Flutter: How to Split text into 2 lines - flutter

I'm using columns to display 2 texts. 1st text represents the title and 2nd text displays the quotation. I'm trying to split the quotation text into multi-lines using the max line's property, but the text is overlapping with other items. I try to use Expanded and flexible property to overcome this issue but still, I didn't get desired output. This is what I'm trying to do:
Container(
color: Color(0xff1D1D1D),
width: double.maxFinite,
height: responsivness.safeBlockVertical! * 54.55,
// Stories Title
child: Column(
children: [
Padding(
padding: const EdgeInsets.all(8.0),
child: Text("Stories",
style: Theme.of(context).textTheme.headline1!),
),
// list of Stories
Expanded(
child: ListView.builder(
itemCount: 5,
shrinkWrap: true,
scrollDirection: Axis.horizontal,
itemBuilder: (context, index) {
return Stack(
clipBehavior: Clip.none,
children: [
Padding(
padding: EdgeInsets.all(h * .014),
child: Container(
width:
responsivness.safeBlockHorizontal! *
47,
height:
responsivness.safeBlockVertical! *
17,
decoration: BoxDecoration(
borderRadius:
BorderRadius.circular(10),
color: Colors.amber,
),
),
),
Positioned(
top: h * .19,
left: h * .016,
child: Column(
mainAxisAlignment:
MainAxisAlignment.start,
crossAxisAlignment:
CrossAxisAlignment.start,
children: [
Text(
"Steve H.",
style: Theme.of(context)
.textTheme
.headline1!,
),
Text(
"I bet away my house and all the money i got",
style: Theme.of(context)
.textTheme
.bodyText2!,
maxLines: 2,
overflow: TextOverflow.ellipsis,
),
],
),
),
],
);
},
),
),
],
),
),

Try below code hope its helpful to you. I think the problem comes from Stack widget so remove your Stack and Positioned Widget, and used Column() widget instead.
Padding(
padding: const EdgeInsets.all(8.0),
child: Column(
children: [
Padding(
padding: const EdgeInsets.all(8.0),
child: Text("Stories",
style: Theme.of(context).textTheme.headline1!),
),
// list of Stories
Expanded(
child: ListView.builder(
itemCount: 5,
shrinkWrap: true,
scrollDirection: Axis.horizontal,
itemBuilder: (context, index) {
return Column(
mainAxisAlignment: MainAxisAlignment.start,
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Container(
width: 200,
height: 100,
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(10),
color: Colors.amber,
),
),
Padding(
padding: const EdgeInsets.all(8.0),
child: Column(
mainAxisAlignment: MainAxisAlignment.start,
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Text(
"Steve H.",
),
Text(
"I bet away my house and all the money i got",
style: Theme.of(context).textTheme.bodyText2!,
maxLines: 2,
overflow: TextOverflow.ellipsis,
),
],
),
),
],
);
},
),
),
],
),
),
Your result screen->

Your text is overlapping because of the Stack widget. You can either wrap your text inside a sized box to give a fix width or you can remove Stack widget and use Column instead. I dont find any particular use of stack here, so probably you can remove it without any issues.

Try wrapping with container and specify any width
Container(
width: 100,
child: Text(
"I bet away my house and all the money i got",
style: Theme.of(context).textTheme.subtitle1,
maxLines: 2,
overflow: TextOverflow.ellipsis,
),
),

Try wrapping your overlapping Text with a fixed width SizedBox, and see if it fixes your issue.

Have you tried wrapping the Text in a FittedBox()

RenderFlex children have non-zero flex but incoming width constraints are unbounded - Flutter

I'm trying to show cart items horizontally using listview builder but it is throwing up following error
RenderFlex children have non-zero flex but incoming width constraints are unbounded (When a row is in a parent that does not provide a finite width constraint, for example if it is in a horizontal scrollable, it will try to shrink-wrap its children along the horizontal axis. Setting a flex on a child (e.g. using Expanded) indicates that the child is to expand to fill the remaining space in the horizontal direction.)
I already wrapped the list view builder with defined height but still throwing up the error
Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Text('MY CART', style: GoogleFonts.oswald(color: Colors.black, fontSize: 18.0, fontWeight: FontWeight.w400)),
const SizedBox(height: 20.0),

height: 180.0,

return Row(
crossAxisAlignment: CrossAxisAlignment.start,

This was happened because you use expanded in row inside horizontal listview, you have two option :
One: remove the expanded widget inside Row inside itemBuilder.
Two: set width for item inside itemBuilder:
itemBuilder: (context, index){
return SizedBox(
width: 400.0, // <--- add this
child: return Row(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Container(
height: 150.0,
...
);
}

How to fix Bottom Overflowed by 10 Pixels?

