I try to fit my Cloum child of the expantion Card into his expanded Container. It always overflow his Card perent.
I tried a few things like putting the container in a FittedBox but nothing is working. So my goal is to make the column alway fitting in the expanded part of the card, or that the Card expand more if there are to many children in the Column. Can anybuddy tell me this magic trick? Thanks a lot !
enter image description here
ExpansionCard(
leading: CircleAvatar(
child: Text('1000'),
backgroundColor: Colors.black,
),
borderRadius: 20,
background: Image.asset(
"assets/images/unnamed.jpg",
fit: BoxFit.cover,
),
title: Container(
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Text("Freefly Sprung mit Carlo ",
style: jumpCardHeaderStyle),
Text(
DateFormat.yMMMd().format(DateTime.now()),
style: jumpCardDateStyle,
),
],
),
),
children: <Widget>[
FittedBox(
child: Container(
margin: EdgeInsets.symmetric(horizontal: 7),
child: Padding(
padding: const EdgeInsets.all(8.0),
child: Column(
mainAxisAlignment: MainAxisAlignment.spaceAround,
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Text("Exit Alt. : 4000m", style: kJumpTextStyle),
Divider(),
Text("Dpl. Alt. 1000m", style: kJumpTextStyle),
Divider(),
Text("Time FF 42sec", style: kJumpTextStyle),
Text("AVG.Speed T 127MPH", style: kJumpTextStyle),
Text("AVG.Speed T 127MPH", style: kJumpTextStyle),
],
),
),
),
)
],
),
Have you tried to use a card that has a Wrap object as a child? This should allow you to contain everything you need
Card(
child: Wrap(
children: []
))

here is the UI that I'm trying to build
but this is the output
I tried alignment also , but that also didn't working
but when setting a fixed height this is working fine
but I can't fill this using the fit parameter,
here is the code
Scaffold(
backgroundColor: kDarkTheme,
body: SafeArea(
child: Column(
children: [
const SizedBox(height: 10),
Row(
//code for top button
),
const SizedBox(height: 150),
Stack(
children: [
Center(
child: CircleAvatar(
radius: radiusSize + 5,
backgroundColor: kDarkCounterColor,
child: CircleAvatar(
backgroundColor: kDarkTheme,
radius: radiusSize,
),
),
),
Center(
child: Padding(
padding: const EdgeInsets.only(top: 35),
child: Text(
'39',
style: GoogleFonts.italiana(
fontSize: 120, color: kDarkCounterColor),
),
),
),
],
),
const SizedBox(height: 15),
const Text(
'Tap To Count',
style: TextStyle(
fontFamily: 'Helvatica',
color: Color(0xff656158),
),
),
Expanded(
child: Align(
alignment: Alignment.bottomRight,
child: SvgPicture.asset(
kDarkThemeImage,
)),
)
],
),
))
this is the code
then the first error appears again. how could I fix this?
You are using the Expanded widget on a column that doesn't have a set size. Try adding MainAxisSize attribute to your column, like this:
Column(
mainAxisSize: MainAxisSize.max, // Add this like
children: [
...
This will make your column fit the whole available size on the previous widget (a scaffold for the whole screen). Then the expanded widget will fill the remaining space not used by the other widgets inside the column.
I'm having issues with the layout because of the long text, I've tried using Expanded / Flexible with the text that is causing the issue to fill the space it needs but it's overflowing. I know the question is asked hundred times, but I don't understand where is the mistake. I tried applying to both Expanded / Flexible to all of the Row/Columns individually and too all at the same time (mostly I was trying out layouts to try to fix it), and I still have the issue... I even tried to use the FittedBox with fit: BoxFit.(all of them).
Container(
alignment: Alignment.centerLeft,
child: Column(
children: [
Row(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Padding(
padding: const EdgeInsets.only(right: 8.0),
child: Icon(Icons.directions_car),
),
Row(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Text("Text 1"),
SizedBox(
height: 4,
),
Text('TEXT 2'),
],
),
SizedBox(
width: 27,
),
Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Text('1 World Way, Los Angeles, CA 90045, USA',
textAlign: TextAlign.left,
),
SizedBox(
height: 4,
),
Text('FLIGHT 3231'),
],
),
],
),
],
),
],
),
);
By my understanding, and do correct me if I'm wrong, applying Expanded / Flexible, Flexible takes only the needed space, and Expanded takes all available space, respecting the flex factor. So most of the time I use the Flexible widget, but this time it is not working.
