Why does the 1st two work but not the 3rd?? what's the alternative to add vertical divider with height that stretch to the max height of the row?
These 2 works
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
// crossAxisAlignment: CrossAxisAlignment.stretch,
children: [
Container(
child: Text('Kicukiro'),
),
Container(width: 1,color: Colors.black,height: double.infinity,),
Container(
padding: EdgeInsets.symmetric(horizontal: 10),
child: Text('Kicukiro'),
)
],
)
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
Expanded(
child: Container(
child: Text('Kicukiro'),
),
),
// Container(width: 1,color: Colors.black,height: double.infinity,),
Expanded(
child: Container(
padding: EdgeInsets.symmetric(horizontal: 10),
child: Text('Kicukiro'),
),
)
],
)
this does not work
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
Expanded(
child: Container(
child: Text('Kicukiro'),
),
),
Container(width: 1,color: Colors.black,height: double.infinity,),
Expanded(
child: Container(
padding: EdgeInsets.symmetric(horizontal: 10),
child: Text('Kicukiro'),
),
)
],
)
Test this and it will work
IntrinsicHeight(
child: Row(
crossAxisAlignment: CrossAxisAlignment.stretch,
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
Expanded(
child: Container(
child: const Text("Kicukiro", style: TextStyle(fontSize: 52),)),
),
Container(color:Colors.black, width: 1),
Expanded(
child: Container(
padding: const EdgeInsets.symmetric(horizontal: 10),
child: const Text("Kicukiro", style: TextStyle(fontSize: 52),)),
),
],
),
),
In the last screenshot please add the Container under an Expanded widget. Use children property under Row widget.
Here is an example code
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
crossAxisAlignment: CrossAxisAlignment.stretch,
children: <Widget>[
Expanded(
flex: 5,
child: Padding(
padding: EdgeInsets.all(10.0),
child: Center(
child: Text(
'This is question',
style: TextStyle(
fontSize: 25.0,
color: Colors.white,
),
),
),
),
),
Expanded(
child: Padding(
padding: EdgeInsets.all(10.0),
child: FlatButton(
//textColor: Colors.white,
color: Colors.green,
child: Text(
'True',
style: TextStyle(color: Colors.white, fontSize: 20.0),
),
onPressed: () {},
),
)),
Expanded(
child: Padding(
padding: EdgeInsets.all(10.0),
child: FlatButton(
//textColor: Colors.white,
color: Colors.red,
child: Text(
'False',
style: TextStyle(color: Colors.white, fontSize: 20.0),
),
onPressed: () {},
),
)),
]
The third is true, in fact, its existence in an SingleChildScrollView has created a problem
It is fixed by putting SizedBox in Row and giving it height
The reason for this problem is the size of the height of the container, which is determined by double.infinity and due to its presence in an SingleChildScrollView, it continues indefinitely and an error was created.
SingleChildScrollView(
child: SizedBox(
height: 250,
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
Expanded(child: Container(child: Text("Kicukiro"))),
Container(
width: 1,color: Colors.black,height: double.infinity,
),
Expanded(child: Container(
padding: EdgeInsets.symmetric(horizontal: 10),
child: Text("Kicukiro"))),
],
),
),
),
I'm new to Flutter and have been trying to clone a screen that requires a scroll architecture.Here is the link of the screen that i'm working on. https://i.stack.imgur.com/1OW2b.pngThe code is as below.PS: Ignore the fields that are incomplete. As soon as I get the scroll view, i'll add the functionalities afterwards.
Scaffold(
body: Column(
children: <Widget>[
Padding(
padding: const EdgeInsets.fromLTRB(15.0, 40.0, 15.0, 0),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
crossAxisAlignment: CrossAxisAlignment.center,
children: <Widget>[
Row(
crossAxisAlignment: CrossAxisAlignment.center,
children: const <Widget>[
Icon(Icons.menu),
Image(), //Asset image
],
),
Row(
children: <Widget>[
const Icon(Icons.notifications_none),
const SizedBox(width: 27.0),
CircleAvatar(
child: Text("JM"),
),
],
)
],
),
Row(
children: const <Widget>[
Icon(Icons.arrow_back),
SizedBox(width: 20.0),
Text("Public page"),
],
),
const SizedBox(
height: 20.0,
),
const Text(" Please fill the form following the proper order."),
const SizedBox(height: 10.0),
OverviewWidget(), //Widget with lots of TextFormField
SizedBox(height: 10.0),
DescriptionWidget(), //Widget with lots of TextFormField
],
),
),
Align([enter image description here][1]
alignment: Alignment.bottomCenter,
child: GestureDetector(
onTap: () {
print("Hello");
},
child: Container(
height: 130.0,
width: double.infinity,
alignment: Alignment.center,
decoration: BoxDecoration(

],
),
);
So far, i've only created the Overview and Description widgets and i'm already getting RenderFlex overflow error. I tried wrapping the very first Column widget with a SingleChildScrollView widget but it can be noticed that the Save button at the bottom should stay fixed. I tried wrapping the whole widget with Stack widget instead of a Column widget but it didn't help either. I also used ListView widget but got the same results.What shall I do to achieve this view?
