Can I add a CarouselSlider to a PageView.builder, no auto scroll - flutter

I have a Futurebuilder that works with a ListView.builder that displays on the screen but I wanted to add the carousel_slider package but nothing happens, the Carouselslider is set to auto scroll . I can still so it manually like a list view.
My Code:
There are just 2 elements from the Future on the screen, image and a title image.
import 'package:carousel_slider/carousel_slider.dart';
import 'package:flutter/material.dart';
import '../../future_carousel.dart';
class CarouselInformation extends StatelessWidget {
CarouselInformation({Key? key}) : super(key: key);
var datasource = const FutureInformation();
getSliderDetailsEvents() async {
List futureEvents = await datasource.getSliderDetails();
return futureEvents;
}
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(title: const Text('Sliders')),
body: SingleChildScrollView(
child: Column(
children: [
FutureBuilder(
future: getSliderDetailsEvents(),
builder: (BuildContext context, AsyncSnapshot snapshot) {
if (snapshot.data == null) {
return const CircularProgressIndicator();
} else {
return Column(
children: [
const Text('Block 1'),
CarouselSlider(
options: CarouselOptions(
aspectRatio: 1.5,
viewportFraction: 1.0,
enlargeCenterPage: true,
enlargeStrategy: CenterPageEnlargeStrategy.height,
enableInfiniteScroll: false,
initialPage: 2,
autoPlay: true,
),
items: [
SizedBox(
height: 260,
width: 375,
child: Expanded(
child: PageView.builder(
scrollDirection: Axis.horizontal,
itemCount: snapshot.data.length,
itemBuilder:
(BuildContext context, int index) {
return Container(
margin: const EdgeInsets.all(5.0),
child: ClipRRect(
borderRadius: const BorderRadius.all(
Radius.circular(5.0)),
child: Stack(
children: [
Image.network(
snapshot.data[index].image,
fit: BoxFit.cover),
Positioned(
bottom: 0.0,
left: 0.0,
right: 0.0,
child: Container(
decoration:
const BoxDecoration(
gradient: LinearGradient(
colors: [
Color.fromARGB(
200, 0, 0, 0),
Color.fromARGB(
0, 0, 0, 0)
],
begin: Alignment
.bottomCenter,
end: Alignment.topCenter,
),
),
padding: const EdgeInsets
.symmetric(
vertical: 10.0,
horizontal: 20.0),
child: Text(
snapshot.data[index].title,
style: const TextStyle(
color: Colors.white,
fontSize: 20.0,
fontWeight:
FontWeight.bold,
),
),
),
),
],
),
),
);
},
),
),
),
]),
],
);
}
}),
],
),
),
);
}
}
Result of the code above:
I want to achieve the same effect as the bottom Widget as on this clip but the images on that clip which is working are hardcoded not from a Future.

You can use GridView.builder() to do this
List<Widget> buttonList = [Button1(),Button2(),Button3(),Button4(),Button5(),Button6(),Button7(),Button8(),Button9()];
// inside body
body: Column(
children: [
CarouselSlider(
options: CarouselOptions(
autoPlay: true,
aspectRatio: 2.0,
enlargeCenterPage: true,
),
items: imageSliders,
),
GridView.builder(
gridDelegate: const SliverGridDelegateWithFixedCrossAxisCount(
crossAxisCount: 3, // number of widgets in a row
crossAxisSpacing: 10.0,
mainAxisSpacing: 10.0,
childAspectRatio: (1.0 / 1.2),
),
itemBuilder: (BuildContext context, int index) {
return buttonList[index];
},
itemCount: buttonList.length,
),
],)

How to scroll with NestedScrollView to use stack Circle Avatar over SliverAppBar?

