I want to show an icon in text widget. How do I do this ?
The following code only shows the IconData
Text("Click ${Icons.add} to add");
Flutter has WidgetSpan() to add a widget inside the RichText().
Example use:
RichText(
text: TextSpan(
children: [
TextSpan(
text: "Click ",
),
WidgetSpan(
child: Icon(Icons.add, size: 14),
),
TextSpan(
text: " to add",
),
],
),
)
Above code will produce:
You can treat the child of WidgetSpan like the usual widget.
Screenshot:
Using Wrap:
Wrap(
crossAxisAlignment: WrapCrossAlignment.center,
children: [
Text('Click'),
Icon(Icons.add),
Text('to add'),
],
)
Using Row:
Row(
mainAxisSize: MainAxisSize.min,
children: [
Text('Click'),
Icon(Icons.add),
Text('to add'),
],
)
Using Text.rich:
Text.rich(
TextSpan(
children: [
TextSpan(text: 'Click'),
WidgetSpan(child: Icon(Icons.add)),
TextSpan(text: 'to add'),
],
),
)
An alternative might be to use emoji.
In Dart, strings supports escape sequences for special characters. For unicode emoji, you can use \u and curly braces with emoji hex code inside. Like this:
Text('Click \u{2795} to add')
The result is:
You can find a complete unicode emoji list here: http://unicode.org/Public/emoji/1.0/emoji-data.txt
Row Widget can be one solution for this issue, but you have to use different widgets to make it happen.
Follow below example.
Row(
children: <Widget>[
Text("Hi"),
Icon(Icons.add),
Text("Hello")
]
)
Another option is String.fromCharCode(int charCode)
This is icons.dart created by flutter team and charCodes are can found here.
RichText(
text: TextSpan(
style: TextStyle(
color: Colors.black,
fontSize: 24.0,
),
text: 'This is alarm icon : ',
children: <TextSpan>[
TextSpan(
text: String.fromCharCode(0xe190), //<-- charCode
style: TextStyle(
fontFamily: 'MaterialIcons', //<-- fontFamily
fontSize: 24.0,
color: Colors.red,
),
)
],
),
)
And result :
I think it's better to use the Row widget. here is an example
Row(
children: [
Icon(Icons.download_rounded),
Text(" Download")
],
)
You can use WidgetSpan() on Text.rich().
Here's a link for InlineSpan-class.
You can use this Package to achieve this.
I am not able to find the pub of this package.
Here is the Implementation.
RealRichText(
[
TextSpan(
text: "A Text Link",
style: TextStyle(color: Colors.red, fontSize: 14),
recognizer: TapGestureRecognizer()
..onTap = () {
debugPrint("Link Clicked.");
},
),
ImageSpan(
AssetImage("packages/real_rich_text/images/emoji_9.png"),
imageWidth: 24,
imageHeight: 24,
),
ImageSpan(AssetImage("packages/real_rich_text/images/emoji_10.png"),
imageWidth: 24,
imageHeight: 24,
margin: EdgeInsets.symmetric(horizontal: 10)),
TextSpan(
text: "哈哈哈",
style: TextStyle(color: Colors.yellow, fontSize: 14),
),
TextSpan(
text: "#Somebody",
style: TextStyle(
color: Colors.black, fontSize: 14, fontWeight: FontWeight.bold),
recognizer: TapGestureRecognizer()
..onTap = () {
debugPrint("Link Clicked");
},
),
TextSpan(
text: " #RealRichText# ",
style: TextStyle(color: Colors.blue, fontSize: 14),
recognizer: TapGestureRecognizer()
..onTap = () {
debugPrint("Link Clicked");
},
),
TextSpan(
text: "showing a bigger image",
style: TextStyle(color: Colors.black, fontSize: 14),
),
ImageSpan(AssetImage("packages/real_rich_text/images/emoji_10.png"),
imageWidth: 24,
imageHeight: 24,
margin: EdgeInsets.symmetric(horizontal: 5)),
TextSpan(
text: "and seems working perfect……",
style: TextStyle(color: Colors.black, fontSize: 14),
),
],
);

For simple icons, You can use a Unicode character as regular text, just copy and paste.
You can search and copy Unicodes from this site
Text("Enjoy! 🔎❌💖🔥✅💜😍")
This method will work with any Text widget and package.
You can use this function:
Widget _spanIcon(String text, IconData icon, TextStyle st) {
return Row(
children: [
Text(text,style: st,),
Text(
String.fromCharCode(icon.codePoint), //<-- charCode from icon data
style: TextStyle(
fontFamily: icon.fontFamily, //<-- fontFamily from icon data
fontSize: st.fontSize! + 4.0,//you can increase font size for icon here
color: st.color,
),)
],
);}
and then use it :
_spanIcon('11',Icons.access_alarm, TextStyle(fontSize: 14.0, color: Color.fromARGB(113, 0, 0, 0))),

I am using get's obx() like below code.
But I want the title to be centered.
But I can't even use "align", so I'm curious how to align it.
title:
Obx(
() => Text.rich(
TextSpan(
text:
"${_questionController.questionNumber.value}. ",
style: TextStyle(fontSize: 15, color: Colors.blue),
children: [
TextSpan(
text: '${Questiontitle[widget.index]}',
style: TextStyle(fontSize: 15, color: Colors.blue),
),
],
),
),
),
Wrap title with Center or with Align and set alignment to Alignment.center.
How can I add the iconbutton at the end of the text like this ?