As you can see in the these two photos below, this problem happened only when the address contains many words, if the address contains fewer words I don't see any issues, I got stuck here and can't think anymore :)
what shall I do in this case, please?

Try to wrap your Text() widget with a Flexible(). This should size your widget to make the Text fit.
More here
So i fixed it by adding maxLines and added softWrap and set it to true, (thanks to #Marcel Dz) for his suggestion, but it doesn't work with only Wrap the text with Flexible.
The problem is that the address is changeable, every address has a different number of words, when the address is long it's mean more words and these words are pushing the Button to the bottom because there's no more free space to show the full words of address.
here is the piece of code that i modified:
Expanded(
child: Text(e,
overflow: TextOverflow.visible,
maxLines: 3,
softWrap: true,
style: Theme.of(context).textTheme.bodySmall),
),
Another solution with Flexible:
Flexible(
child: Text(e,
overflow: TextOverflow.visible,
maxLines: 3,
softWrap: true,
style: Theme.of(context).textTheme.bodySmall),
),
Result:
Now it's working perfectly, and i can have as many words as i need, both Expended and Flexible can be used.

Text Overflowing in a Row, Flutter

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,
),
);

overflowing flutter columns and rows

I have this list view in flutter which I am trying to make into a chat list. Similar to what you see in WhatsApp and telegram. However I am struggling to get the idea of how rows and columns work because I keep getting overflows.
Here is the code:
ListView(
physics: BouncingScrollPhysics(),
children: [
Dismissible(
key: Key(""),
background: Container(color: Colors.grey[200]),
direction: DismissDirection.endToStart,
child: InkWell(
onTap: () {},
child: Column(
mainAxisSize: MainAxisSize.max,
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Flex(
direction: Axis.vertical,
children: [
Text("Hello"),
],
),
Flex(
direction: Axis.vertical,
children: [
Text(
"al;skdl;aksd a;skd ;aks;dk a;skd ;laks;d a;lsk d;lkas; dka;lsk d;laks; ldka;slk d;a",
overflow: TextOverflow.ellipsis,
maxLines: 2,
),
],
),
],
),
),
),
],
Now we often experience the text overflow problem so if we think it that we we have provided column a particular width and restricted it but if we wrap the things up with flexible widget it now tells column/Row that you can change your size and be flexible
order would be
flexible > Container > Column/Row
The reason we are applying this to container is Column/Row will ask immediate parent for width and height
now this problem can also be solved by text overflow property that is we can clip text but what if we dont want too
So all you have to do is Wrap the column/Row in Container and then into Flexible as now it will tell container that yes you can adjust your height
Your concept can be cleared by how actually widgets parent child relationship works i.e in brief
basically If am a child I will ask my parent okay what is my size so since my parent if it has a size it will bound me but if it doesnt has a size it will ask its parent okay tell me what space should I take and it goes on. Expanded and Flexible says that okay you can adjust yourself instead of being Fixed.
Flexible(
child: Container(
margin: EdgeInsets.only(left: 10.0,right: 10.0),
child: Column(
mainAxisAlignment: MainAxisAlignment.start,
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Text('${dataBookTitleSearch1[index]} ', style: kGoodSearchResultTextStyle, textAlign: TextAlign.left,),
SizedBox(
height: 10.0,
),
Text('${dataBookAuthorSearch1[index]}', style: kGoodSearchResultTextStyle,textAlign: TextAlign.left),
SizedBox(
height: 10.0,
),
Text('${dataBookExtensionSearch1[index]} ', style: kGoodSearchResultTextStyle,textAlign: TextAlign.left),
SizedBox(
height: 20.0,
),
Container(
width: 80.0,
height: 40.0,
decoration: BoxDecoration(
borderRadius: BorderRadius.all(Radius.circular(20.0)),
color: Colors.white
),
child: Padding(
padding: const EdgeInsets.only(left:20.0,top: 12.0),
child: Text('Read'),
),
),
],
),
),
)

