i have a simple code
RaisedButton(
onPressed: () {
model.resetmodem();
},
child: Text(
'Size (also 24 pixels, not coincidentally, since both FlutterLogo and Icon honor the ambient IconTheme). This leaves some room left over, and now the row tells the text exactly how wide to be: the exact width of the remaining space. The text, now happy to comply to a reasonable request, wraps the text ',
maxLines: 2,
overflow: TextOverflow.ellipsis,
),
color: Colors.blue,
textColor: Colors.white,
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(25)),
),
I want to add an icon in front of the text but I don't want to overflow the text
Use Row and put this text and icon inside it if it overflows you got to lower font sized or icon size or make your button bigger
You could you RichText along with InkWell like:
InkWell(
onTap: () {
//Your code here
},
child: RichText(
text: TextSpan(
text: 'Size (also 24 pixels, not coincidentally, since both FlutterLogo and Icon honor the ambient IconTheme). This leaves some room left over, and now the row tells the text exactly how wide to be: the exact width of the remaining space. The text, now happy to comply to a reasonable request, wraps the text ',
children: [
WidgetSpan(child: Icon(Icons.done)),
]),
),
)

So I have two SwitchListTiles on my modal Page, and the problem is that the text doesn't fit into it. (it takes 3 lines, but should 1)
How can I make it to be in one single line, without decreasing it's font size
child: SwitchListTile(
value: state.filter.flagId == null ? false : true,
onChanged: (newValue) =>
context.read<FilterBloc>().add(HotPressed(newValue)),
title: Text(
AppLocalizations.of(context)!.hotAdds.capitalize(),
style: FlutterFlowTheme.dark50016.copyWith(),
),
tileColor: FlutterFlowTheme.white,
activeColor: FlutterFlowTheme.primaryColor,
dense: true,
controlAffinity: ListTileControlAffinity.trailing,
),
I was thinking that the possible answer could be to decrease the distance between tile, but don't know how to do it
Just add "maxLines: 1" to Text widget
title: Text(
AppLocalizations.of(context)!.hotAdds.capitalize(),
style: FlutterFlowTheme.dark50016.copyWith(),
maxLines: 1,
),
There is default padding on the outer edges and also between the text and the switch. From what I can see the outer padding (the padding to the right of the switch and to the left of the text) defaults to 16. You can change this by adding contentPadding as an input to SwitchListTile and set the value to something smaller than 16:
contentPadding: EdgeInsets.symmetric(horizontal: 5),
But I'm not sure if you can change the padding between the text and the switch.
wrap your text widget to Flexible and trim() your text to avoid enter(\n) as string. maxLines =1.
title: Flexible(
child: Text(
AppLocalizations.of(context)!.hotAdds.capitalize().trim(),
style: FlutterFlowTheme.dark50016.copyWith(),
maxLines: 1,
),
),
I'm trying to set a layout inside MaterialBanner. I need to set the red-colored widget in the bottom to the left. However, I cannot figure it out how and the square widgets are always right-aligned.
Here is my sample code.
If you know how to implement it, I would like to know the tip. Thank you.
MaterialBanner(
forceActionsBelow: true,
actions: <Widget>[
RaisedButton( // Tried Row, Expanded Widget but neither works
child: Text('Red'),
color: Color(0xff49A9EF),
),
RaisedButton(
child: Text('Blue 1'),
color: Color(0xff49A9EF),
),
RaisedButton(
child: Text('Blue 2'),
color: Color(0xff49A9EF),
),
],
content: Text(
'text text text text text text text text text text text text text text text text text text ',
overflow: TextOverflow.ellipsis,
maxLines: 2,
),
...
)
I've tried this and I can answer why the Red Box doesn't move to the left.
The actions list of Widgets is always set to AlignmentDirectional.centerEnd so there is no way you can place a Widget in the actions list and expect it to be elsewhere.
What if the red box was passed to the leading property of the MaterialBanner Widget. Then we see that the box aligns on the top left with the provided content. Even when the padding is stripped off completely from the leading Widget it sticks to the top left.
Any reason why you wouldn't write a custom Widget to accomplish this ?
Did you ever experience this? Does it make sense to register this as a bug and how would I do this?
For one of my screens I have now this situation for the 2nd time: I insert a CupertinoButton with Text as a child, however, the text does not show up. In the 1st occurrence, 2 pixels of text appeared to be rendered (I saw 2 dots). I have also copied a CupertinoButton from another line and left it unchanged. No change, text does not appear. If I then only change the widget name from CupertinoButton to FlatButton (leaving everything else untouched), the text appears.
