mainAxisSpacing: 4.0),
itemBuilder: (BuildContext context, int index) {
return Column(children: [
const CircleAvatar(
radius: 24, // Image radius

I tried SingleChildScrollView in child but it didnt helped.

You are using scrollDirection: Axis.horizontal, therefore it is scrolling horizontally. you can remove it or set to scrollDirection: Axis.vertical, on GridView.
child: GridView.builder(
scrollDirection: Axis.vertical, //this by default
padding: const EdgeInsets.only(left: 15),
No need to provide fixed heigth, use Expnaded widget to get available height, follow this snippet
Widget build(BuildContext context) {
return Scaffold(
body: Column(
children: [
Container(
padding: const EdgeInsets.symmetric(horizontal: 15, vertical: 10),
alignment: Alignment.topLeft,
child: Text(
'Keep shopping for',
style: const TextStyle(
fontSize: 20,
),
),
),
Expanded(
child: GridView.builder(
padding: const EdgeInsets.only(left: 15),
itemCount: 44,
gridDelegate: const SliverGridDelegateWithFixedCrossAxisCount(
crossAxisCount: 1,
childAspectRatio: 1.4,
mainAxisSpacing: 10,
),
itemBuilder: (context, index) {
// final product = productList![index];
return GestureDetector(
onTap: () {},
child: Column(
children: [
SizedBox(
height: 130,
child: DecoratedBox(
decoration: BoxDecoration(
border: Border.all(
color: Colors.black12,
width: 0.5,
),
),
child: Padding(
padding: const EdgeInsets.all(10),
// child: Image.network(
// product.images[0],
// ),
),
),
),
Container(
alignment: Alignment.topLeft,
padding: const EdgeInsets.only(
left: 0,
top: 5,
right: 15,
),
child: Text(
"name",
maxLines: 1,
overflow: TextOverflow.ellipsis,
),
),
],
),
);
},
),
)
],
),
);
}

How to add RefreshIndicator with FutureBuilder on Flutter

I need to implement the pull to refresh action, on a future builder using refresh indicator widget. First of all, i know there are multiple threads on this topic. But I still couldn't. Here are my codes on the subject:
final QuerySnapshot<Map<String, dynamic>> querySnapshot =
snapshot.data as QuerySnapshot<Map<String, dynamic>>;
return ListView(
physics: const BouncingScrollPhysics(),
children: <Widget>[
Container(
margin: const EdgeInsets.only(top: 28.8, bottom: 16.8),
height: 714.8,
child: FutureBuilder<List<FirabaseWeatherModel>>(
future: chnageList(querySnapshot),
builder: (BuildContext context,
AsyncSnapshot<dynamic> snapshot) {
if (snapshot.hasData) {
ListView.builder(
itemCount: firabseModelList.length,
padding:
const EdgeInsets.only(left: 28.8, right: 12),
scrollDirection: Axis.vertical,
physics: const BouncingScrollPhysics(),
itemBuilder: (context, index) {
return Container(
height: 214.8,
width: 188.4,
margin: const EdgeInsets.only(
right: 16.8, bottom: 50),
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(9.6),
image: DecorationImage(
fit: BoxFit.cover,
image: CachedNetworkImageProvider(
querySnapshot.docs[index]
.data()['image'],
maxHeight: 200,
maxWidth: 200),
),),
child: Stack(
children: <Widget>[
GestureDetector(
onTap: () => gotoPage(querySnapshot
.docs[index]
.data()['title'])),
],),);},);
} else if (snapshot.connectionState ==
ConnectionState.waiting) {
return const Center(
child: CircularProgressIndicator(),
);}
return ListView.builder(
itemCount: firabseModelList.length,
padding: const EdgeInsets.only(left: 28.8, right: 12),
scrollDirection: Axis.vertical,
physics: const BouncingScrollPhysics(),
itemBuilder: (context, index) {
return Container(
height: 214.8,
width: 188.4,
margin: const EdgeInsets.only(
right: 16.8, bottom: 50),
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(9.6),
image: DecorationImage(
fit: BoxFit.cover,
image: CachedNetworkImageProvider(
querySnapshot.docs[index].data()['image'],
maxHeight: 200,
maxWidth: 200),
),),
child: Stack(
children: <Widget>[
GestureDetector(
onTap: () => gotoPage(querySnapshot
.docs[index]
.data()['title'])),
Positioned(
child: ClipRRect(
child: Container(
height: 80,
alignment: Alignment.centerLeft,
child: Column(
children: [
Align(
child: Container(
alignment: Alignment.topCenter,
child: Text(
querySnapshot.docs[index]
.data()['tr'],
style: const TextStyle(
fontSize: 15,
),),),),
Row(
children: <Widget>[
Expanded(
child: getImage(
querySnapshot.docs[index]
.data()['zposition1']
.toString(),
150),
),],),],),),),),],),);},);}),),],);
I have uploaded all the code in case you want to try it yourself using all the codes. Where should i use these refresh indicator codes:
RefreshIndicator(
onRefresh: () {},),