Dynamic height of listview builder item

I am unable to set the dynamic size to my list item of list view builder, every time it shows blank screen and when I specify a constant size it works.
I tried by using column by setting mainAxisSize=minimum and by using container as we know container wraps the child height but nothing works
listItem (GuideLines news) =>Column(
mainAxisAlignment: MainAxisAlignment.start,
mainAxisSize: MainAxisSize.min,
children: <Widget>[Container(
decoration: BoxDecoration(image: new DecorationImage(image: AdvancedNetworkImage(
"${news.featured_image}",
useDiskCache: true,
cacheRule: CacheRule(maxAge: const Duration(days: 7)),
),fit: BoxFit.cover)),
margin: EdgeInsets.only(bottom: 10.0),
child: ListTile(
onTap: (){
print(news.web_link);
Navigator.push(context, MaterialPageRoute(builder: (context) => NewsDetailsPage(news)));
},
title: new Container(
margin: EdgeInsets.only(left: 30.0),
child: Column(
mainAxisAlignment: MainAxisAlignment.start,
crossAxisAlignment: CrossAxisAlignment.start,
mainAxisSize: MainAxisSize.max,
children: <Widget>[
Padding(
padding: const EdgeInsets.only(top: 20.0),
child: new Text("${DateFormat("E, d MMM y").format(CommonService.dateFormat(news.publish_date.toString()))}", style: TextStyle(fontFamily: 'SF-Display-Regular' ,fontSize: 13.0 ,color: Colors.white),),
),
SizedBox(height: 13.0),
new Flexible(
child: new Container( width: MediaQuery.of(context).size.width *0.45,
child: Padding(
padding: const EdgeInsets.only(bottom: 20.0),
child: new Text("${news.title}" ,maxLines: 3, overflow: TextOverflow.ellipsis, style: TextStyle(fontFamily: 'SF-Display-Semibold' ,fontSize: 22.0 ,color: Colors.white),),
)
),
)
],
)),
trailing: Padding(
padding: const EdgeInsets.only(right: 20),
child: Row(
mainAxisSize: MainAxisSize.min,
children: <Widget>[Icon(Icons.arrow_forward_ios, color: Colors.white),SizedBox(width: 8,)],
),
),
),
)],
);
Just add these two properties of shrinkWrap and physics to make the height of list dynamic
ListView.builder(
shrinkWrap: true,
physics: NeverScrollableScrollPhysics(), //Optional
itemCount: size,
itemBuilder: (context, position) {}
),
The problem with your code is, that you used a Flexible widget in a Column. A Flexible widget expands to the remaining space of the Column or Row. However, this only works if you have restricted the size of the Column or Row widget. Because otherwise, the size of the element in the Column would expand to infinity as the remaining space is not restricted and therefore also infinity.
When using Flexible or Expanded widgets you always need to restrict their parent size, else you get this error:
RenderFlex children have non-zero flex but incoming height constraints
are unbounded. When a column is in a parent that does not provide a
finite height constraint, for example if it is in a vertical
scrollable, it will try to shrink-wrap its children along the vertical
axis. Setting a flex on a child (e.g. using Expanded) indicates that
the child is to expand to fill the remaining space in the vertical
direction.
The solution and some cleanup of your code:
Widget listItem(GuideLines news) {
return Container(
decoration: BoxDecoration(
image: DecorationImage(
image: AdvancedNetworkImage(
"${news.featured_image}",
useDiskCache: true,
cacheRule: CacheRule(maxAge: const Duration(days: 7)),
),
fit: BoxFit.cover),
),
margin: EdgeInsets.only(bottom: 10.0),
child: ListTile(
onTap: () {
print(news.web_link);
Navigator.push(context, MaterialPageRoute(builder: (context) => NewsDetailsPage(news)));
},
title: Container(
margin: EdgeInsets.only(left: 30.0),
child: Column(
mainAxisAlignment: MainAxisAlignment.start,
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Padding(
padding: const EdgeInsets.only(top: 20.0, bottom: 13.0),
child: Text(
"${DateFormat("E, d MMM y").format(CommonService.dateFormat(news.publish_date.toString()))}",
style: TextStyle(fontFamily: 'SF-Display-Regular', fontSize: 13.0, color: Colors.white),
),
),
Container(
width: MediaQuery.of(context).size.width * 0.45,
padding: const EdgeInsets.only(bottom: 20.0),
child: new Text(
"${news.title}",
maxLines: 3,
overflow: TextOverflow.ellipsis,
style: TextStyle(fontFamily: 'SF-Display-Semibold', fontSize: 22.0, color: Colors.white),
),
)
],
),
),
trailing: Padding(
padding: const EdgeInsets.only(right: 28),
child: Icon(Icons.arrow_forward_ios, color: Colors.white),
),
),
);
}
In your specific case, this Flexible widget was redundant anyway.
