How to keep column in line in Flutter (Fixing constraints)? - flutter

I have a column in and in column i have rows. I want to make rows start in same line.The problem is i cannot put in line the rows.Normally without rows column's texts were in line but i needed to put icons in front of the text so make them as row.I need help with this problem.
This is my code:
Container(
margin: const EdgeInsets.all(20),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
SizedBox(
height: 58,
),
Container(
margin: const EdgeInsets.only(bottom: 20),
child: Row(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Image.asset('assets/images/foldertree.png', scale: 3),
Text('Sınırsız belge',
textAlign: TextAlign.center,
style:
TextStyle(fontSize: 18, color: Colors.white)),
],
)),
Container(
margin: const EdgeInsets.only(bottom: 20),
child: Row(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Image.asset('assets/images/t.png', scale: 3),
Text('Metin Algılama (OCR)',
textAlign: TextAlign.center,
style:
TextStyle(fontSize: 18, color: Colors.white)),
],
)),
Container(
margin: const EdgeInsets.only(bottom: 20),
child: Row(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Icon(
Icons.ac_unit,
color: Colors.blue,
size: 10.0,
),
Text('Word\'e Dönüştür',
textAlign: TextAlign.center,
style:
TextStyle(fontSize: 18, color: Colors.white)),
],
)),
Container(
margin: const EdgeInsets.only(bottom: 20),
child: Row(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Image.asset('assets/images/prohibited.png', scale: 3),
Text('Reklam YOK',
textAlign: TextAlign.center,
style:
TextStyle(fontSize: 18, color: Colors.white)),
],
))
],
)),
This how it looks:
This is how i want it to look like:


Just replace mainAxisAlignment.center to mainAxisAlignment.start for the rows.
...
child: Row(
mainAxisAlignment: MainAxisAlignment.start,
children: [...


Replace mainAxisAlignment.center with mainAxisAlignment: MainAxisAlignment.start, on Row.
Container(
margin: const EdgeInsets.all(20),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
SizedBox(
height: 58,
),
Container(
margin: const EdgeInsets.only(bottom: 20),
child: Row(
mainAxisAlignment: MainAxisAlignment.start,
children: [
Image.asset('assets/images/foldertree.png', scale: 3),
// Icon(Icons.ac_unit),
Text('Sınırsız belge',
textAlign: TextAlign.center,
style: TextStyle(fontSize: 18, color: Colors.white)),
],
)),
Container(
margin: const EdgeInsets.only(bottom: 20),
child: Row(
mainAxisAlignment: MainAxisAlignment.start,
children: [
Image.asset('assets/images/t.png', scale: 3),
// Icon(Icons.ac_unit),
Text('Metin Algılama (OCR)',
textAlign: TextAlign.center,
style: TextStyle(fontSize: 18, color: Colors.white)),
],
)),
Container(
margin: const EdgeInsets.only(bottom: 20),
child: Row(
mainAxisAlignment: MainAxisAlignment.start,
children: [
Icon(
Icons.ac_unit,
color: Colors.blue,
size: 10.0,
),
Text('Word\'e Dönüştür',
textAlign: TextAlign.center,
style: TextStyle(fontSize: 18, color: Colors.white)),
],
),
),
Container(
margin: const EdgeInsets.only(bottom: 20),
child: Row(
mainAxisAlignment: MainAxisAlignment.start,
children: [
Image.asset('assets/images/prohibited.png', scale: 3),
// Icon(Icons.ac_unit),
Text('Reklam YOK',
textAlign: TextAlign.center,
style: TextStyle(fontSize: 18, color: Colors.white)),
],
),
)
],

Align children to top of row in Flutter?

In your Row, set crossAxisAlignment: CrossAxisAlignment.start. This will cause the Row's children to be aligned at the top of the row.

Flutter - cannot use Flexible inside Padding for text wrapping purpose

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...

That my approach to what you need:

set data inside row and column in flutter

i need to set data like this
i have tried taken row first then column then again row, but in row i am unable to set space between job id and 011.
Row(
mainAxisSize: MainAxisSize.max,
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
new Container(
margin: EdgeInsets.only(right: 10.0),
width: 50.0,
height: 50.0,
decoration: new BoxDecoration(
shape: BoxShape.circle,
image: new DecorationImage(
fit: BoxFit.fill,
image: AssetImage('assets/noimage.jpg'),
))),
Column(
mainAxisSize: MainAxisSize.max,
crossAxisAlignment: CrossAxisAlignment.start,
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: <Widget>[
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: <Widget>[
Text('Job id',
style: TextStyle(
color: Colors.grey.shade700,
fontSize: 16.0,
fontWeight: FontWeight.normal)),
Text('011',
style: TextStyle(
color: Colors.grey.shade700,
fontSize: 16.0,
fontWeight: FontWeight.normal)),
],
),
],
),
],
),
set space between job id and it's data but in my case it will jobid011 .

