I'm trying to create a vertical text using the RotatedBox. The widget works well and the text is rotated accordingly, but when the text is too long it is automatically expanded to the right which is not the behavior I wanted.
RotatedBox(
quarterTurns: -1,
child: Tooltip(
message: "the long text message when user wants to see it",
child: Container(
width: 50,
child: Text("some long text that is too long to fit",
overflow: TextOverflow.fade,
),
)),
),
As shown on the image above, the text isn't clipped using overflow instead it just expands to the right creating that awkward gap.
I've tried adding more containers to the RotatedBox, unfortunately it doesn't limit it's size at all.
I fixed this by adding height and width on the container outside the RotatedBox
Container(
height: 50,
width: 20,
child: RotatedBox(
quarterTurns: -1,
child: Tooltip(
message: "the long text message when user wants to see it",
child: Text("some long text that is too long to fit",
overflow: TextOverflow.fade,
)),
),
),

I want to make an image preview gallery like this. The height for the image is fixed to 150px using SizedBox. So I do not know the actual width of the image, depends on its aspect ratio.
Now, I want to have a description text, which I add as a column:
child: Column(
mainAxisSize: MainAxisSize.min,
children: [
SizedBox(
height: 150,
child: Image.file(
File(artifacts[index].localartifactPath!),
fit: BoxFit.contain,
),
),
Text("Hello everyone this is my text",
maxLines: 2,
softWrap: true,
overflow: TextOverflow.ellipsis,
style: Theme.of(context).textTheme.bodySmall)
]),
But I do not want that the text is longer in width than the image, if the text is too long, it shall break into a second line and if still to long, it should use the ellipsis....
Is there any way to tell the Text widget not be longer (set constraints) in width than the Image widget?
Thanks!
I want to add a tapable icon right after a long text. I need to use Text widget since I'm using textDirection and maxLines params.
Any ideas?
The problem:
What I need to get:
as Karen said it we need to use RichText.
Text.rich(
TextSpan(
text:
"I want to add a tapable icon right after a long text. I need to use Text widget since I'm using textDirection and maxLines params.",
children: [
WidgetSpan(
child: Icon(
Icons.error_outline,
color: Colors.red,
),
),
]),
),
the one way is to get char code of an icon, take a look at this answer for more details.

Use a stack, let me show you...
Container(//Stack Widget needs space to work so be sure to add a container that gives it
width: double.infinity, //this makes the container match with the screen width
height: 200,
color: Colors.red,
child: Stack(
children: [
Positioned(//This widget gives position to your button
top: 100,//This will create a space on top
left: 0,//This will create a space on left
child: Container(//Your Container and text widget here
margin: EdgeInsets.only(left: 100),
height: 100,
width: 200,
color: Colors.blue,
child: Text(
"This is my text, my text takes more than one line, I want to present my Icon at the end of this text"
),
)
),
Positioned(
top: 140,
left: 150,
child: IconButton(//Put here your icon widget
iconSize: 30,
icon: Icon(CupertinoIcons.arrow_left_circle_fill),
color: Colors.blue,
)
),
],
),
)
I am using SfRadialGauge plugin its working fine but there I am facing 2 issues.
Its showing lot of space on top, if I give height to container the sizes of SfRadialGauge is reducing also the top space I don't want to reduce size I just want to remove the space
Same space in GaugeAnnotation. I have column inside GaugeAnnotation and need to show little on top.
My code
Widget getSemiCircleProgressStyle() {
return Padding(
padding: const EdgeInsets.all(0.0),
child: Container(
child: SfRadialGauge(axes: <RadialAxis>[
RadialAxis(
showLabels: false,
showTicks: false,
startAngle: 180,
canScaleToFit: true,
endAngle: 0,
radiusFactor: 0.8,
axisLineStyle: AxisLineStyle(
thickness: 0.1,
color: const Color.fromARGB(30, 0, 169, 181),
thicknessUnit: GaugeSizeUnit.factor,
cornerStyle: CornerStyle.startCurve,
),
pointers: <GaugePointer>[
RangePointer(
value: 100,
width: 0.1,
sizeUnit: GaugeSizeUnit.factor,
enableAnimation: true,
animationDuration: 100,
animationType: AnimationType.linear,
cornerStyle: CornerStyle.bothCurve)
],
annotations: <GaugeAnnotation>[
GaugeAnnotation(
positionFactor: 0,
widget: Container(
child: Stack(
alignment: Alignment.center,
children: [
Column(
crossAxisAlignment: CrossAxisAlignment.center,
mainAxisAlignment: MainAxisAlignment.center,
children: [
Padding(
padding: const EdgeInsets.all(0.0),
child: RatingBarIndicator(
rating: 0.2,
itemBuilder: (context, index) => Icon(
Icons.star,
color: Color(0xffF4D03F),
),
itemCount: 1,
itemSize: 45.0,
direction: Axis.vertical,
),
),
RichText(
text: new TextSpan(
// Note: Styles for TextSpans must be explicitly defined.