Thanks in advance for the help!
Try using Expanded widget with flex value set as per the expectation of UI filling.
Sample Code:
Center(
child: Container(
height: 80,
color: Colors.yellow,
child: Row(
mainAxisAlignment: MainAxisAlignment.start,
children: [
Padding(
padding: const EdgeInsets.all(8.0),
child: Icon(Icons.bus_alert),
),
Expanded(
flex: 1,
child: Container(
width: 1,
color: Colors.green,
child: Column(
children: [Text("Text 1"), Text("Text 1")],
),
)),
Expanded(
flex: 3,
child: Container(
color: Colors.blue,
child: Column(
mainAxisAlignment: MainAxisAlignment.spaceAround,
children: [
Text("1 World Way, Los Angeles, CA 90045, USA"),
Text("FLIGHT 3231"),
],
),
))
],
),
))
Note: There is a limitation for the text content using. We need to make sure to set the height according to the expected text length.
You can use Flexible or Expanded Widget You should try to below code :
Card(
shape: RoundedRectangleBorder(
side: BorderSide(
color: Colors.blue,
),
borderRadius: BorderRadius.circular(15.0),
),
margin: EdgeInsets.all(16.0),
child: Container(
padding: EdgeInsets.all(8.0),
alignment: Alignment.centerLeft,
child: Column(
children: [
Row(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Icon(Icons.directions_car),
SizedBox(
width: 10,
),
Flexible(
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Text("Text 1"),
SizedBox(
height: 4,
),
Text('TEXT 2'),
],
),
),
SizedBox(
width: 27,
),
Flexible(
child: Container(
child: Column(
children: [
Text(
'1 World Way, Los Angeles, CA 90045, USA',
textAlign: TextAlign.left,
),
SizedBox(
height: 4,
),
Text(
'FLIGHT 3231',
textAlign: TextAlign.left,
),
],
),
),
),
],
),
],
),
),
),
Your screen like this :
wrap it by a container with fixed width and then use auto_sized_text. Or you can wrap your Text widget by FittedBox by fixed width. it would do the same approach. Feel free to add maxLine, minFontSize and maxFontSize' in auto_sized_text. Using ExpandedorFlexible` only affects the size of the container when your text length is lower than the given width, and It does not help you in this situation.
If the text is really long, then using Expanded will wrap the text according to the parent widget, thus leading to change in the font size. You might consider using ellipsis.
return Container(
width:300 //give a width of your choice
child: Text('Any long text',
overflow:TextOverflow.ellipsis,
),
);
I am trying to display some children inside a column, they are properties of an object. However, one of the properties sometimes has a null value, so I want to make a validation. If the value of this property is null, I don't want to display anything. The answer it's not as easy as saying "just use a ternary operator and put an empty Container() instead". The container takes up space even if it is almost imperceptible. The same happens with Visibility. Empty Text, works the same. And so on. Here is my code:
Container(
height: heightOfContext,
child: Row(
mainAxisAlignment: MainAxisAlignment.start,
children: [
Padding(
padding: const EdgeInsets.all(5.0),
child: ClipRRect(
borderRadius: BorderRadius.circular(10),
child: FittedBox(
fit: BoxFit.fill,
child: FadeInImage(
placeholder: AssetImage(
"assets/images/loading.png"),
image: NetworkImage(
products[index].file_url),
),
),
),
),
///HERE IS THE ISSUE, AT THE LAST CHILD
Expanded(
child: Center(
child: Column(
crossAxisAlignment: CrossAxisAlignment.center,
mainAxisAlignment:
MainAxisAlignment.spaceEvenly,
children: [
Text(
'Modelo: ${products[index].description}',
style: TextStyle(
fontWeight: FontWeight.bold),
),
Text(
'Producto: ${products[index].colorName}'),
Text(
'Color: ${products[index].price}'),
Text(
'Categoría: ${products[index].categoryName}'),
productsSearchList[index].catalogue != null
? Text(
'Catálogo: ${products[index].catalogue}')
: Container(),
],
),
),
),
],
),
),
There are 2 options to fix this:
Did you try SizedBox.shrink or Container(height: 0, width: 0)?
