How can I achieve such behavior in Flutter? any widget or plugins example?
See this gif
I tried carousels plugins and viewPagers widgets but couldn't make it work.
here is the sample code I started with.
CarouselSlider(
items: [
Container(child: Text("Complimentary"), width: double.infinity),
Container(child: Text("Complimentary"), width: double.infinity),
Container(child: Text("Complimentary"), width: double.infinity),
Container(child: Text("Complimentary"), width: double.infinity),
Container(child: Text("Complimentary"), width: double.infinity),
],
options: CarouselOptions(
height: 39 * resizeFactor,
autoPlay: false,
enlargeCenterPage: true,
autoPlayInterval: Duration(seconds: 10),
),
),
I made it work by using both Swiper and Row of arrows, with the following code:
Stack(
children: [
Container(
height: 39 * resizeFactor,
child: Swiper(
itemCount: 4,
itemBuilder: (context, index) => getIndexWidget(index), // -> Text widget.
viewportFraction: 0.4,
onIndexChanged: (value) {
setState(() => carouselIndex = value);
},
loop: false,
controller: swiperController,
),
),
Container(
padding: EdgeInsets.symmetric(horizontal: 30 * resizeFactor),
height: 39 * resizeFactor,
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceAround,
children: [
getIndicatorWidget(false), // back arrow icon.
getIndicatorWidget(true), // forward arrow icon.
],
),
),
],
),
Thank you for your contributions.

i created a carousel containing three different images. the problem is these images are not taking the full length of my current screen. i have tried setting the width in the image and even setting the aspect ratio and viewport in carousel options but the outcome is still the same. help would be very much appreciated. here is the code.
final List<Widget> _images = [
Stack(
children: [
Image.asset('assets/images/image 10.png'),
Padding(
padding: const EdgeInsets.only(left: 55.0, top: 230),
child: Text(
'Luxury \n Fashion \n &Accessories'.toUpperCase(),
style: TextStyle(
fontFamily: 'Bodoni',
fontSize: 40,
fontWeight: FontWeight.w500,
color: Colors.grey.shade700
),
),
),
Padding(
padding: const EdgeInsets.only(top: 400.0),
child: Center(
child:SvgPicture.asset('assets/iconImages/Button.svg'),
),
),
],
),
Image.asset('assets/images/leeloo.jpeg', width: double.infinity,),
Image.asset('assets/images/ayaka.jpeg', width: double.infinity,),
];
#override
Widget build(BuildContext context) {
return DefaultTabController(
length: 5,
child: Column(
children: [
Stack(
children: [
CarouselSlider.builder(
options: CarouselOptions(
viewportFraction: 1,
aspectRatio: 16/9,
height: MediaQuery.of(context).size.height*0.78,
autoPlay: false,
initialPage: 0,
enableInfiniteScroll: false,
enlargeCenterPage: true,
onPageChanged: (index, reason){
setState(() {
_activeIndex = index;
});
}
),
itemCount: _images.length,
itemBuilder: (BuildContext context, int index, int realIndex) {
return GestureDetector(
onTap: (){
Navigator.of(context).pushNamedAndRemoveUntil(BlackScreen.routeName, (route) => false);
},
child: Align(
alignment: Alignment.bottomCenter,
child:Container(
child: _images[index]
),
),
);
},
),
Set fit to your image like this:
Image.asset('assets/images/leeloo.jpeg', width: double.infinity,fit: BoxFit.cover),
Please try this
FittedBox(
child: Image.asset('foo.png'),
fit: BoxFit.fill,
)
I have used CarouselSlider for my other projects but the first time I could not find the reason why it gives that warning. Here is a simplified code part. I did not use any flexible or expanded widget in Stack or its parent. Mostly answers about that but there has to be a point that I am missing. Here is the link of dependency. Do you have any suggestions?