I am dealing with a Flutter project recently and I have such a problem.
See photo 1: here's my code: the photo and text should be between the TabBar widget and the red background like in design (blue).
Here you can see my actual code:
class Main
body: NestedScrollView(
headerSliverBuilder: (BuildContext context, bool innerBoxIsScrolled) {
return <Widget>[
PortfolioSliverAppBar(_pages[_tabController.index].item1),
SliverPersistentHeader(
delegate: SliverPersistentHeaderDelegateImpl(
tabBar: TabBar(
padding: EdgeInsets.only(top: 15.0),
labelColor: Colors.black,
indicatorColor: Colors.black,
indicator: BoxDecoration(
borderRadius: BorderRadius.all(Radius.circular(18)),
color: Colors.blue),
controller: _tabController,
tabs: _pages
.map<Tab>((Tuple3 page) => Tab(text: page.item1))
.toList(),
),
),
),
];
},
body: Container(
margin: EdgeInsets.only(top: 20.0),
child: TabBarView(
controller: _tabController,
children: _pages.map<Widget>((Tuple3 page) => page.item2).toList(),
),
),
class Silver
class SliverPersistentHeaderDelegateImpl extends SliverPersistentHeaderDelegate {
final TabBar tabBar;
final Color color;
const SliverPersistentHeaderDelegateImpl({
Color color = Colors.transparent,
#required this.tabBar,
}) : this.color = color;
#override
Widget build(BuildContext context, double shrinkOffset, bool overlapsContent) {
return Container(
color: color,
child: tabBar,
);
}

