//here i am using wrap widget
child: Wrap(
children:[
Container(
child:checkBoxListTileModel[index]
.isCheck? Tags(

itemBuilder: (int index){
final item = _timingTagsList[index];
return ItemTags(
key: Key(index.toString()),

);
}),
))),
SizedBox(
width: 10,
),
],
))

use in initail function
setState(() {

Error displaying List view below container

I am trying to display Listview using Listview builder below the purple color(as seen in the image)container with the below code:
return Scaffold(
body: Column(
children: <Widget>[
Container(
height: 300,
decoration: BoxDecoration(
color: Colors.deepPurple,
borderRadius: BorderRadius.only(bottomLeft: Radius.circular(75.0)),
),
child: Column(
children: <Widget>[
Padding(
padding: const EdgeInsets.fromLTRB(0, 10, 200, 0),
child: Container(
padding: EdgeInsets.fromLTRB(0, 30,200,0),
child: IconButton(icon: Icon(Icons.arrow_back,),
color: Colors.black,
onPressed: () {
Navigator.pop(context);
},
),
),
),
SizedBox(height: 20,),
Text('Semester 1',
style: TextStyle(color: Colors.white,
fontSize: 30),
)
],
)
),
Container(
child: ListView.builder(
itemCount: 1,
itemBuilder: (BuildContext context, int index) {
return new Container(
child: new Center(
child: new Column(
crossAxisAlignment: CrossAxisAlignment.stretch,
children: <Widget>[
new Card(
child: new Container(
child: new Text("hello"),
padding: const EdgeInsets.all(20),
))
],
)));
}),
)
],
),
);
It returns a blank screen after running the code,without showing any error. I am not able to figure out the problem.
Please help!
If you use listview is small and inside Column then you should add
shrinkWrap: true in ListView
Column(
children: <Widget>[
ListView(
shrinkWrap: true, // use it
)
],
)
Or If your ListView Height is fix then use
Column(
children: <Widget>[
SizedBox(
height: 200, // constrain height
child: ListView(),
)
],
)
or If you want to fill all remaining space the use
Column(
children: <Widget>[
Expanded(
child: ListView(...),
)
],
)
Simply wrap the ListView in Expanded. The error here is that ListView doesn't know how to size itself (it has unbounded height from the Column). Using Expanded will tell it to fill up all the remaining space and fix the sizing problem
return Scaffold(
body: Column(
children: <Widget>[
Container(
height: 300,
decoration: BoxDecoration(
color: Colors.deepPurple,
borderRadius: BorderRadius.only(bottomLeft: Radius.circular(75.0)),
),
child: Column(
children: <Widget>[
Padding(
padding: const EdgeInsets.fromLTRB(0, 10, 200, 0),
child: Container(
padding: EdgeInsets.fromLTRB(0, 30,200,0),
child: IconButton(icon: Icon(Icons.arrow_back,),
color: Colors.black,
onPressed: () {
Navigator.pop(context);
},
),
),
),
SizedBox(height: 20,),
Text('Semester 1',
style: TextStyle(color: Colors.white,
fontSize: 30),
)
],
)
),
Container(
child: Expanded( // <-- wrap with expanded
child: ListView.builder(
itemCount: 1,
itemBuilder: (BuildContext context, int index) {
return new Container(
child: new Center(
child: new Column(
crossAxisAlignment: CrossAxisAlignment.stretch,
children: <Widget>[
new Card(
child: new Container(
child: new Text("hello"),
padding: const EdgeInsets.all(20),
))
],
)));
}),
),
)
],
),
);
Error is caused by Container that is wrapping ListView. You need to specify bounds for that Container.
return Scaffold(
body: Column(
children: <Widget>[
Container(
height: 300,
decoration: BoxDecoration(
color: Colors.deepPurple,
borderRadius:
BorderRadius.only(bottomLeft: Radius.circular(75.0)),
),
child: Column(
children: <Widget>[
Padding(
padding: const EdgeInsets.fromLTRB(0, 10, 200, 0),
child: Container(
padding: EdgeInsets.fromLTRB(0, 30, 200, 0),
child: IconButton(
icon: Icon(
Icons.arrow_back,
),
color: Colors.black,
onPressed: () {
Navigator.pop(context);
},
),
),
),
SizedBox(
height: 20,
),
Text(
'Semester 1',
style: TextStyle(color: Colors.white, fontSize: 30),
)
],
),
),
Container(
height: 300,
child: ListView.builder(
itemCount: 1,
itemBuilder: (BuildContext context, int index) {
return Container(
child: Center(
child: Column(
crossAxisAlignment: CrossAxisAlignment.stretch,
children: <Widget>[
Card(
child: Container(
child: Text("hello"),
padding: const EdgeInsets.all(20),
))
],
)));
}),
)
],
),
Above code should be working. Please note that, you don't need to specify "new" keyword in flutter.

Fit Container Widget Height to Parent Row Height

I have a web application with the following layout:

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:

BoxConstraints forces an infinite height.

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(

Expanded(

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;

Layout in list tile - flutter

Current output:
Expected output:
Code:
SizedBox(
width: 380,
height: 180,
child: Swiper(
itemCount: items.length,
itemBuilder: (context, index) {
return Column(
children: <Widget>[
Expanded(
child: Card(
child: ListTile(
title: Text(
'${items[index].title}',
),
subtitle: Text(
'${items[index].body}',
),
trailing: Column(
children: <Widget>[
CircleAvatar(
backgroundColor: HexColor("#0087a8"),
child: IconButton(
icon: Icon(Icons.add),
],
),
),
),
)
],
);
},
viewportFraction: 0.8,
scale: 0.9,
control: SwiperControl(color: Colors.white),
),
);
I am unable to create the icon button to be that way. As when i put in padding, it says that the pixels overflowed. I need to get the add button on the bottom right hand side.
As already pointed out, you shouldn't use a ListTile for this, as you want to use more than just a title, subtitle for your content.
The reason I've picked a Stack over a Column here, is that it allows you to safely use it in different size screens whilst assuring the view won't overflow. With Column, it would use the button diameter as the whole space to use (vertically), even though it is restrict to the right side of the box.
I believe this is what you're looking for.
class MyListTile extends StatelessWidget {
const MyListTile({
Key key,
}) : super(key: key);
#override
Widget build(BuildContext context) {
return Container(

Use custom widget for list item OR column from below code for single view. To align left and right you have to put your view in 'Align' as in below -
class _ItemsState extends State<Items> {
#override
Widget build(BuildContext context) {
// TODO: implement build
return Scaffold(
body: SizedBox(
width: 380,
height: 160,
child: Card(
child: ListView.builder(
itemCount: 1,
itemBuilder: (context, index) {
return
Padding(padding: EdgeInsets.all(10.0),child: Column(children: <Widget>[
Align(
alignment: Alignment.centerLeft,
child: Column(children: <Widget>[
Text(
'title',
style: TextStyle(fontSize: 20.0 , fontWeight: FontWeight.bold,),
),
Text(
'body',
style: TextStyle(fontSize: 14.0), )
]),
),
Align(
alignment: Alignment.centerRight,
child: CircleAvatar(
maxRadius: 20.0,
backgroundColor: Colors.blueGrey,
child: IconButton(
icon: Icon(Icons.add,
color: Colors.white,),
))
)
]));
}))));
}
}
