Building a card widget [Flutter] - dart

I am trying to build my own card within flutter however I keep getting the error of child not being defined.
The type of card I am trying to build can be seen here
Is it also possible to link me to a tutorial that properly explains when to use child and children as this seems to be my issue at this time.
My code can be seen below:
List<Widget> cardlist = <Widget>[
new Card(
child: new Column(
children: <Widget>[
new Row(
child: new CircleAvatar(
backgroundImage: new AssetImage('images/pic.jpg'),
radius: 100.0,
),
)
],
child: new Row(
child: new CircleAvatar(
backgroundImage: new AssetImage('images/pic.jpg'),
radius: 100.0,
),
child: new Text(
'News Location',
style: new TextStyle(
fontSize: 20.0,
fontWeight: FontWeight.bold,
color: Colors.black,
),
),
),
child: new Image.asset(
'images/lake.jpg',
height: 240.0,
fit: BoxFit.cover,
),
child: new Text(
'News Headline',
style: new TextStyle(
fontSize: 20.0,
fontWeight: FontWeight.bold,
color: Colors.black,
),
),
child: new Text(
'News Summary',
style: new TextStyle(
fontSize: 20.0,
fontWeight: FontWeight.bold,
color: Colors.black,
),
),
child: new Row(
child: new CircleAvatar(
backgroundImage: new AssetImage('images/pic.jpg'),
radius: 100.0,
),
child: new Text(
'News Source',
style: new TextStyle(
fontSize: 20.0,
fontWeight: FontWeight.bold,
color: Colors.black,
),
),
child: new Text(
'12 hours ago',
style: new TextStyle(
fontSize: 20.0,
fontWeight: FontWeight.bold,
color: Colors.black,
),
),
),
),
)
];

I think you want something like what I have below, not sure it is exactly right but it should give you a starting point. Basically you need to understand when to use child and when children, and the correct syntax. just think about the widget you are using and if it could contain one (child) or more than one (children) child widgets, or look at the docs to see what it takes :)
body: new Center(
child: new Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
new Card(
child: new Column(
children: [
new Row(
children: [
new CircleAvatar(
backgroundImage: new AssetImage('images/pic.jpg'),

when i click on a picture it has to go to a new page which automatically change orientation to Landscape ans when i click back to previous page it changes again.
You are using a StatelessWidget, so you cannot override initState and dispose. First, convert your StatelessWidget to StatefulWidget, then implement the code provided by the other answer.
class ImageScreen extends StatefulWidget {
#override
ImageScreenState createState() => ImageScreenState();
}
class ImageScreenState extends State<ImageScreen> {
#override
void initState(){
super.initState();
SystemChrome.setPreferredOrientations([
DeviceOrientation.landscapeRight,
DeviceOrientation.landscapeLeft,
]);
}
#override
dispose(){
SystemChrome.setPreferredOrientations([
DeviceOrientation.landscapeRight,
DeviceOrientation.landscapeLeft,
DeviceOrientation.portraitUp,
DeviceOrientation.portraitDown,
]);
super.dispose();
}
#override
Widget build(BuildContext context) {
Widget imageSlider = Container(
height: MediaQuery.of(context).size.height,
child: Carousel(
boxFit: BoxFit.cover,
images: [
AssetImage('assets/images/houses/house.jpg'),
AssetImage('assets/images/houses/house1.jpg'),
AssetImage('assets/images/houses/house2.jpg'),
AssetImage('assets/images/houses/house3.jpg'),
AssetImage('assets/images/houses/house4.jpg'),
],
autoplay: false,
dotBgColor: Colors.transparent,
dotSize: 0,
),
);
return Scaffold(
body: GestureDetector(
child: Center(
child: Hero(
tag: 'carouselHero',
child: imageSlider,
),
),
onTap: () {
Navigator.pop(context);
},
),

How to position elements inside a ListView?