The easiest way is to use an if statement within the column:
Column(
crossAxisAlignment: CrossAxisAlignment.center,
mainAxisAlignment:
MainAxisAlignment.spaceEvenly,
children: [
Text(
'Modelo: ${products[index].description}',
style: TextStyle(
fontWeight: FontWeight.bold),
),
Text(
'Producto: ${products[index].colorName}'),
Text(
'Color: ${products[index].price}'),
Text(
'Categoría: ${products[index].categoryName}'),
if(productsSearchList[index].catalogue != null) Text(
'Catálogo: ${products[index].catalogue}')
],
),
You can define a boolean variable mean
If data fetched correctly set that variable true and show your container if not ,means that variable is false then dont show the container.(with ?: operators)
I've been toying with lists in flutter, and everything is fine. I'm starting to understand the logic of the whole thing.
Now I wanted to do a simple layout like that :
My problem is that I can't find a way to make the first row. I tried to tell Row to let its two children take half and no less no more, but I didn't really find a way. (The inside thing will eventually be buttons.)I tried several things to no avail. Here is the layout I started from :
Widget build(BuildContext context) {
return Scaffold(
body: Center(
child: Column(children: <Widget>[
Padding(
padding: EdgeInsets.only(top: 50.0),
),
Row(
children: <Widget>[
Padding(
padding: EdgeInsets.only(
top: buttonPaddingTop,
left: buttonPaddingSide,
right: buttonPaddingSide),
child: ButtonTheme(
child: FlatButton(
onPressed: () {},
color: Colors.grey,
child: const Text('LARGE TEXT',
overflow: TextOverflow.ellipsis,
style: TextStyle(fontSize: buttonFontSize)),
),
),
),
Padding(
padding: EdgeInsets.only(
top: buttonPaddingTop,
left: buttonPaddingSide,
right: buttonPaddingSide),
child: ButtonTheme(
child: FlatButton(
onPressed: () {},
color: Colors.grey,
child: const Text('LARGE TEXT',
overflow: TextOverflow.ellipsis,
style: TextStyle(fontSize: buttonFontSize)),
),
),
),
],
),
]),
),
);
}
Should I continue trying like this, or should I try another object than Row to arrange the layout ?
Expanded takes as much space as available in this case horizontally. That means if you would use 2 Expanded widgets inside your Row, the space will be divided by half.
Try this:
Column(
children: <Widget>[
Row(
children: <Widget>[
Expanded(
child: Text('first half'),
),
Expanded(
child: Text('second half'),
),
],
),
Row(
children: <Widget>[
Expanded(
child: Text('first half'),
),
Expanded(
child: Text('second half'),
),
],
),
Row(
children: <Widget>[
Expanded(
child: Text('full width'),
)
],
),
],
)
Make sure you read more about Flutter widgets, for example watch this video (and other ones in this series):

I have a row in Flutter with two widgets. I'm trying to keep the first widget centered in the middle of the screen and the second widget forced to the far right of the screen.
I've tried using Spacer(). This results in the app returning a blank screen.
I've also tried using Expanded. This sends the second widget off the screen completely.
Trying mainAxisAlignment: MainAxisAlignment.spaceBetween did not seem to have any effect.
