I am developing a multi language application supports Locale('en') (English) and Locale('ar') (Arabic) , I have a Row() with four children :
Row(
children: [
Flexible(
child: Container(
padding: const EdgeInsets.all(20),
margin: const EdgeInsets.all(10),
child: Text(
"1",
style: TextStyle(color: Colors.white),
),
color: Colors.blue,
),
),
Flexible(
child: Container(
padding: const EdgeInsets.all(20),
margin: const EdgeInsets.all(10),
child: Text(
"2",
style: TextStyle(color: Colors.white),
),
color: Colors.blue,
),
),
Flexible(
child: Container(
padding: const EdgeInsets.all(20),
margin: const EdgeInsets.all(10),
child: Text(
"3",
style: TextStyle(color: Colors.white),
),
color: Colors.blue,
),
),
Flexible(
child: Container(
padding: const EdgeInsets.all(20),
margin: const EdgeInsets.all(10),
child: Text(
"4",
style: TextStyle(color: Colors.white),
),
color: Colors.blue,
),
),
],
)
when the locale is Locale('en') children laid out left to right :
and when the locale is Locale('ar') children laid out right to left :
Problem is I need children in this Row() specifically to be laid left to right regardless the current locale , is there any way to achieve this rather than build different widget based on the current locale ?
if(Localizations.localeOf(context).languageCode == 'en'){
// build some widget
}else{
// build different widget
}
Solved by setting the textDirection property on Row() widget to TextDirection.ltr which determines the order to lay children out horizontally and how to interpret start and end in the horizontal direction.

I want to align the text "2022" on the bottom of the screen while keeping the image and its neighbor text at the center of the screen.
class SplashScreen extends StatelessWidget {
const SplashScreen({Key? key}) : super(key: key);
#override
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: Globalcolors.mainColor,
body: Container(
padding: const EdgeInsets.all(10),
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Center(
child: Image.asset(
'assets/images/splash_logo.png',
color: Colors.white,
),
),
const Padding(
padding: EdgeInsets.all(50),
child: Text(
'Sample Text',
style: TextStyle(
color: Colors.white,
fontSize: 36,
fontFamily: 'MouseMemoirs'),
),
),
const Text(
'2022',
style: TextStyle(color: Colors.white, fontSize: 12),
),
],
),
),
);
}
}
I tried to use this link to solve the problem. I used Expanded:
const Expanded(
child: Align(
alignment: FractionalOffset.bottomCenter,
child: Text(
'2022',
style: TextStyle(color: Colors.white, fontSize: 12),
),
),
)
But, The result is not good:
You can user Stack and column widgets like
Stack(
children: [
Column(), // contains the image and title
Align(
alignment: Alignment.bottomCenter,
child: Text("2022"),
),
]
)
You can also use Positioned widget to align the text 2022
you can use the bottom method that comes with the scaffold
Scaffold(
bottom : Text("2020")
)
this will make the text always on the bottom of the screen
Need help. I want to put the text Want to get your money? and TextButton Redeem under button 611 (screenshot below) removing all padding. I have already tried many methods, but in the end it did not work out to place the widget under the button itself. Through the Flutter Inspector, you can see that there is still a distance at the top, but I don’t understand how to put it there. I will be grateful for help.
body
Padding(
padding: const EdgeInsets.symmetric(horizontal: 24),
child: Column(
children: [
const SizedBox(height: 24),
const TotalCoinsWidget(
coins: '611',
),
const RedeemButton(
textStyle: constants.Styles.smallBookTextStyleWhite,
buttonStyle: constants.Styles.smallMediumTextStyleWhite),
Padding(
padding: EdgeInsets.only(bottom: 50),
child: Text('Hello'),
)
],
),
);
textbutton
Widget build(BuildContext context) => Row(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Text('Want to get your money?', style: textStyle),
TextButton(
style: TextButton.styleFrom(
padding: EdgeInsets.zero,
minimumSize: Size.zero,
),
onPressed: () {},
child: Text(
'Redeem',
style: buttonStyle,
),
),
],
);
TotalCoinsWidget
Widget build(BuildContext context) => Container(
alignment: Alignment.center,
width: _width,
height: _height,
decoration: BoxDecoration(
color: color,
borderRadius: BorderRadius.circular(25),
boxShadow: [
BoxShadow(
color: color.withOpacity(0.5),
blurRadius: _blurRadius,
offset: Offset(_xOffset, _yOffset)),
],
),
child: Text(
coins,
style: textStyle,
),
);
you are using TextButton widget, and if you check out the property style: TextButton.styleFrom(), you will find a property called tapTargetSize, by default tapTargetSize property uses MaterialTapTargetSize.padded, and to fix your problem you must assign tapTargetSize property to MaterialTapTargetSize.shrinkWrap to shrinks the tap target size to the minimum size.
tapTargetSize: MaterialTapTargetSize.shrinkWrap
is not sufficient. Just add
padding: EdgeInsets.zero
In appBar I have a container which is responsible for displaying text (it could be 5 chars or even 100). And I want to adjust width of container based on text. For example for 5 chars container should show text and should be a little bigger than text (I will add paddings later), but for 100 chars container should take all possible space and show text with dots.