add key
GlobalKey _key = GlobalKey();
Then assign the previous key to the top widget
return RefreshIndicator(
onRefresh: _refresh,
child: Container(
key: _key,
child: ListView(
physics: AlwaysScrollableScrollPhysics(),
children: [
// do your stuff
],
),
),
);
Then refresh function, as you should update the key
Future<void> _refresh() async {
if (mounted) {
_key = GlobalKey();
setState(() {});
}
Future.value(null);
}

How to add text on top of Dart Flutter gridView?

I made an application like this:
I want to add a little info text on top of this gridView structure. How can I do it? I'm a beginner and I just couldn't do it.
Codes:
body: Container(
padding: EdgeInsets.all(7),
child: GridView.builder(
gridDelegate: const SliverGridDelegateWithFixedCrossAxisCount(
crossAxisCount: 2,
crossAxisSpacing: 10,
mainAxisSpacing: 10,
),
itemCount: subjects.length,
itemBuilder: (BuildContext context, int index) {
return Padding(
padding: const EdgeInsets.all(2.0),
child: Container(
child: InkWell(

crossAxisAlignment: CrossAxisAlignment.center,
mainAxisAlignment: MainAxisAlignment.center,
children: [
Image.asset(subjects[index].subjectImage, fit: BoxFit.cover, height: 50, width: 50,),
SizedBox(height: 15,),
Text(subjects[index].subjectName, style: TextStyle(fontSize: 20, fontWeight: FontWeight.w500),),
],
),
),
onTap: () {},
),
),
);
},
),
How can I do it? Thanks in advance.

Try below code. I have added text like Text("1234567890")
body: Container(
padding: EdgeInsets.all(7),
child: Column(
children: [
Text("1234567890"), //<------------
Expanded(
child: GridView.builder(
gridDelegate: SliverGridDelegateWithFixedCrossAxisCount(
crossAxisCount: 2,
crossAxisSpacing: 10,
mainAxisSpacing: 10,
),
itemCount: subjects.length,
itemBuilder: (BuildContext context, int index) {
return Padding(
padding: const EdgeInsets.all(2.0),
child: Container(
child: InkWell(
child: Container(
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(10),
border: Border.all(color: Colors.black),
),
child: Column(
crossAxisAlignment: CrossAxisAlignment.center,
mainAxisAlignment: MainAxisAlignment.center,
children: [
Image.asset(
subjects[index].subjectImage,
fit: BoxFit.cover,
height: 50,
width: 50,
),
SizedBox(
height: 15,
),
Text(
subjects[index].subjectName,
style: TextStyle(
fontSize: 20, fontWeight: FontWeight.w500),
),
],
),
),
onTap: () {},
),
),
);
},
),
),
],
),
);

You can use #DholaHardik's answer. Just need to wrap the Grid View Builder to a Sized Box and give it a height let's say height = MediaQuery.of(context).size.height and if the error says Overyflow by say 45 pixels.. You can change height to MediaQuery.of(context).size.height - 45;

I can't Scroll my Screen when using SingleChildScollView in flutter

I am trying to make my main screen scrollable using SingleChildScrollView but it's not working as expected
here is my code:
SingleChildScrollView(
child: Column(
children: [
Row(...),
Container(
child: Column(
children: [
Text(...),
SizedBox(
child: ListView.builder(
scrollDirection: Axis.vertical,
shrinkWrap: true,
itemBuilder: (context, count) {
return Container(
height: 300,
child: Text("hi there $count"),
);
},
itemCount: 4,
),
)
],
),
)
],
),
);

change the column to list view
like this
SingleChildScrollView(
child: Column(
children: [
Row(...),
Container(
child: ListView(
children: [
Text(...),
SizedBox(
child: ListView.builder(
scrollDirection: Axis.vertical,
shrinkWrap: true,
itemBuilder: (context, count) {
return Container(
height: 300,
child: Text("hi there $count"),
);
},
itemCount: 4,
),
)
],
),
)
],
),
);
try this code