return Scaffold(
body: Column(
children: [
SizedBox(
height: (MediaQuery.of(context).size.height -
70.h -
MediaQuery.of(context).viewPadding.top) *
0.35,
child: slider()),
])
);
Stack slider() {
return Stack(
children: [
CarouselSlider(
options: CarouselOptions(
autoPlayInterval: const Duration(seconds: 2),
autoPlay: true,
// aspectRatio: 2.3,
height: (MediaQuery.of(context).size.height -
70.h -
MediaQuery.of(context).viewPadding.top) *
0.35,
viewportFraction: 0.8,
enlargeCenterPage: true,
enlargeStrategy: CenterPageEnlargeStrategy.scale,
onPageChanged: (index, reason) {
setState(() {
_current = index;
});
}),
items: images
.map(
(item) => Center(child: item),
)
.toList(),
),
Positioned(
child: Column(
children: [
SizedBox(
height: (MediaQuery.of(context).size.height -
70.h -
MediaQuery.of(context).viewPadding.top) *
0.3),
Row(
mainAxisAlignment: MainAxisAlignment.center,
children: images.asMap().entries.map((entry) {
return Container(
width: 8.w,
height: 8.h,
margin:
EdgeInsets.symmetric(vertical: 8.w, horizontal: 4.h),
decoration: BoxDecoration(
shape: BoxShape.circle,
color: ColorSelect.color
.withOpacity(_current == entry.key ? 1 : 0.4)),
);
}).toList(),
),
],
),
)
],
);
}
how to add these images in carousal in flutter
Use this carousel_slider 4.0.0 package from pubdev.
Installation
Add carousel_slider: ^4.0.0 to your pubspec.yaml dependencies. And import it:
import 'package:carousel_slider/carousel_slider.dart';
How to use
Simply create a CarouselSlider widget, and pass the required params:
CarouselSlider(
options: CarouselOptions(height: 400.0),
items: [1,2,3,4,5].map((i) {
return Builder(
builder: (BuildContext context) {
return Container(
width: MediaQuery.of(context).size.width,
margin: EdgeInsets.symmetric(horizontal: 5.0),
decoration: BoxDecoration(
color: Colors.amber
),
child: Text('text $i', style: TextStyle(fontSize: 16.0),)
);
},
);
}).toList(),
)
https://pub.dev/packages/smooth_page_indicator you can use this for dot animation along with https://pub.dev/packages/carousel_slider here is a little example please adjust size accordingly
class Carosel extends StatelessWidget {
List<listScreen> introduction = [
listScreen(image: 'assets/Reading_Plans.png'),
listScreen(image: 'assets/Reading_Plans.png'),
listScreen(image: 'assets/Reading_Plans.png'),
listScreen(image: 'assets/Reading_Plans.png'),
];
set index(value) => _index.value = value;
get index => _index.value;
final _index = 0.obs;
final CarouselController _controller = CarouselController();
#override
Widget build(BuildContext context) {
return Scaffold(
body: SafeArea(
child: Container(
width: MediaQuery.of(context).size.width / 1.5,
child: Column(
children: [
Container(
height: MediaQuery.of(context).size.height / 2,
child: CarouselSlider(
carouselController: _controller,
options: CarouselOptions(
enableInfiniteScroll: false,
viewportFraction: 1,
height: MediaQuery.of(context).size.height / 3,
aspectRatio: 1.0,
onPageChanged: (ind, reason) {
index = ind;
}),
items: introduction
.map((listScreen item) => Column(
children: [
SizedBox(
height: kToolbarHeight / 2,
),
Container(
child: Image(
image: AssetImage(item.image),
),
),
SizedBox(
height: 20,
),
// Spacer(),
],
))
.toList(),
),
),
Spacer(),
Padding(
padding: const EdgeInsets.symmetric(
horizontal: 35.0,
vertical: 15,
),
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
Obx(() {
return index != 3
? Container(
width: 90,
child: AnimatedSmoothIndicator(
activeIndex: index,
count: 4,
effect: ExpandingDotsEffect(
dotHeight: 13,
dotWidth: 13,
activeDotColor: Color(0xff5C5C78),
),
),
: Container();
}),
],
),
),
Spacer(),
],
),
),
),
);
}
}
The other answers are correct and fully functional. You can use
carousel_slider: ^4.0.0
or simply follow the following link to get a complete understanding of code.

