
decoration: BoxDecoration(
color: Colors.grey[200],
borderRadius: BorderRadius.circular(5)),
child: Text(
car.features[1],
style: const TextStyle(fontWeight: FontWeight.w500),
),
),
],
),
),
Row(
children: [
Text(
'${car.brand} ${car.model}',
style: const TextStyle(fontWeight: FontWeight.w900),
),
const Spacer(),
Text(
'Tsh. ${NumberFormat.decimalPattern().format(car.price)} / hr',
style: const TextStyle(fontWeight: FontWeight.w900),
),
],
),
Align(alignment: Alignment.centerLeft, child: Text('${car.year}'))
],
),
),
);
}
}
And this is my current results

Why I'm not able to get the updated variable even using setstate inside the stateful widget. As I want to update my Container on new TabBar option

Basically I want to change content on selecting the TabBar options. Here's my code. Also I'm new to flutter. I've also created a _incrementCounter() and getter setter methods. By using _incrementCounter() I'm returning an integer in order to update the PAgeView of my screen which is implemented inside a List called tabsCat. But on calling the _incrementCounter() method on line 264 it does not give the updated value please guide.

Solve the error by calling the _incrementcounter method onto OnTap section. Here's my code changes:
Edited incrementcounter method and declare new method setNewCount,
void setNewCount(int newCount) {
count = newCount;
}
void _incrementCounter() {
setState(() {
count = getCount;
});
}
2nd change :
onTap: (index){
setNewCount(index);
_incrementCounter();
},
3rd change:
Container(
height: 218.4,
margin: EdgeInsets.only(top: 16),
child: tabsCat[count],
),
Try
onTap: (index){
setCount(index);
//print(getCount);
},
instead of
onTap: (index){
setCount = index;
//print(getCount);
},

Does anyone have a way to fixed this.
I need to keep the text as it gets, so I need a way to expand the widget when it need to expand
GridView must have a childAspectRatio property, try to play around with that and see if you have the wanted result
try wrapping your stack with Expanded with flex:1

Update when tap TabBar
TabBar(onTap: (_) => setState((){}));

Fit Container Widget Height to Parent Row Height

I have a web application with the following layout:
I am trying to create a flutter application with a similar layout and this is what I have so far:

The above code is ready to be pasted into the main.dart file and preview on a the virtual device (preferably tablet).
So far I have tried the solutions I found on these posts to no avail:
- Make container widget fill parent vertically
- Flutter Container height same as parent height
- Flutter expand Container to fill remaining space of Row
- The equivalent of wrap_content and match_parent in flutter?
Since the Row that contains the section Container also has a ListView being generated with the FutureBuilder, the height of the Row automatically expands to fit the ListView. I also want the section Container to expand to the same height as the how the Row widget is expanding; i.e., The bottom border of the section Container that says FRONT, should be aligned with the bottom border of the Hight Voltage system and the right border of the FRONT section Container, should go all the way to the top.
I already spent 3 days without a resolution.
Edit
I have tried the suggestion on the answer provided by #MaadhavSharma but I get the following exception:
════════ Exception Caught By rendering library ════════════════════════════
The following assertion was thrown during performLayout():
BoxConstraints forces an infinite height.
I changed a little the structure to make it work, here is the entire build() method:

Basically I changed the ListView of the second element of the Row for a Column, since it already was inside a ListView and that was making it have double scroll and the heights weren't expanding the height of the row properly, and also I wrapped the Row inside an IntrinsicHeight and put crossAxisAlignment: CrossAxisAlignment.stretch to the Row so the content will fit the height of the Row.
The use of IntrinsicHeight is expensive, but I don't see another solution for the way you structured the widgets. I recommend you to try to optimize all the structure so you could find a better and optimal solution.
If you want to stretch the Container to match its parent, use double.infinity for the height and width properties
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(title: Text('Container as a layout')),
body: Container(
height: double.infinity,
width: double.infinity,
color: Colors.yellowAccent,
child: Text("Hi"),
),
);
}
The trick is to use constraints: BoxConstraints.expand() in some of your containers that you want to expand to fill the row height.
Try something like this:
Scaffold(
appBar: AppBar(
title: Text("Title"),
),
body: Container(
padding: EdgeInsets.all(16.0),
child: Column(
children: <Widget>[
Expanded(
flex: 2,
child: Container(
padding: EdgeInsets.fromLTRB(0, 0, 0, 0),
color: Colors.yellow,
child: Row(
children: <Widget>[
Expanded(
flex: 1,
child: Container(
constraints: BoxConstraints.expand(),
color: Colors.blue,
child: Text("box 1")),
),
Expanded(
flex: 2,
child: Container(
constraints: BoxConstraints.expand(),
color: Colors.red,
child: Column(
children: <Widget>[
Expanded(
flex: 2,
child: Container(
padding:
EdgeInsets.fromLTRB(0, 0, 0, 0),
color: Colors.yellow,
child: Row(
children: <Widget>[
Expanded(
flex: 1,
child: Container(
constraints:
BoxConstraints.expand(),
color: Colors.lightGreen,
child: Text("box 2")),
),
Expanded(
flex: 2,
child: Container(
constraints:
BoxConstraints.expand(),
color: Colors.lightBlue,
child: Text("box 3")),
),
],
),
),
),
Expanded(
flex: 1,
child: Container(
padding:
EdgeInsets.fromLTRB(0, 0, 0, 0),
color: Colors.yellow,
child: Row(
children: <Widget>[
Expanded(
flex: 1,
child: Container(
constraints:
BoxConstraints.expand(),
color: Colors.purple,
child: Text("box 4")),
),
Expanded(
flex: 2,
child: Container(
constraints:
BoxConstraints.expand(),
color: Colors.orange,
child: Text("")),
),
],
),
),
),
],
)),
),
],
),
),
),
Expanded(
flex: 1,
child: Container(
padding: EdgeInsets.fromLTRB(0, 0, 0, 0),
color: Colors.yellow,
child: Row(
children: <Widget>[
Expanded(
flex: 1,
child: Container(
constraints: BoxConstraints.expand(),

I think you will need to use some fixed heights since you are using ListView and FutureBuiulders. If you can get rid of FutureBuilders, you can probably achieve dynamic heights. Notice the hright of 320 on the parent row and height of 160 on child rows.
But have a look at this:
import 'package:flutter/material.dart';
void main() => runApp(MyApp());
class MyApp extends StatelessWidget {
#override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Assemblers Tasks',
debugShowCheckedModeBanner: false,
theme: ThemeData(
primarySwatch: Colors.deepOrange,
),
home: MyHomePage(title: 'Assembly Tasks'),
);
}
}
class MyHomePage extends StatefulWidget {
MyHomePage({Key key, this.title}) : super(key: key);
final String title;
#override
_MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
String dropdownValue;
List<Map<String, dynamic>> buildItems = [];
getBuilds() {
List<Map<String, dynamic>> items = [];
items.add({"id": 10, "vehicleModel": "A10", "vehicleNumber": "TEST-00010"});
setState(() {
buildItems = items;
});
}
List<Map<String, dynamic>> buildSections = [];
getSections() {
List<Map<String, dynamic>> items = [];
items.add({
"id": 5,
"section": "Front",
});
items.add({
"id": 15,
"section": "Rear",
});
setState(() {
buildSections = items;
});
}
Future<List<Map<String, dynamic>>> getSystems(String buildSectionId) async {
List<Map<String, dynamic>> items = [];
if (int.parse(buildSectionId) == 5) {
items.add({
"id": 4,
"system": "Hydraulics",
});
items.add({
"id": 20,
"system": "High Voltage",
});
}
return items;
}

super.initState();