#override
Widget build(BuildContext context) {
return new Container(
height: MediaQuery.of(context).size.height,
child: SingleChildScrollView(
child: new Column(
crossAxisAlignment: CrossAxisAlignment.center,
mainAxisSize: MainAxisSize.max,
children: <Widget>[
new Container(
child: new GestureDetector(
onTap: () {
FocusScope.of(context).requestFocus(new FocusNode());
},
child: Column(
children: <Widget>[
SizedBox(height: 40.0),
Row(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
new Column(
children: <Widget>[
new Container(
child: Row(
mainAxisAlignment:MainAxisAlignment.spaceBetween,
children: <Widget>[
Container(),
Container(
child: Text(
'Profile',
textAlign: TextAlign.center,
style: TextStyle(
fontFamily: 'Lato',
color: Colors.white,
fontSize: 50.0,
fontWeight: FontWeight.w700,
),
),
),
Container(
child: IconButton(
icon: Icon(
Icons.settings,
color: Colors.white,
size: 30.0,
),
onPressed: () {
Navigator.push(
context,
MaterialPageRoute(
builder: (context) => OnBoarding()),
);
}),
),
]),
),
),
],
),
],
),
You can use a Row with an Expanded child that contains a Stack. Centre your text with Center and position the icon with Positioned, like so:
[...]
child: Column(
children: <Widget>[
SizedBox(height: 40.0),
Row(
children: <Widget>[
Expanded(
child: Stack(
children: [
Center(
child: Text(...),
),
),
Positioned(
right: 8,
child: IconButton(...),
[...]
Simply just add Spacer() between your main text and the Icon you want to the far right.
For example:
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: <Widget>[
IconButton(
icon: Icon(Icons.arrow_back),
onPressed: () {},
),
Text(
'Random test text',
style: TextStyle(color: Colors.white),
),
Spacer(),
IconButton(
icon: Icon(Icons.more_vert_rounded),
color: Colors.white,
onPressed: () {},
),
],
)
I hope this helps you. And I hope the format of the code is readable. Still getting a hang of stackoverflow comments
I did this and worked in my project
child:Row(
**crossAxisAlignment: CrossAxisAlignment.center,
mainAxisAlignment: MainAxisAlignment.end,**
children: [
Icon(MaterialCommunityIcons.comment_outline),
Text("0"),
Icon(Icons.favorite_border),
Text("0"),
],
),
I needed align Icons and Text at right in Row widget
Container(
child: Row(
crossAxisAlignment: CrossAxisAlignment.center,
mainAxisAlignment: MainAxisAlignment.end
children: [ // put your widget list and be happy ]
)
)
enter image description here
Use a row with this following structure:
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: <Widget>[
Container(),
Container(
child: Text(
'Profile',
textAlign: TextAlign.center,
style: TextStyle(
fontFamily: 'Lato',
color: Colors.white,
fontSize: 50.0,
fontWeight: FontWeight.w700,
),
),
),
Container(
child: IconButton(
icon: Icon(
Icons.settings,
color: Colors.white,
size: 30.0,
),
),
),
]
),
what will happen is that the spaceBetween property will divide available space equally between the widgets in the row, so I put an empty Container, and this will force the Text widget to be in the middle of the row and the IconButton in the far end as you desire.
I noticed in your code snippet that you have a Column with a single Row which again contains a single Column , you should eliminate this redundancy to optimize your code and make it easier to debug:
Have you tried setting the mainAxisAlignment of the row to mainAxisAlignment.center?
Imo the easiest way to do this is to create a row with 2 children: The first child is an Expanded Row with all your "main" widgets. The second child is your widget which must be aligned to the end.
Row(
children: [
Expanded(
child: Row(
children: [...mainWidgets...],
),
),
...endWidget...
],
),
Note that Expanded is space-greedy. If you use e.g. MainAxisAlignment.center for your Expanded Row, then your children are drawn across the whole avialable width. If this is not to your liking, Id suggest to wrap the Expanded-Row (not Expanded) inside a Container with "constraints: BoxConstraints(maxWidth: 500)". Obviously Expanded shouldnt be Constrained.
Achieve using Expanded & Align like below inside Row:
Row(
mainAxisAlignment: MainAxisAlignment.start,
children: <Widget>[
...some other widgets,
Expanded(
//Expanded will help you to cover remaining space of Row
flex: 1,
child: Align(
//Align with alignment.centerRight property will move the child to righteous inside Expanded
alignment: Alignment.centerRight,
child: const Icon(Icons.arrow_back),
),
),
],
),
Note, the Expanded has to be just inside the Row children: <Widget>[],
othewise suppose you've put the GestureDetector inside Row children: <Widget>[], and inside GestureDetector you have put your Expanded, then it won't
work.
Hope this would help many one.