Good morning. I made this screen and it works like a charm on high resolutions. Problem is, I want to support lower resolutions like Nexus 4 (768x1280).
So when I run this on an emulator (Nexus 4 size) and I touch the input fields, the keyboard either: blocks the inputs, or moves the two buttons at the bottom and overlaps them on something else.
So, to solve it I wrapped the entire layout on a ListView(), but now the bottom buttons, which are wrapped on a Row(), just won't stay at the bottom.
This is my code without the ListView and working on high res, but not on low:
return Form(
Stack(
Center(
Column(
...
),
),
Align(
alignment: Alignment.bottomCenter,
child: Row(
...
),
),
),
);
This is how it looks with resizeToAvoidBottomPadding: false
And this is how it looks with the value set to true
Thanks, everyone.
Did you try to use SingleChildScrollView ?
It is a widget for making the page able to resize the height and as well scrolling , for the listview thats not what is the listview for , you should add listview when you get an unknown amount of data,
We don't normally use it to just adjust the view.
ok so i edited the code as in here and i can scroll normally after the keyboard pop up and the view is good and i can click on the button normally try it.
Widget formWidget(){
return new Scaffold(
// appBar: AppBar(
// // Here we take the value from the MyHomePage object that was created by

In your Scaffold can you try this.
Scaffold(
resizeToAvoidBottomInset: false,
...
);
I position two elements in the center and bottom of the screen by this code.

Row RenderFlex overflowed by 76 pixels on the right

Below are my code I always got some pixel overflowed on right size. I was playing with Expanded and Fixable widgets as well as mainAxisSize of row and column too.
Look at the code:
Widget productDisplayListView(List<Products> listOfProduct, int index) {
return Container(
margin: EdgeInsets.all(7),
child: Container(
child: Card(
elevation: 4,
child: Container(
padding: EdgeInsets.all(6),
child: Row(
mainAxisSize: MainAxisSize.min,
mainAxisAlignment: MainAxisAlignment.start,
children: <Widget>[
Container(
height: 110,
width: 90,
child: Image.network(
listOfProduct[index].thumbnail ?? '',
fit: BoxFit.cover,
),
),
Container(
padding: EdgeInsets.all(5),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Row(
mainAxisSize: MainAxisSize.min,
children: <Widget>[
Container(
padding: EdgeInsets.zero,
margin: EdgeInsets.zero,
height: 20,
width: 20,
child: Icon(
Icons.crop_square,
color: Colors.red,
size: 18,
),
),
Flexible(
child: Text(
'The overflowing RenderFlex has an orientation of Axis.horizontal.',
overflow: TextOverflow.ellipsis,
softWrap: true,
style: TextStyle(
fontSize: 13,
fontWeight: FontWeight.w600,
color: Theme.of(context).primaryColor),
),
)
],
),
SizedBox(height: 5),
Text(
'The overflowing RenderFlex has an orientation of Axis.horizontal.',
maxLines: 1,
style: TextStyle(
fontSize: 12,
fontWeight: FontWeight.w500,
color: Colors.grey),
),
SizedBox(height: 5),
Text(
'₹${listOfProduct[index].price ?? ''}',
style: TextStyle(
fontSize: 13,
fontWeight: FontWeight.w700,
color: Colors.black),
)
],
),
)
],
),
),
),
),
);
}
I tried with many Que./Ans. on stackOverFlow but But didn't get success.
Updated Code with Fixed Overflow Error. Have to made quite a change in your Widget Tree.
Widget productDisplayListView() {
return Card(
elevation: 4,
child: Container(
padding: EdgeInsets.all(6),
child: Row(
children: <Widget>[
Container(
height: 110,
width: 90,
child: Image.network(
'https://placeimg.com/250/250/any',
fit: BoxFit.cover,
),
),
SizedBox(
width: 5.0,
),
Flexible(
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
MergeSemantics(
child: Row(
children: <Widget>[
Icon(
Icons.crop_square,
color: Colors.red,
size: 18,
),
Flexible(
child: Text(
'The overflowing RenderFlex has an orientation of Axis.horizontal.',
overflow: TextOverflow.ellipsis,
softWrap: true,
style: TextStyle(
fontSize: 13,
fontWeight: FontWeight.w600,
color: Theme.of(context).primaryColor),
),
)
],
),
),
SizedBox(height: 5),
Text(
'The overflowing RenderFlex has an orientation of Axis.horizontal.',
maxLines: 1,
style: TextStyle(
fontSize: 12,
fontWeight: FontWeight.w500,
color: Colors.grey),
),
SizedBox(height: 5),
Text(
'₹ 10,000',
style: TextStyle(
fontSize: 13,
fontWeight: FontWeight.w700,
color: Colors.black),
)
],
),
)
],
),
),
);
}
OutPut:
Check Your Rows Add Column Widgets. If any row or column widget has a single flexible child an error will occur
Doing like this should fix your problem:-
..... Container(
padding: EdgeInsets.all(5),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Row(
mainAxisSize: MainAxisSize.min,
children: <Widget>[
Flexible(
child: Container(
padding: EdgeInsets.zero,
margin: EdgeInsets.zero,
height: 20,
width: 20,
child: Icon(
Icons.crop_square,
color: Colors.red,
size: 18,
),
),
),
Flexible(
child: Text(
'The overflowing RenderFlex has an orientation of Axis.horizontal.',
overflow: TextOverflow.ellipsis,
softWrap: true,
style: TextStyle(
fontSize: 13,
fontWeight: FontWeight.w600,
color: Theme.of(context).primaryColor),
),
)
],
),
SizedBox(height: 5),
Flexible(
child: Text(
'The overflowing RenderFlex has an orientation of Axis.horizontal.',
maxLines: 1,
style: TextStyle(
fontSize: 12,
fontWeight: FontWeight.w500,