Currently I have two solutions:
The first one (Without spacer() in tree) is expanding container always to the biggest possible width (like I said, I don't need this big container for short texts)
The second one (with spacer() in tree) is always displaying container with 1/3 width of appbar (Did someone know why it's always the same width? It's kind of interesting).
return Scaffold(
appBar: AppBar(
titleSpacing: 10,
centerTitle: false,
automaticallyImplyLeading: false,
title: SizedBox(
width: MediaQuery.of(context).size.width,
child: Row(
crossAxisAlignment: CrossAxisAlignment.center,
children: <Widget>[
Container(height: 40, width: 40, color: Colors.amberAccent),
const SizedBox(width: 10),
const Text("Some Text"),
const SizedBox(width: 10),
Expanded(
child: Container(
color: Colors.purpleAccent,
height: 40,
child: const Center(
child: Text(
"text",
overflow: TextOverflow.ellipsis,
softWrap: true,
),
),
),
),
],
),
),
),
body: Container(),
);
So, how can I adjust width of this container to text inside?
Update:
I don't know if I explained it correctly, because your answers weren't related with my question 😁 So I will try again:
I want the last one container to take full possible width if text is long and for shorten texts just width to cover background behind text.
Here is long text: (It should be like that)
Here is short text: (Container should be smaller)
You should use constraints: BoxConstraints(maxWidth:), property of Container.
Please go with below code.
Container(
color: Colors.red,
padding: const EdgeInsets.all(20.0),
constraints: BoxConstraints(
maxWidth: MediaQuery.of(context).size.width * 0.7,
),
child: Text('Hello', style: TextStyle(color: Colors.black)),
),
Spacer(),
Flexible(
child: Container(
color: Colors.purpleAccent,
height: 40,
child: const Center(
child: Text(
"Long Textttttttttttttttttttt",
overflow: TextOverflow.ellipsis,
softWrap: true,
),
),
),
),
Your result will be like below screenshot.
I implement another text for checking dynamic width of container.
Container(
color: Colors.red,
padding: const EdgeInsets.all(20.0),
constraints: BoxConstraints(
maxWidth: MediaQuery.of(context).size.width * 0.7,
),
child: Text('Hello World', style: TextStyle(color: Colors.black)),
),
Spacer(),
Flexible(
child: Container(
color: Colors.purpleAccent,
height: 40,
child: const Center(
child: Text(
"Long Textttttttttttttttttttt",
overflow: TextOverflow.ellipsis,
softWrap: true,
),
),
),
),
For This You can Use :
Flexible Widget:
Example:
Flexible(
child: Container(
color: Colors.green,
)
),
or Wrap Widget :
Example :
Card(
margin: const EdgeInsets.only(top: 20.0),
child: Padding(
padding: const EdgeInsets.all(20.0),
child: Column(
children: <Widget>[
Text(
'Categories',
style: TextStyle(fontFamily: 'MonteSerrat', fontSize: 16.0),
),
Wrap(
children: <Widget>[
_checkBox('Gaming'),
_checkBox('Sports'),
_checkBox('Casual'),
_checkBox('21 +'),
_checkBox('Adult'),
_checkBox('Food'),
_checkBox('Club'),
_checkBox('Activities'),
_checkBox('Shopping')
],
)
],
),
));
I am writing a widget in flutter for a project which should look like this, I am new to flutter and I am trying to imitate the card below
So far this is my code for the widget
import 'package:flutter/material.dart';
import 'package:smooth_star_rating/smooth_star_rating.dart';
class TrailCard extends StatelessWidget {
const TrailCard({Key key}) : super(key: key);
#override
Widget build(BuildContext context) {
return Padding(
padding: const EdgeInsets.all(8.0),
child: Card(
shape:
RoundedRectangleBorder(borderRadius: BorderRadius.circular(20)),
child: InkWell(
onTap: () {},
child: Padding(
padding: const EdgeInsets.all(16.0),
child: Row(
crossAxisAlignment: CrossAxisAlignment.center,
children: [
ClipRRect(
borderRadius: BorderRadius.circular(20.0),
child: Image.asset(
'assets/images/cocoa.jpg',
height: 100,
width: 90,
fit: BoxFit.fitHeight,
),
),
Padding(
padding: const EdgeInsets.all(8.0),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Text(
"Boring Cocoa",
style: TextStyle(
fontSize: 18, fontWeight: FontWeight.bold),
),
Text('Rajhamundry, AP'),
Text(
'Feel the authentic flavours of life while you visit the farms around Rajahmundry',
overflow: TextOverflow.ellipsis,
)
],
),
),
],
)),
)),
);
}
}
I tried using flexible and expanded to try and make the content look the way but I am getting overflow error
You can wrap the Padding widget with a Flexible widget so it takes only the amount of space needed:
NOTE: you should also set the maximum amount of lines the Text widget should take before showing the ellipsis.