Since CupertinoButtons are typically working for me, I guess I would have to submit the whole project for a bug report, since isolating the issue does not to be appear like a straight forward job.
Please consider adding padding like this:
CupertinoButton(
padding: EdgeInsets.symmetric(vertical: 0, horizontal: 5),
color: Colors.blue,
borderRadius: BorderRadius.all(Radius.circular(12)),
child: Text(
'Login',
style: TextStyle(
fontSize: 16,
fontWeight: FontWeight.bold,
color: Colors.white),
),
onPressed: () => {},
),
I am using Flutter programming. I need to display a title and a button next to the title. If the text length is less button also should display next to the text. If text length is more i want to fix the text length as maximum 200px and need to show the button next to the title.
I am using the below code. And working fine with the less text length.
Problem is: If text length is more, then my button is moving out of screen. You can see the behaviour in the below attached image.
Row(
children: <Widget>[
Container(
child: RichText(
overflow: TextOverflow.ellipsis,
strutStyle: StrutStyle(fontSize: 12.0),
text: TextSpan(
style: TextStyle(color: Colors.white), text: model.title),
),
),
Text("My Button"),
],
)
You can put maximum characters
text.substring(0,150)
I think there's no maxLength property for RichText and Text widget. If you are using RichText class, you'll have maxLines property that can be used. I tried to recreated your case and wrapped RichText widget with Flexible widget that lets the child widget to use only the minimum available space. But I wasn't able to replicate the error you mentioned. The long text I used gets ellipsis and the button doesn't go out of the screen. Note that I also used maxLines property which if you set to 2, will wrap the long text in new line without moving away the button and the long text will be shown as ellipsis. Sample working code below:
body: Center(
child: Row(
children: <Widget>[
Container(
child: Flexible(
child: RichText(
maxLines: 2,
overflow: TextOverflow.ellipsis,
strutStyle: StrutStyle(fontSize: 12.0),
text: TextSpan(
style: TextStyle(color: Colors.white), text: 'I am using Flutter programming. I need to display a title and a button next to the title. If the text length is less button also should display next to the text. If text length is more i want to fix the text length as maximum 200px and need to show the button next to the title.'),
),
)
),
Text("My Button"),
],
)
)
If you set maxLines to 1, the long text will wrap in ellipsis.
Hope this helps.
String addressText = userAddress.address.toString();
if(addressText.length > 22)
addressText = addressText.substring(0,22);
You can check length and split string if exceeds max length.
you can use Expanded or give fixed width to container of rich text, like this with Expanded widget:-
Row(
children: <Widget>[
Expanded(
child: RichText(
overflow: TextOverflow.ellipsis,
strutStyle: StrutStyle(fontSize: 12.0),
text: TextSpan(
style: TextStyle(color: Colors.white), text: model.title),
),
),
Text("My Button"),
],
)
I have a Text widget and not sure why it seems to just have padding at the top and bottom even though I didn't set any in the code. This is from the default Flutter app, I just modified the font size.
body: Center(
child: Column(
children: <Widget>[
Text(
'0:00.00',
style: TextStyle(fontSize: 76),
),
],
),
),
This is a screenshot of the highlighted Text widget in Android Studio. There's really nothing else adding any padding so I don't know why it's there.
Sometimes you get this in CSS where there is padding even though none was set but you can remove it simply with padding: 0 but I don't see how to do it here since I can't find a padding option for the Text widget.
EDIT: The amount of padding changes with the size of the font. It seems to always contain a certain amount of padding, like a html H1 tag.
The proper way you can get rid of the unwanted padding is by setting the height property in the TextStyle. With this you set the height for each line.
Text(
"Let's make\nsome pancakes",
style: TextStyle(
height: 1.2, //SETTING THIS CAN SOLVE YOUR PROBLEM
color: Colors.white,
fontSize: 20,
fontWeight: FontWeight.w300,
),
textAlign: TextAlign.center,
),
In fact, we can confirm from the docs that:
For most fonts, setting height to 1.0 is not the same as omitting or setting height to null because the fontSize sets the height of the EM-square, which is different than the font provided metrics for line height.
For more info: https://api.flutter.dev/flutter/painting/TextStyle/height.html
So give it a try. It worked for me.