I have a list of containers wrapped in a listview, I need to give a onTap functionality like when the user taps on the container it should give me a value of that particular container, below is my code and I tried using Inkwell function but it throws an error saying vertical portview. Help me out and thanks in advance.
dynamic _allVehiclesDataView = new ListView(
children: List.generate(this._allVehiclesData.length,
(i) => new Container(
decoration: new BoxDecoration(
border: Border(
bottom: BorderSide(width: 1.0, color: Colors.grey[300]),
),
),
padding: const EdgeInsets.all(32.0),
child: Row(
children: [
Expanded(
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Container(
padding: const EdgeInsets.only(bottom:5.0),
child: Text(
this._allVehiclesData[i]["vehicle"]["registration"],
style: TextStyle(
fontWeight: FontWeight.bold,
fontSize: 20.0,
),
),
),
Text(
'Location :',
style: TextStyle(
fontSize: 15.0,
color: Colors.grey,
),
),
Text(
(this._allVehiclesData[i]["address"] == null ||
this._allVehiclesData[i]["address"] == 'Not determined') ?
"No data available" : ""+this._allVehiclesData[i]["address"]["LongLabel"],
style: TextStyle(
fontSize: 13.0,
fontWeight: FontWeight.bold,
),
),
Text(
'Last known update :',
style: TextStyle(
fontSize: 15.0,
color: Colors.grey[500],
),
),
Text(
(this._allVehiclesData[i]["deviceTime"]),
style: TextStyle(
fontSize: 13.0,
fontWeight: FontWeight.bold,
),
),
this._allVehiclesData[i]["fuel"] != "null"?
new Row(
children: <Widget>[
Text(
'Fuel Level :',
style: TextStyle(
fontSize: 15.0,
color: Colors.grey[500],
),
),
new Container(
decoration: new BoxDecoration(
shape : BoxShape.circle,
border: new Border.all(
color: Colors.blue[300],
width: 5.0,
)
),
),
Text(
(this._allVehiclesData[i]["fuel"].toString()),
style: TextStyle(
fontSize: 13.0,
fontWeight: FontWeight.bold,
),
),
],
) : Text(''),
this._allVehiclesData[i]["temperature"] != "null" ?
new Row(
children: <Widget>[
Text(
'Temp :',
style: TextStyle(
fontSize: 15.0,
color: Colors.grey[500],
),
),
new Container(
decoration: new BoxDecoration(
shape : BoxShape.circle,
border: new Border.all(
color: Colors.red[300],
width: 5.0,
)
),
),
Text(
(' '+this._allVehiclesData[i]["temperature"].toString()+' C'),
style: TextStyle(
fontSize: 13.0,
fontWeight: FontWeight.bold,
),
),
],
):Text(""),
],
),
),
status(i),
// new InkWell(),
],
),
),
),
);
You can use the GestureDetector for the same
Wrap your Container in a GestureDetector with an onTap callback
GestureDetector(
// When the child is tapped, do your work
onTap: () {
...
...
},
// Container
child: Container(
...
),
);

Flutter listview items are going out of view.