Flexible(
// new line
child: Padding(
padding: const EdgeInsets.all(8.0),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Text(
"Boring Cocoa",
style: TextStyle(fontSize: 18, fontWeight: FontWeight.bold),
),
Text('Rajhamundry, AP'),
Text(
'Feel the authentic flavours of life while you visit the farms around Rajahmundry more text to cause overflow',
// set maximum number of lines the text should take
maxLines: 3, // new line
overflow: TextOverflow.ellipsis,
)
],
),
),
);
RESULT:
Wrap Padding with Expanded
Expanded(
child: Padding(
padding: const EdgeInsets.all(8.0),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Text(
"Boring Cocoa",
style: TextStyle(
fontSize: 18, fontWeight: FontWeight.bold),
),
Text('Rajhamundry, AP'),
Text(
'Feel the authentic flavours of life while you visit the farms around Rajahmundry',
overflow: TextOverflow.ellipsis,
)
],
),
),
)
What I want to achieve is to have a text widget inside a Column of fixed height. When the text is long I want the overflow property which is set to TextOverflow.ellipsis to kick in. The Text widget has its maxLines property set to a high value to allow it to wrap down. But there are other widgets in the column too, both before and after the text widget. The text widget is in an Expanded widget so that it takes up as much room in the column. Full code is pasted below.
The problem with this setup is that the text is overflowing its container parent. I have a border decoration on the container that shows this happening. Why is this happening and how do I fix it.
import 'package:flutter/material.dart';
void main() {
runApp(App());
}
class App extends StatelessWidget {
#override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
appBar: AppBar(
title: Text("Overflow"),
),
body: Center(
child: Container(
width: 200.0,
height: 250.0,
child: Card(
child: Column(children: <Widget>[
Image.asset(
"assets/bereket.jpg",
width: double.infinity,
fit: BoxFit.cover,
),
Expanded(
child: Container(
padding: EdgeInsets.all(8.0),
child: (Column(
children: [
Text(
"በረከት ስምኦን፡ «ወይዘሮ አና ጎሜዝ፤ እርስዎ አያገባዎትም! አርፈው ይቀመጡ በልልኝ»",
maxLines: 2,
style: Theme.of(context)
.primaryTextTheme
.subhead
.copyWith(
color: Colors.black,
),
overflow: TextOverflow.ellipsis),
Expanded(
child: Container(
decoration: BoxDecoration(
border: Border.all(
color: Colors.green, width: 2.0),
),
child: Text(
"""ባለፉት ሁለት አስርት ዓመታት በኢትዮጵያ ፖለቲካ ከፍተኛ ተጽእኖ ፈጣሪ የነበሩት አቶ በረከት ስምኦን በቅርቡ ከብአዴን ማእከላዊ ኮሚቴ አባልነት መታገዳቸው ይታወሳል።

maxLines: 10,
style: Theme.of(context)
.primaryTextTheme
.caption
.copyWith(color: Colors.black),
overflow: TextOverflow.ellipsis,
))),
Row(
crossAxisAlignment: CrossAxisAlignment.center,
children: <Widget>[
Container(
width: 20.0,
height: 20.0,
child: Image.asset("assets/bbc.png"),
),
SizedBox(width: 8.0),
Text('ቢቢሲ - ከሁለት ሰአት በፊት',
style: Theme.of(context)
.textTheme
.caption
.copyWith(fontSize: 10.0))
],
)
],
))))
]))),
),
),
);
}
}
Try wrapping your column with 'Flexible' instead of expandable.
I had the same issue with text overflowing in column and wrapping column itself with 'flexible' allowed to make text smaller.
Flexible(
child: Padding(
padding: const EdgeInsets.only(left: 8.0),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Padding(
padding: const EdgeInsets.only(bottom: 8.0),
child: Text(
'Name',
style: CustomTextStyle.blueTitle14(context),
),
),
Padding(
padding: const EdgeInsets.only(bottom: 4.0),
child: Text('Long text'),
),
],
),
),
),
Based on my experiences, you should assign a fixed width to the Container containing the overflowing text, as per this post. Flutter- wrapping text .
In present version of flutter (presently 3.0) you dont have to use Flexible or Expanded as Column's child automatically expandes to fill the content of child .
For ellipses define the maxLine attribute.
Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: const [
Text(
"This is very very very very very very very very very very very very very very very very very long text in Row 1 of Column",
maxLines: 2,
style: TextStyle(
backgroundColor: Colors.green, overflow: TextOverflow.ellipsis),
),
Text("This is very very long text in Row 2 of Column",
style: TextStyle(
overflow: TextOverflow.ellipsis,
backgroundColor: Colors.yellow))
],
)