There are reasons why the Text widget has this "padding". Take in consideration the next example:
Text(
'123 gyÓ',
style: TextStyle(
fontSize: 40.0,
),
),
As we can see, using another characters like the letters g and y and an uppercase O with an accent marker, shows us that there's no padding on the Text widget really.
Fonts have ascenders and descenders on some characters, and there's also en ascent line for special characters like the accent marker. That's why numbers are centered in the middle. That's not padding on Flutter side, but typography design(?). Maybe you could find a way to sort your issue, by looking for a font without ascenders and descenders.
More info about fonts on Wikipedia
Conclusion: if you want to select the Text widget with the Flutter inspector, and see no space around some characters, that is not possible.
I think I found a good solution/workaround for removing both top and bottom padding.
The trick is to put your Text in a Container and then change the height of your TextStyle inside the Text, as well as the height of your Container. It's a bit of going back and forth for the perfect measurements but it's worth it imo.
Here's an example from my own code.
Container(
height: 24,
child: Text(
'Auto',
style: TextStyle(
height: 0.77,
fontSize: 32,
fontWeight: FontWeight.bold,
color: Colors.white,
),
textAlign: TextAlign.center,
),
There are 2 potential reasons:
The fontFamily - try commenting it out and see if you still have the same problem. If this is the reason and you absolutely must/want to use this specific font, I'm not sure what the fix is, apart from some horrible logic to stack widgets accordingly so that it looks like there's no padding.
Layout constraints from the parent Widgets - you only included the code of the Text widget, but if for example it's wrapped in an Expanded widget within a Column, that would also explain the extra height (possibly wrong assumption here because the text wouldn't center itself vertically by default anyway, but then there might be a DefaultTextStyle widget up in the hierarchy somewhere so still possible....)
Edit: It seems like there is some default padding around the text.
I found that you can reduce the top padding by setting a TextStyle with a height lower than 1. The value required seems to depend on the font size and the text itself, as different characters have different heights.
You can also reduce the bottom padding by clipping the Text using a fixed size Container. This will also vary based on the font size and the text itself. Below is an example of using both of these to reduce the top and bottom padding to 0 for the text '0:00.00' of font size 72:
ClipRect(
child: Container(
height: 55,
child: Text("0:00.00",
style: TextStyle(
fontSize: 72,
height: 0.80,
),
),
),
),
I know this is a very poor solution, but I don't know of any better one. I tried using a custom StrutStyle on the Text widget, but that didn't help either.
Try playing with line height of the text by setting height in style property. Height of the text is determined based on font size. It will multiply the font size and give you the space that will look like it has some padding. The line height of the text is also linked to the font itself, since every font has it own line height.
child: Text(
'Some text goes here',
style: TextStyle(
fontSize: 25.0,
height: 1,
),
)
I found the solution myself in the end. It can be positioned using Stack and Row widgets. I found Row works better than using Positioned as the text can be centred using the Row widgets.
body: Stack(
children: <Widget>[
Row(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Text(
'0:00.00',
style: TextStyle(fontSize: 76),
),
],
),
Padding(
padding: EdgeInsets.only(top: 56.0),
child: Row(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Text(
'Coke',
style: TextStyle(fontSize: 76),
),
],
),
),
],
)
It kind of works like the negative padding in CSS but actually it's the padding that moves the bottom text down rather than up since otherwise they occupy the same space.
After googling a while, I've written this.
What does it do? It's shifting down the position of the text
(not shrinking)
import 'package:vector_math/vector_math_64.dart';
import 'package:flutter/material.dart';
class BaselineText extends StatefulWidget {
final Widget child;
BaselineText({this.child});
#override
_BaselineTextState createState() => _BaselineTextState();
}
class _BaselineTextState extends State<BaselineText> {
GlobalKey _key = GlobalKey();
void initState() {
super.initState();
WidgetsBinding.instance.addPostFrameCallback((_) => setState(() {}));
}
#override
Widget build(BuildContext context) {
final RenderBox renderBox = _key.currentContext?.findRenderObject();
final height = renderBox?.size?.height ?? 0;
return Baseline(
baseline: 0,
baselineType: TextBaseline.ideographic,
key: _key,
child: Transform(
transform: Matrix4.translation(
Vector3(0, height, 0),
),
child: widget.child,
),
);
}
}
How to use:
BaselineText(
child: Text("something"),
)
DONE!!!