I guess you had all the elements but did not quite manage to use them as needed.
Your screen is composed of two important layout:
A stack (containing a button on top of a scrollable widget)
The scrollable widget
The stack has to be a stack, the scrollable can be anything but in your case SingleChildScrollView+Column seems the best choice.
Here is the concrete implementation:
Scaffold(
body: Stack(
children: <Widget>[
Padding(
padding: const EdgeInsets.fromLTRB(15.0, 40.0, 15.0, 0),
child: SingleChildScrollView(
child: Padding(
padding: const EdgeInsets.only(bottom: 100.0),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
crossAxisAlignment: CrossAxisAlignment.center,
children: <Widget>[
Row(
crossAxisAlignment: CrossAxisAlignment.center,
children: <Widget>[
Icon(Icons.menu),
Container(
height: 100,
width: 100,
color: Colors.redAccent,
),
//Asset image
],
),
Row(
children: <Widget>[
const Icon(Icons.notifications_none),
const SizedBox(width: 27.0),
CircleAvatar(
child: Text("JM"),
),
],
)
],
),
Row(
children: const <Widget>[
Icon(Icons.arrow_back),
SizedBox(width: 20.0),
Text("Public page"),
],
),
const SizedBox(
height: 20.0,
),
const Text(" Please fill the form following the proper order."),
const SizedBox(height: 10.0),
Container(
height: 400,
color: Colors.blueAccent,
), //Widget with lots of TextFormField
SizedBox(height: 10.0),
Container(
height: 400,
color: Colors.greenAccent,
), //Widget with lots of TextFormField
],
),
),
),
),
Align(
alignment: Alignment.bottomCenter,
child: GestureDetector(
onTap: () {
print("Hello");
},
child: Container(
height: 130.0,
width: double.infinity,
alignment: Alignment.center,
decoration: BoxDecoration(
color: Colors.white,
boxShadow: [
BoxShadow(
color: Colors.grey.shade400,
blurRadius: 10,
spreadRadius: 1,
)
],
),
child: Container(
margin: const EdgeInsets.only(top: 10.0, bottom: 30.0),
decoration: BoxDecoration(
color: Colors.green.shade400,
borderRadius: BorderRadius.circular(35),
),
child: const Padding(
padding: EdgeInsets.symmetric(
vertical: 15.0,
horizontal: 150.0,
),
child: Text(
"Save",
style: TextStyle(
color: Colors.white, fontSize: 17, fontWeight: FontWeight.w600),
),
),
),
),
),
),
],
),
)
Note that you have to put a bottom padding inside the SingleChildScrollView to take into account the button. This is fine in your case since the button has a static height. However if you need something more fancy you might want to check How to create a scroll view with fixed footer with Flutter? as #Csisanyi suggested
Consider wrapping the Column with an Expanded widget
You can also check out this flutter doc. It addresses this common issue in detail.

I currently have a list made of Containers() (since I cannot use ListView because I need external scrolling), and it's working well except because in each of them, I have a Row(), with two Column() widgets. The first column should be limited print an image, and the second one, to show certain information in rows. It's a very typical way of doing lists, so I thought it shouldn't cause problems.
Thing is, that the second Text() widget in the second Column(), seems to always cause the upper Text() to shift to the right, causing an overflow and making the text unreadable, unreachable by the user. Look at this picture:
Yes, the titles are there (even if you can't see the second one). They are just quite shifted to the right. If I remove the description below, they show up correctly, at the left side, with just a little left padding. Thing is, these titles should be there no matter how elements are below, or at least, that's how I understand the Column() widget should work.
Take a look at the code:
getListItems(List<Artist> artistList) {
// Iterate through the whole Artists array and render a list item for each one
return artistList.map((Artist artist) {
return Container(
margin: EdgeInsets.only(top: 12),
height: 100,
color: Colors.grey[600],
child: Row(
children: <Widget>[
Padding(padding: EdgeInsets.only(left: 15)),
Column(
children: <Widget>[
Image(
width: 100,
height: 100,
fit: BoxFit.cover,
image: artist.avatar)
],
),
Padding(padding: EdgeInsets.only(top: 5)),
Column(
children: <Widget>[
Text(
artist.name,
style: TextStyle(fontSize: 18),
),
Padding(padding: EdgeInsets.only(top: 5)),
Text(artist.description, style: TextStyle(fontSize: 13))
],
)
],
));
}).toList();
What is wrong in this code? Thank you!