How to create multiple horizontal `GridView` in the same screen using flutter

Is there's a way to create a lists of GridViews as the below image in one screen...
I have a some Screen as the below one:
class _MyHomePageState extends State<MyHomePage> with TickerProviderStateMixin {
var _showOnlyFavorites = false;
AnimationController animationController;
bool multiple = true;
#override
void initState() {
animationController = AnimationController(
duration: const Duration(milliseconds: 2000), vsync: this);
super.initState();
}
Future<bool> getData() async {
await Future<dynamic>.delayed(const Duration(milliseconds: 0));
return true;
}
#override
void dispose() {
animationController.dispose();
super.dispose();
}
#override
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: AppTheme.white,
body: FutureBuilder<bool>(
future: getData(),
builder: (BuildContext context, AsyncSnapshot<bool> snapshot) {
if (!snapshot.hasData) {
return const SizedBox();
} else {
return Padding(
padding: EdgeInsets.only(top: MediaQuery.of(context).padding.top),
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
appBar(),
Expanded(
child: FutureBuilder<bool>(
future: getData(),
builder:
(BuildContext context, AsyncSnapshot<bool> snapshot) {
if (!snapshot.hasData) {
return const SizedBox();
} else {
return PropertiesGrid(_showOnlyFavorites);
}
},
),
),
],
),
);
}
},
),
);
}
Widget appBar() {
return SizedBox(
height: AppBar().preferredSize.height,
child: Row(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Padding(
padding: const EdgeInsets.only(top: 8, left: 8),
child: Container(
width: AppBar().preferredSize.height - 8,
height: AppBar().preferredSize.height - 8,
),
),
Expanded(
child: Center(
child: Padding(
padding: const EdgeInsets.only(top: 4),
child:
Image.asset('assets/images/logo.png', fit: BoxFit.contain),
),
),
),
Padding(
padding: const EdgeInsets.only(top: 8, right: 8),
child: Container(
width: AppBar().preferredSize.height - 8,
height: AppBar().preferredSize.height - 8,
color: Colors.white,
child: Material(
color: Colors.transparent,
child: InkWell(
borderRadius:
BorderRadius.circular(AppBar().preferredSize.height),
child: Icon(
multiple ? Icons.dashboard : Icons.view_agenda,
color: AppTheme.dark_grey,
),
onTap: () {
setState(() {
multiple = !multiple;
});
},
),
),
),
),
],
),
);
}
}
as I have a widget which have the GridView.builder as the below code:
import 'package:aradi_online_vtwo/providers/properties.dart';
import 'package:flutter/material.dart';
import 'package:provider/provider.dart';
import '../providers/properties.dart';
import './property_item.dart';
class PropertiesGrid extends StatelessWidget {
final bool showFavs;
PropertiesGrid(this.showFavs);
#override
Widget build(BuildContext context) {
final productsData = Provider.of<Properties>(context);
final products = showFavs ? productsData.favoriteItems : productsData.items;
return GridView.builder(
padding: const EdgeInsets.all(10.0),
itemCount: products.length,
itemBuilder: (ctx, i) => ChangeNotifierProvider.value(
// builder: (c) => products[i],
value: products[i],
child: PropertyItem(
// products[i].id,
// products[i].title,
// products[i].imageUrl,
),
),
gridDelegate: SliverGridDelegateWithFixedCrossAxisCount(
crossAxisCount: 1,
childAspectRatio: 3 / 2,
crossAxisSpacing: 10,
mainAxisSpacing: 10,
), scrollDirection: Axis.horizontal,
);
}
}
I tried to set the height of the grid by wrapping it with a Container and set the height of it as to add more grids but it doesn't work.
and here's my Grid Item widget code:
import 'package:flutter/material.dart';
import 'package:provider/provider.dart';
import '../providers/property.dart';
class PropertyItem extends StatelessWidget {
#override
Widget build(BuildContext context) {
final property = Provider.of<Property>(context, listen: false);
return InkWell(
onTap: () => {},
child: Card(
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(15),
),
elevation: 7,
margin: EdgeInsets.all(2),
child: Stack(
children: <Widget>[
ClipRRect(
borderRadius: BorderRadius.only(
topLeft: Radius.circular(15),
topRight: Radius.circular(15),
),
// color: Colors.transparent,
child: Image.asset(
property.image,
fit: BoxFit.fill,
),
),
Positioned(
top: 8,
right: 8,
child: Consumer<Property>(
builder: (ctx, property, _) => IconButton(
icon: Icon(
property.isFavorite ? Icons.favorite : Icons.favorite_border,
),
color: Colors.red,
onPressed: () {
property.toggleFavoriteStatus();
},
),
),
),
Positioned(
right: 20,
top: 100,
child: Container(
width: 300,
color: Colors.black54,
padding: EdgeInsets.symmetric(
vertical: 5,
horizontal: 20,
),
child: Text(
property.title,
style: TextStyle(
fontSize: 20,
color: Colors.white,
),
softWrap: true,
overflow: TextOverflow.fade,
),
),
)
],
),
),
);
}
}
You'll need a column where each ListView or GridView is wrapped inside a SizedBox (if you have a specific height) and you also can use Expanded to take whatever available space (like the last one in the given example):
You can post the code below in dartpad.dev and see how it works:
import 'package:flutter/material.dart';
void main() {
runApp(MaterialApp(
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: MyApp(),
));
}
class MyApp extends StatelessWidget {
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(),
body: Column(
children: [
SizedBox(
height: 100,
child: ListView.builder(
scrollDirection: Axis.horizontal,
itemCount: 10,
itemBuilder: (c, i) {
return Card(
child: Container(
height: 100,
width: 100,
child: Center(child: Text("$i")),
),
);
},
),
),
Padding(
padding: const EdgeInsets.all(16.0),
child: Align(
child: Text("The Second List"),
alignment: Alignment.centerRight,
),
),
SizedBox(
height: 100,
child: ListView.builder(
scrollDirection: Axis.horizontal,
itemCount: 10,
itemBuilder: (c, i) {
return Card(
child: Container(
height: 100,
width: 100,
child: Center(child: Text("$i")),
),
);
},
),
),
Padding(
padding: const EdgeInsets.all(16.0),
child: Align(
child: Text("The Third List"),
alignment: Alignment.centerRight,
),
),
Expanded(
//height: 200,
child: GridView.builder(
gridDelegate: SliverGridDelegateWithFixedCrossAxisCount(
crossAxisCount: 2,
childAspectRatio: 3 / 2,
crossAxisSpacing: 10,
mainAxisSpacing: 10,
),
scrollDirection: Axis.vertical,
itemCount: 20,
itemBuilder: (c, i) {
return Card(
child: Container(
height: 100,
width: 100,
child: Center(child: Text("$i")),
),
);
},
),
),