I am trying to achieve something like this in the video https://youtu.be/tpfP7wlHCxw , when the slider image will change the below text will also change like fat in the video example, and also one container box on the front image only
I tried the carousel_slider and use the stack for box frame that is in the video but frame size and image sizes not adjustable
and the important thing is how can I change the below text on change image and slider should not rotate it will stop if the last image comes
here is my code
import 'package:carousel_slider/carousel_slider.dart';
import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';
import 'package:trainer_app/color.dart';
class FatGet extends StatefulWidget {
#override

With onPageChange, you can take the value of a variable and return it from a function you send. I think it will work.
Define each text as companent.
Check the index of images with a variable
Write the function that returns value according to the parameter sent.
Call the function and give the control variable
for slider should not rotate.. see comment 1 in the code
for change the below text on change.. see comment 2
CarouselSlider(
items: items,
options: CarouselOptions(
height: 400,
aspectRatio: 16/9,
viewportFraction: 0.8,
initialPage: 0,
enableInfiniteScroll: false, // (1) Set to false
reverse: false,
autoPlay: true,
autoPlayInterval: Duration(seconds: 3),
autoPlayAnimationDuration: Duration(milliseconds: 800),
autoPlayCurve: Curves.fastOutSlowIn,
enlargeCenterPage: true,
onPageChanged: changeActiveImageText(), // (2) Set up your function here
scrollDirection: Axis.horizontal,
)
)
Function will look something like this
changeActiveImageText(){
// your method of changing the text
setState((){})
}
I have a carousel, two iconButtons in a Positioned Layout, gridView and 2 other positioned layouts All Inside A Stack Layout.
The onPressed() functions on the iconButtons specifically or on any of the elements general do not get triggered. I figured out that the issue is because of the Parent Stack Layout because when place them outside of it the onPressed works.
I need the Stack Layout for the design so im wondering if there is an alternative for it.
Here's an example of the code:
child: Stack(
children: <Widget>[
Container(
child: Column(
children: <Widget>[
carouselSlider = CarouselSlider(
height: 270.0,
initialPage: 0,
viewportFraction: 1.0,
aspectRatio: 1.0,
enlargeCenterPage: false,
autoPlay: true,
reverse: false,
enableInfiniteScroll: true,
autoPlayInterval: Duration(seconds: 2),
autoPlayAnimationDuration:
Duration(milliseconds: 2000),
pauseAutoPlayOnTouch: Duration(seconds: 10),
scrollDirection: Axis.horizontal,
onPageChanged: (index) {
setState(() {
current = index;
});
},
items: carouselImages.map((i) {
return Builder(
builder: (BuildContext context) {
return Container(
child: GestureDetector(
// behavior:
// HitTestBehavior.translucent,
child: Image.asset(
i,
fit: BoxFit.cover,
),
onTap: () {
// Navigator.push<Widget>(
// context,
// MaterialPageRoute(
// builder: (context) => ImageScreen(i),
// ),
// );
}));
},
);
}).toList(),
),
SizedBox(
height: 20,
),
Row(
mainAxisAlignment: MainAxisAlignment.center,
children:
map<Widget>(carouselImages, (index, url) {
return Container(
width: 10.0,
height: 10.0,
margin: EdgeInsets.symmetric(
vertical: 10.0, horizontal: 2.0),
decoration: BoxDecoration(
shape: BoxShape.circle,
color: current == index
? Color.fromRGBO(221, 40, 42, 0.7)
: Colors.white,
),
);
}),
),
],
),
),
Positioned(
right: 5,
top: 10,
child: IconButton(
icon: Icon(Icons.menu),
color: Color.fromRGBO(221, 40, 42, 0.7),
iconSize: 20.0,
onPressed: () {
print('Clicked');
scaffolddKey.currentState.openDrawer();
},
),
),
The solution is to wrap all of your widgets that are not supposed to receive tap events in IgnorePointer widget.
If your CarouselSlider is not supposed to receive tap events then wrap it and all other widgets that are not supposed to receive tap events in IgnorePointer widget.