You can wrap the second column with Flexible to avoid overflow:
Container(
margin: EdgeInsets.only(top: 12),
height: 100,
color: Colors.grey[600],
child: Row(
children: <Widget>[
Padding(padding: EdgeInsets.only(left: 15)),
Column(
children: <Widget>[
Image(
width: 100,
height: 100,
fit: BoxFit.cover,
image: artist.avatar)
],
),
Flexible(
child: Column(
crossAxisAlignment: CrossAxisAlignment.center,
children: <Widget>[
Text(
artist.name,
style: TextStyle(fontSize: 18),
),
Padding(padding: EdgeInsets.only(top: 5)),
Text(artist.description, style: TextStyle(fontSize: 13))
],
),
)
],
))
You need to make some modifications to the Column which contains the Text widgets
Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Text(
artist.name,
style: TextStyle(fontSize: 18),
),
Padding(padding: EdgeInsets.only(top: 5)),
Container(
width: MediaQuery.of(context).size.width * 0.5, // can change "0.5" according to your requirement
child: Text(
artist.description,
style: TextStyle(fontSize: 13),
),
),
],
)
You can use Flexible() widget Wrap your text widget in flexible widget.
return Center(
child: Padding(padding: EdgeInsets.only(left: 50, right: 50),
child: Row(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Flexible(
child: Text('Hii....helloo....how r u?...here you can show multiple line.', textAlign: TextAlign.center,style: TextStyle(fontSize: 20.0, color: Colors.white))),
],
),
)
);
try Expanded
getListItems(List<Artist> artistList) {
// Iterate through the whole Artists array and render a list item for each one
return artistList.map((Artist artist) {
return Container(
margin: EdgeInsets.only(top: 12),
height: 100,
color: Colors.grey[600],
child: Row(
children: <Widget>[
Padding(padding: EdgeInsets.only(left: 15)),
Column(
children: <Widget>[
Image(
width: 100,
height: 100,
fit: BoxFit.cover,
image: artist.avatar)
],
),
Padding(padding: EdgeInsets.only(top: 5)),
Expanded(
child: Column(
children: <Widget>[
Text(
artist.name,
style: TextStyle(fontSize: 18),
),
Padding(padding: EdgeInsets.only(top: 5)),
Text(artist.description, style: TextStyle(fontSize: 13))
],
),
)
],
));
}).toList();
Use Expanded
class MyWidget extends StatelessWidget {
#override
Widget build(BuildContext context) {
return Container(
height: 100,
color: Colors.grey[600],
padding: const EdgeInsets.all(8.0),
child: Row(
children: [
Container(
width: 100,
decoration: BoxDecoration(
image: DecorationImage(
image: NetworkImage("https://picsum.photos/100"),
),
),
),
const SizedBox(width: 8.0),
Expanded(
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Text("Artist Name"),
const SizedBox(height: 8.0),
Text("Artist Description"),
],
),
),
],
),
);
}
}
first of all you can Define the container as a child of Expanded(the container in top of widget)
Expanded(
child:
Container(
margin: EdgeInsets.only(top: 12),
height: 100,
color: Colors.grey[600],......
or you can use
media query,media query, Defines the length or width according to the screen resolution of the phone
you gotta define media query for height or width
use the mediaqueryfor that, MediaQuery.of(context).size.height,
Container(
margin: EdgeInsets.only(top: 12),
height: `MediaQuery.of(context).size.height`,
color: Colors.grey[600],
child: Row(
children: <Widget>[
Padding(padding: EdgeInsets.only(left: 15)),
Column(
children: <Widget>[
Image(
width: 100,
height: 100,
fit: BoxFit.cover,
image: artist.avatar)
],
),
Padding(padding: EdgeInsets.only(top: 5)),
Column(
children: <Widget>[
Text(
artist.name,
style: TextStyle(fontSize: 18),
),
Padding(padding: EdgeInsets.only(top: 5)),
Text(artist.description, style: TextStyle(fontSize: 13))
],
)
],
));
}).toList();
if when you use the media query the overflowed error is showing you gotta say
MediaQuery.of(context).size.height - the pixels that error says pixels are overflowed
it means if error says overflowed by 128 pixels you gotta say
Container( height: MediaQuery.of(context).size.height -128 ,)
In my flutter app, I want to have a card and four boxes aligned horizontally with equal width and height inside it. Code follows ;
#override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
body: Container(
padding: EdgeInsets.fromLTRB(20,10,10,0),
height: 220,
width: double.maxFinite,
child: Card(
elevation: 5,
child: Column(
children: <Widget>[
Row(
children: <Widget>[
Expanded(
child: Container(
height:25,
color:Color(0xff6898F7),
child: Text('Online Pharmacy',
style:TextStyle(color: Color(0xffffffff)))
)
)
],
),
Row(
children: <Widget>[
Expanded(
flex: 1,
child: Container(
height: 150,
padding: EdgeInsets.only(top:40),
color: Colors.red,
child: Column(
children: <Widget>[
Image.asset("images/medicine.jpg"),
Center(
child: Row(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Padding(
padding:EdgeInsets.only(top:25),
child:Flexible(
child:Text('Medicine', style: TextStyle(color: Colors.white)),
),
),
],
),
),
],
)
),
),
],
),
],
),
The reason I used Flexible is that I wanted the text to be wrapped in multiple lines where necessary.