Try like this :
Row(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Padding(padding: EdgeInsets.only(left: 10.0),),
Container(
margin: EdgeInsets.only(right: 10.0),
width: 50.0,
height: 50.0,
color: Colors.red
),
Expanded(
child: Column(
children: <Widget>[
Row(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: <Widget>[
Text('Job id',
style: TextStyle(
color: Colors.grey.shade700,
fontSize: 16.0,
fontWeight: FontWeight.normal)),
Text('011',
style: TextStyle(
color: Colors.grey.shade700,
fontSize: 16.0,
fontWeight: FontWeight.normal)),
],
)
],
),
),
Padding(padding: EdgeInsets.only(right: 10.0),)
],
),

You can use Spacer() Widget to make this work
Row(
mainAxisSize: MainAxisSize.max,
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
new Container(
margin: EdgeInsets.only(right: 10.0),
width: 50.0,
height: 50.0,
decoration: new BoxDecoration(
shape: BoxShape.circle,
image: new DecorationImage(
fit: BoxFit.fill,

You can use crossAxisAlignment: CrossAxisAlignment.start for space between Text Widget
Row(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Expanded(
child: Text(heading,
style: AppTheme.textStyleWith(15, Colors.black)
.copyWith(fontWeight: FontWeight.bold)),
),
Expanded(
child: Text(
details,
style: AppTheme.textStyleWith(15, Colors.black),
),
)
],
);

Flutter align widget to centre and another to the right - impossible

I'm trying to do something which should be extremely simple but can't see how it is done.
I need to align the large text to the centre and the buttons to the right so it looks like image below:
With the code below the widgets are aligned left and right:
Container(
width: 300,
height: 200,
decoration: BoxDecoration(
border: Border.all(color: Colour.darkBlue, width: 2),
borderRadius: BorderRadius.all(Radius.elliptical(100, 60)),
),
child: Row(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Container(),
Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Text('Centred', style: TextStyle(fontSize: 32)),
Text('24.6 %', style: TextStyle(fontSize: 48)),
],
),
Container(
margin: EdgeInsets.only(left: 10),
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Text('BtnA', style: TextStyle(fontSize: 18)),
Text('BtnB', style: TextStyle(fontSize: 18)),
Text('BtnC', style: TextStyle(fontSize: 18)),
],
),
),
],
),
),
I tried the following method:
Container(
width: 300,
height: 200,
decoration: BoxDecoration(
border: Border.all(color: Colour.darkBlue, width: 2),
borderRadius: BorderRadius.all(Radius.elliptical(100, 60)),
),
child: Row(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Expanded(child: Container()),
Expanded(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Text('Centred', style: TextStyle(fontSize: 32)),
Text('24.6 %', style: TextStyle(fontSize: 48)),
],
),
),
Expanded(
child: Container(
margin: EdgeInsets.only(left: 10),
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Text('BtnA', style: TextStyle(fontSize: 18)),
Text('BtnB', style: TextStyle(fontSize: 18)),
Text('BtnC', style: TextStyle(fontSize: 18)),
],
),
),
),
],
),
),
But it resulted in this:
Not sure how or whether it can be done without manually setting a width for the container on the left which is clearly a far from ideal method. Flutter seems to desperately need float:right...

You was almost there. Just "Expanded" in the middle should be removed:
Container(
width: 300,
height: 200,
decoration: BoxDecoration(
border: Border.all(color: Colors.blueAccent, width: 2),
borderRadius: BorderRadius.all(Radius.elliptical(100, 60)),
),
child: Row(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Expanded(child: Container()),
Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Text('Centred', style: TextStyle(fontSize: 32)),
Text('24.6 %', style: TextStyle(fontSize: 48)),
],
),
Expanded(
child: Container(
margin: EdgeInsets.only(left: 10),
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Text('BtnA', style: TextStyle(fontSize: 18)),
Text('BtnB', style: TextStyle(fontSize: 18)),
Text('BtnC', style: TextStyle(fontSize: 18)),
],
),
),
),
],
),
),