4 Horizontal Listviews in a Scrollable Column in FLutter

I need 4 Scrollable Horizontal Listviews in a vertically scrollable column.
I have tried multiple things again and again but the vertical scrolling just doesn't seem to work.
This is the kind of layout I want.
Container(
padding: EdgeInsets.all(20),
child: SingleChildScrollView(
scrollDirection: Axis.vertical,
child: Column(
mainAxisSize: MainAxisSize.min,
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: [
Align(
alignment: Alignment.bottomLeft,
child: Text("Some Text",style: TextStyle(
fontWeight: FontWeight.bold,
fontSize: 18
),),
),
SizedBox(height:10),
Container(
height: MediaQuery.of(context).size.height/6.8,
child: ListView.builder(
scrollDirection: Axis.horizontal,
shrinkWrap: true,
itemCount: snapshot.data.length,
itemBuilder: (context, index){
return widget(
);
}),
),
Align(
alignment: Alignment.bottomLeft,
child: Text("Some Text",style: TextStyle(
fontWeight: FontWeight.bold,
fontSize: 18
),),
),
SizedBox(height:10),
Container(
height: MediaQuery.of(context).size.height/6.8,
child: ListView.builder(
scrollDirection: Axis.horizontal,
shrinkWrap: true,
itemCount: snapshot.data.length,
itemBuilder: (context, index){
return widget(
);
}),
),Align(
alignment: Alignment.bottomLeft,
child: Text("Some Text",style: TextStyle(
fontWeight: FontWeight.bold,
fontSize: 18
),),
),
SizedBox(height:10),
Container(
height: MediaQuery.of(context).size.height/6.8,
child: ListView.builder(
scrollDirection: Axis.horizontal,
shrinkWrap: true,
itemCount: snapshot.data.length,
itemBuilder: (context, index){
return widget(
);
}),
),Align(
alignment: Alignment.bottomLeft,
child: Text("Some Text",style: TextStyle(
fontWeight: FontWeight.bold,
fontSize: 18
),),
),
SizedBox(height:10),
Container(
height: MediaQuery.of(context).size.height/6.8,
child: ListView.builder(
scrollDirection: Axis.horizontal,
shrinkWrap: true,
itemCount: snapshot.data.length,
itemBuilder: (context, index){
return widget(
);
}),
),Align(
alignment: Alignment.bottomLeft,
child: Text("Some Text",style: TextStyle(
fontWeight: FontWeight.bold,
fontSize: 18
),),
),
SizedBox(height:10),
Container(
height: MediaQuery.of(context).size.height/6.8,
child: ListView.builder(
scrollDirection: Axis.horizontal,
shrinkWrap: true,
itemCount: snapshot.data.length,
itemBuilder: (context, index){
return widget(
);
}),
),
);
Can anyone tell me what I am doing wrong?
I have been stuck in this for a long time now.
The horizontal list does scroll but the vertical scroll is not working.

Try using SingleChildScrollView and Row instead of ListView
For example,
class Home extends StatelessWidget {
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text("4 Horizontals"),
),
body: SafeArea(
child: SingleChildScrollView(
child: Column(
children: [
SingleChildScrollView(
scrollDirection: Axis.horizontal,
child: Row(
children: List.generate(10, (index) => getWid()),
),
),
SizedBox(height: 10),
SingleChildScrollView(
scrollDirection: Axis.horizontal,
child: Row(
children: List.generate(10, (index) => getWid()),
),
),
SizedBox(height: 10),
SingleChildScrollView(
scrollDirection: Axis.horizontal,
child: Row(
children: List.generate(10, (index) => getWid()),
),
),
SizedBox(height: 10),
SingleChildScrollView(
scrollDirection: Axis.horizontal,
child: Row(
children: List.generate(10, (index) => getWid()),
),
),
],
),
),
),
);
}
Widget getWid() {
return Container(
color: Colors.pink,
width: 200,
height: 200,
padding: EdgeInsets.all(10),
margin: EdgeInsets.all(5),
child: Center(
child: Text(
"Hello",
style: TextStyle(
color: Colors.white,
fontSize: 30
),
),
),
);
}
}