But I get this error :
════════ Exception caught by widgets library ═══════════════════════════════════════════════════════
The following assertion was thrown building Container(padding: EdgeInsets(0.0, 40.0, 0.0, 0.0), bg: BoxDecoration(color: MaterialColor(primary value: Color(0xfff44336))), constraints: BoxConstraints(0.0<=w<=Infinity, h=150.0)):
Incorrect use of ParentDataWidget.
Flexible widgets must be placed directly inside Flex widgets.
Flexible(no depth, flex: 1, dirty) has a Flex ancestor, but there are other widgets between them:
- Padding(padding: EdgeInsets(0.0, 25.0, 0.0, 0.0))
These widgets cannot come between a Flexible and its Flex.
The ownership chain for the parent of the offending Flexible was:
Padding ← Row ← Center ← Column ← Padding ← DecoratedBox ← ConstrainedBox ← Container ← Expanded ← Row ← ⋯
So how can I wrap the text properly ? Without the wrapping issue, code works well.
EDIT:
My intended layout seems to be like the image below :
Edit2:
Let me give you a more precise idea about the layout:
Edit3:
After getting a solution ( see here ) in chat room from pskink , I had the following layout. See that the red marked part does not get the text aligned in a centered fashion. How to align text in a centered way ?
try textAlign: TextAlign.center, inside text Widget
Please try this...

Just copy paste code and see what happening...

That my approach to what you need:
I have spent a couple hours just to create a reusable widget in flutter. My expected result is gonna be like this:
but I'm stuck to fill the opacity width depending on it's parent like this:
here's the code I've tried:
Stack(
children: <Widget>[
Container(
padding: const EdgeInsets.all(12),
child: Image.network(
"https://raw.githubusercontent.com/flutter/website/master/examples/layout/lakes/step5/images/lake.jpg",
fit: BoxFit.cover
)
),
Positioned(
left: 15,
bottom: 15,
child: Container(
decoration: BoxDecoration(
color: Color.fromRGBO(0, 0, 0, 0.5)
),
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
mainAxisSize: MainAxisSize.max,
children: <Widget>[
Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
new Text("TITLE", style: new TextStyle(fontSize: 28, color: Colors.white)),
new Text("Sub Title", style: new TextStyle(fontSize: 20, color: Colors.white))
],
),
FlatButton(
color: Colors.red[400],
highlightColor: Colors.red[900],
onPressed: (){},
child: new Text("Book Now", style: new TextStyle(fontSize: 28, color: Colors.white)),
)
],
),
)
)
],
)
any suggestion?
Short answer:
You need to add right property in your Positioned widget. Like this
Positioned(
left: 15,
bottom: 15,
right: 0,
...)
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(title: Text("Title")),
body: Container(
width: 300,
height: 300,
child: Stack(
alignment: Alignment.bottomLeft,
children: <Widget>[
Image.asset(
"assets/images/chocolate_pic.png",
width: 300,
height: 300,
fit: BoxFit.cover,
),
Container(
color: Colors.black.withOpacity(0.5),
padding: const EdgeInsets.all(8.0),
child: Column(
mainAxisSize: MainAxisSize.min,
crossAxisAlignment: CrossAxisAlignment.stretch,
children: <Widget>[
Text("Awesome", style: TextStyle(fontSize: 28)),
Text("Chocolate", style: TextStyle(fontSize: 22)),
],
),
)
],
),
),
);
}
Instead of this
Row(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
mainAxisSize: MainAxisSize.max,
children: <Widget>[
Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
new Text("TITLE", style: new TextStyle(fontSize: 28, color: Colors.white)),
new Text("Sub Title", style: new TextStyle(fontSize: 20, color: Colors.white))
],
),
FlatButton(
color: Colors.red[400],
highlightColor: Colors.red[900],
onPressed: (){},
child: new Text("Book Now", style: new TextStyle(fontSize: 28, color: Colors.white)),
)
],
),
You can use ListTile widget inside the positioned and container which has title, subtitle and trailing(book now button can be placed here). And make the background color of container to black/white with opacity.