My Listview items are going out of the view and showing in ListTile that is below my Listview, I am not getting what I am doing wrong in my code. Please have a look at below images, you can see ending point of list view and in another image my items are going out of this ending point. I am posting my code below, please have a look and help me to resolve this issue.
Here is my Listview items are going out of the view.
Below is the code:
class _CartFinalSummaryState extends State<CartFinalSummary> {
final cartSummary = new StoreConnector<List<CartItem>, List<CartItem>>(
converter: (store) => store.state,
builder: (context, list) => new Padding(
padding: const EdgeInsets.all(8.0),
child: new Container(
margin: new EdgeInsets.only(top: 5.0, left: 5.0, right: 5.0),
child: new Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: <Widget>[
new Text(
"Quantity: (${getTotalQuantity(list)})",
style: new TextStyle(
fontSize: 15.0,
fontWeight: FontWeight.w700
),
),
],
),
),
),);
final listCartItem = new StoreConnector<List<CartItem>,
List<CartItem>>(
converter: (store) => store.state,
builder: (context, list) => new Container(
child: new Flexible(
child: new Stack(
children: <Widget>[
new ListView.builder(
scrollDirection: Axis.vertical,
itemCount: list ==0 ? null : list.length,
itemBuilder: (context, index){
return new Column(
children: <Widget>[
new ListTile(
title: new Text(
list[index].product
.name.toString(),
style: new TextStyle(fontWeight: FontWeight.bold,
fontSize: 18.0),),
subtitle: new Text(list[index].quantity.toString()
+ " x " + list[index].product.price.toString()),
trailing: new Text("€"+(list[index].product.price *
list[index].quantity).toString(),
style: new TextStyle(fontWeight: FontWeight.bold,
fontSize: 18.0)),
),
new Divider(
)
],
);
}),
],
),
),
));
#override
Widget build(BuildContext context) {
return new Scaffold(
bottomNavigationBar: new GestureDetector(
onTap: () {
/*Navigator.push(
context,
new MaterialPageRoute(builder: (context) =>
new SelectTable()));*/
},
child:new StoreConnector<List<CartItem>, List<CartItem>>(
converter: (store) => store.state,
builder: (context, list) => new Container(
padding: const EdgeInsets.all(10.0),
color: Colors.green,
child: new Row(
crossAxisAlignment: CrossAxisAlignment.center,
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
new GestureDetector(
child: new Text("Proceed to Pay ${
"( €"+getTotal(list).toStringAsFixed(2)+" )"}", style:
new TextStyle(
color: Colors.white,
fontSize: 18.0),),
)
],
)
)),
),
appBar: new AppBar(
iconTheme: new IconThemeData(color: Colors.white),
title: new Text('Cart Summary', style: new TextStyle(
color: Colors.white
),),
),
body: new Container(
child: new Column(
children: <Widget>[
cartSummary,
new Divider(
color: Colors.black,
height: 3.0,
),
listCartItem,
new Divider(
color: Colors.black,
height: 5.0,
),
new ListTile(
title: new Text("Table Selected",
style: new TextStyle(fontWeight: FontWeight.bold,
fontSize: 18.0)),
trailing: new Text("5",
style: new TextStyle(fontWeight: FontWeight.bold,
fontSize: 18.0)),
),
new Divider(
color: Colors.black,
),
new ListTile(
title: new Text("Sub Total",
style: new TextStyle(fontWeight: FontWeight.bold,
fontSize: 18.0)),
trailing: new Text("5",
style: new TextStyle(fontWeight: FontWeight.bold,
fontSize: 18.0)),
),
],
),
),
);
}
}
I've resolved the issue by replacing this piece of code. I am still not sure what was the problem, I think the ListTiles that I was using were transparent, I've used ListTile as child of Container widget and set the background color of container.
new Divider(
color: Colors.black,
height: 0.1,
),
new Container(
color: const Color(0xFFD6D6D6),
child: new ListTileTheme(
child: new ListTile(
onTap: (){
Navigator.pushReplacement(
context,
new MaterialPageRoute(builder: (context) =>
new SelectTable()));
},
title: new Text("Table Selected",
style: new TextStyle(fontWeight: FontWeight.bold,
fontSize: 17.0)),
trailing: new Text(widget.tableNumber.toString(),
style: new TextStyle(fontWeight: FontWeight.bold,
fontSize: 17.0)),
),
),
),
new Divider(
height: 0.1,
color: Colors.black,
),
new Container(
color: const Color(0xFFD6D6D6),
child: new ListTile(
title: new Text("Grand Total",
style: new TextStyle(fontWeight: FontWeight.bold,
fontSize: 17.0)),
trailing: new Text("€"+getTotal(list).toString(),
style: new TextStyle(fontWeight: FontWeight.bold,
fontSize: 17.0)),
),
),