Try with ListTile Widget, I have made changes using ListTile, please check if it works for you
Center(
child: Container(
alignment: Alignment.center,
margin: EdgeInsets.only(top: 10),
padding: EdgeInsets.all(15),
width: 300,
height: 150,
decoration: BoxDecoration(
border: Border.all(color: Colors.blue, width: 2),
borderRadius: BorderRadius.all(Radius.elliptical(100, 60)),
),
child: ListTile(
title: Text('Centred',
textAlign: TextAlign.center, style: TextStyle(fontSize: 30)),
subtitle: Text('24.6 %',
textAlign: TextAlign.center, style: TextStyle(fontSize: 48)),
trailing: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Text('BtnA', style: TextStyle(fontSize: 15)),
Text('BtnB', style: TextStyle(fontSize: 15)),
Text('BtnC', style: TextStyle(fontSize: 15)),
],
),
),
),
)

child: Center(
child: Container(
width: 300,

decoration: BoxDecoration(

Flexible(

Align(

How to position these icons in Flutter?

Is there anyone, who can help me?

I made a some changes. Now these icons are same height as text height, I hope works for you
#override
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: Colors.white,
body: SafeArea(
child: Container(
padding: EdgeInsets.all(16.0),
child: Column(
children: [
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
Row(
children: [Icon(Icons.arrow_back)],
),
Row(
children: [
Icon(Icons.archive),
SizedBox(width: 5.0),
Icon(Icons.delete),
SizedBox(width: 5.0),
Icon(Icons.mail),
SizedBox(width: 5.0),
Icon(Icons.more_vert)
],
)
],
),
SizedBox(height: 16.0),
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
Row(
children: [
Text('Voucher',
style:
TextStyle(color: Colors.black, fontSize: 18.0)),
SizedBox(width: 8.0),
Container(
color: Colors.grey[200],
child: Padding(
padding: EdgeInsets.fromLTRB(4, 2, 4, 2),
child: Text(
'Odebrane',
style:
TextStyle(color: Colors.black, fontSize: 12.0),
),
),
)
],
),
Row(
children: [Icon(Icons.star_border)],
)
],
),
SizedBox(height: 16.0),
Container(
child: Row(
mainAxisSize: MainAxisSize.max,
mainAxisAlignment: MainAxisAlignment.start,
children: <Widget>[
Container(
height: 45.0,
width: 45.0,
decoration: BoxDecoration(
color: Colors.blue[100], shape: BoxShape.circle),
child: Center(
child: Text(
'M',
style: TextStyle(fontSize: 20.0),
),
)),
SizedBox(
width: 16,
),
Expanded(
child: Container(
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Container(
child: Row(
mainAxisAlignment:
MainAxisAlignment.spaceBetween,
children: <Widget>[
Container(
child: Row(
children: <Widget>[
Text('McDonalds Poland',
style:
TextStyle(color: Colors.black)),
SizedBox(width: 8.0),
Text('Wczoraj',
style:
TextStyle(color: Colors.grey)),
],
),
),
Container(
child: Row(
children: <Widget>[
Icon(Icons.reply),
Icon(Icons.more_vert)
],
),
)
],
),
),
Container(
child: Row(
children: [
Text('do mnie',
style: TextStyle(color: Colors.grey)),
Icon(Icons.expand_more)
],
),
)
],
),
),
),
],
),
),
],
),
),
),
);
}

this is work! You have to put the 'M' Container inside the Row and put the icons inside a Container
return Scaffold(
body: Container(
padding: EdgeInsets.only(top: 50),
child: new Column(
mainAxisAlignment: MainAxisAlignment.start,
crossAxisAlignment: CrossAxisAlignment.center,
children: <Widget>[
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
crossAxisAlignment: CrossAxisAlignment.end,
children: [
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
crossAxisAlignment: CrossAxisAlignment.end,
children: [
Container(
height: 45.0,
width: 45.0,
decoration: BoxDecoration(
color: Colors.blue[100], shape: BoxShape.circle),
child: Center(
child: Text(
'M',
style: TextStyle(fontSize: 20.0),
),
)),
Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Row(
children: [
Text('McDonalds Poland',
style: TextStyle(color: Colors.black)),
SizedBox(width: 8.0),
Text('Wczoraj',
style: TextStyle(color: Colors.grey))
],
),
Row(
children: [
Text('do mnie',
style: TextStyle(color: Colors.grey)),
Icon(Icons.expand_more)
],
)
],
),
],
),
Container(
padding: EdgeInsets.only(top: 50),
child: Row(
children: [
Icon(Icons.reply),
Icon(Icons.more_vert)
],
),
)
],
)
])),
);