// Child text spans will inherit styles from parent
style: new TextStyle(
fontSize: 14.0,
color: Colors.black,
),
children: <TextSpan>[
new TextSpan(
text: '2',
style: new TextStyle(
fontSize: 40, fontFamily: 'UbuntuRegular')),
new TextSpan(
text: ' /5',
style: TextStyle(
fontSize: 25,
color: Colors.grey[400],
fontFamily: 'UbuntuRegular')),
],
),
),
Text(
'FIFTEEN DAYS SCORE',
style: TextStyle(
color: Colors.grey[400], fontFamily: 'UbuntuMedium'),
)
],
)
],
),
))
]),
])),
);
}
This is how its look like
I have marked the space with red pen. IF any one can help to reduce these spacing I am stuck on this from a day :(
Been having the same problem too.
I found that the solution is to set :
canScaleToFit: false
But, this only works if you use the default circular gauge. For the semi-circular gauge, it will still left some blank spaces at the bottom.
I had the same problem, I guess I'm late but hopefully this can be useful to others.
Premises
Note. At the moment I can't find a way to have FULL control of this widget's white space. I only have found the following workaround to get rid of the white space above and under the gauge.
The library's devs mentioned two things:
"... For better understanding, say if the container has different width and height (say 300x800), we will always take the lowest dimension (here it is the width) to render the radial gauge ..."
"... We are sorry that we cannot provide any workaround to trim ..."
"... as this is the default rendering behaviour of the Radial gauge, we cannot consider your suggestion as a feature request."
The first statement is really useful, as it enables a workaround (see below).
The second statement.. I disagree, that's not something "impossible" to work around with.
The third statement... well that's just depressing.
Workaround
Thanks to the Flutter DevTools, I noted that the Gauge renders a NeedlePointer Widget, which is the one rendering the cursed white space. As the devs mentioned, the gauge takes as much space as it can in the smallest direction.
This means that as long as you restrict height and width, you should be fine. I don't know in which context your Gauge is, but in mine the following code works great.
return LayoutBuilder(
(context, constraints) => Container(
padding: const EdgeInsets.all(0),
height: constraints.maxWidth / 1.5, // WORKAROUND
child: Column(
children: [
Flexible(
child: SfRadialGauge(...),
),
MaybeSomeLabelsWidgets(),
SomeOtherWidgets(),
],
),
),
);
So, the fundamental part here is the fact that height is restricted and that there's a Flexible Widget that lets the Gauge take minimum space. LayoutBuilder in my case/context is useful just because I wanted to render the plot with a "3x2" feeling.
As a last note, keep the canScaleToFit=true, so that your plot is centered (why is it called canScaleToFit? That's another mistery I guess...).
Let me know if this helps.
A simple workaround is to use the ClipRect widget. The following will discard the top 20% of the SfRadialGuage.
ClipRect(
child: Align(
alignment: Alignment.bottomCenter,
heightFactor: 0.8,
child: SfRadialGauge(...)
)
)
I broke my brain trying to find a solution. I have a row constrained by screen width and unconstrained by height. Here is an example, constrained by Container for simplicity:
Container(
color: Colors.blue[100],
width: 300,
child: Row(
mainAxisSize: MainAxisSize.max,
children: [
Container(width: 24, height: 24, color: Colors.red),
Flexible(
fit: FlexFit.tight,
child: Text('$name', overflow: TextOverflow.ellipsis)
),
Flexible(
fit: FlexFit.tight,
child: Text('$value', overflow: TextOverflow.ellipsis, maxLines: 10, softWrap: true, textAlign: TextAlign.right)
)
]
)
)
I need to size name and value according to this requirements:
Consider red square as icon with constant size
name is always 1 line with ellipsis if overflowed
value can be up to 10 lines with ellipsis if overflowed
In most cases value is pretty short, so name should take all available space
When value is long, it should take up to 10 lines in height and all available space in width leaving only 50 pixels for name. And 24 for icon of course. So name should have min width of 50px.
I have no idea how to achieve this. Please help.
P.S. I wrote a big Flutter project, solved huge amount of tricky tasks and Widget puzzles but this thing is something unbelievable.
I've got a Column indide a Scaffold, and one of the Column's children is a TextField. I'd like the Textfield to expand and take all the available space, but if there is not enough space (basically when the keyboard shows up), I want the Textfield to be 3 lines height min and the Column to be scrollable so the focus on the Textfield works as intended.
I've tried a lot of different widgets, like Expand, IntrinsicHeight, LayoutBuilder, ConstrainedBox, SingleChildScrollView...
But none of the tested combination did work as expected...
The SingleChildScrollView page did help me a lot but none of the example match my situation :
https://docs.flutter.io/flutter/widgets/SingleChildScrollView-class.html
Scaffold(
body: Column(
children: <Widget>[
Text("Some\nvery\nvery\nvery\nvery\nvery\nvery\nvery\nvery\nvery\nvery\nvery\nlong\ntext"),
RaisedButton(child: Text("Some button")),
Text("Second line"),
Expanded(
child: Padding(
//Use the expand parameter instead of padding + maxLines, once released : https://github.com/flutter/flutter/pull/27205
padding: const EdgeInsets.only(top: 10, bottom: 30),
child: TextField(
decoration: InputDecoration(
hintText: "Message...",
),
maxLength: 500,
maxLengthEnforced: true,
maxLines: 50,
),
),
),
Center(
child: RaisedButton(
child: Text('OK'),
onPressed: _send,
),
)
],
),
)
With that code the first part works fine : when not keyboard is shown, the Textfield is expanded as expected.
But when the keyboard shows up, the layout overflow (because there is no SingleChildScrollView).
EDIT : the new TextField.extends property helped a bit but didn't solved my issue...