I use Row widget but the iconbutton is not in the right place, it is not at the end of the text
Pic
This is my code:
Row(
children: [
Expanded(
child: Text(
'All about marketing, lead generation, content marketing and growth hacks',
style: const TextStyle(
fontSize: 12.0, fontWeight: FontWeight.w500),
),
),
IconButton(
icon: Icon(Icons.info),
iconSize: 12.0,
color: Palette.appbar,
onPressed: () {},
),
],
),
Use RichText with TextSpan and WidgetSpan.
WidgetSpan allow to add your own widget as a part of text.
like this :
RichText(
text: TextSpan(
children: <TextSpan>[
TextSpan(text: _text, style: _style),
WidgetSpan(
child: _child
)
],
),
I am trying to create the picture below in Flutter. As you can see, I need a link and an image icon. However, I am getting the "range" error in the console.
Here a snippet of my code
Widget build(BuildContext context) {
return Row(
mainAxisAlignment: MainAxisAlignment.start,
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Image.asset(
"assets/images/checkbox-check.png",
),
Expanded(
child: Container(
child: Wrap(
children: [
RichText(
text: new TextSpan(
children: [
TextSpan(
text: 'Email opportunities. ',
style: TextStyle(
color: Palette.DARK_BLUE, fontSize: 16.0),
),
TextSpan(
text: 'privacy policy',
style: TextStyle(
color: Palette.DARK_BLUE,
decoration: TextDecoration.underline),
recognizer: TapGestureRecognizer()
..onTap = () {
launch();
},
),
TextSpan(
text: ' and ',
),
TextSpan(
text: 'terms of use',
style: TextStyle(
decoration: TextDecoration.underline),
recognizer: TapGestureRecognizer()
..onTap = () {
launch();
},
),
WidgetSpan(
child: Icon(
Icons.info_outline,
color: Colors.red,
),
)
],
),
),
],
),
),
)
],
);
}
}
Is there another method to create my UI? I don't get an error screen but I see the error in the console. I have a wrap in the widget tree but don't think I need it. but never the less, same issue if I remove it.
This is a Flutter issue when you use TextSpan with recognizer together with WidgetSpan: https://github.com/flutter/flutter/issues/51936
A workaround is to wrap RichText in ExcludeSemantics:
ExcludeSemantics(
excluding: true,
child: RichText( ... ),
),
I'm trying to make privacy policy and terms of service link.
Widget privacyPolicyLinkAndTermsOfService() {
return Container(
child: Center(
child: Text(
'By continuing, you agree to our Terms of Service and Privacy Policy.',
style: TextStyle(
fontSize: 14.0,
),
),
),
);
In this way the text doesn't overflow but I cannot make a part of text link. So I tried to use Row and separate the text and the link part as children.
However, the text overflows when I use Row and separate text as children.
How can I prevent them from overflowing while making a part of text link?
Use RichText class to link parts of text. It's constructor text.rich allows us to style different parts of the text. Below is the working code that only shows links for Terms of Service and Privacy Policy which user can tap on to open respective links and rest of the text is plain text:
Widget privacyPolicyLinkAndTermsOfService() {
return Container(
alignment: Alignment.center,
padding: EdgeInsets.all(10),
child: Center(
child: Text.rich(
TextSpan(
text: 'By continuing, you agree to our ', style: TextStyle(
fontSize: 16, color: Colors.black
),
children: <TextSpan>[
TextSpan(
text: 'Terms of Service', style: TextStyle(
fontSize: 16, color: Colors.black,
decoration: TextDecoration.underline,
),
recognizer: TapGestureRecognizer()
..onTap = () {
// code to open / launch terms of service link here
}
),
TextSpan(
text: ' and ', style: TextStyle(
fontSize: 18, color: Colors.black
),
children: <TextSpan>[
TextSpan(
text: 'Privacy Policy', style: TextStyle(
fontSize: 18, color: Colors.black,
decoration: TextDecoration.underline
),
recognizer: TapGestureRecognizer()
..onTap = () {
// code to open / launch privacy policy link here
}
)
]
)
]
)
)
),
);
}
Above code is rendered in UI as:
TapGestureRecognizer() method requires you to import below file:
import 'package:flutter/gestures.dart';
Hope this answers your question.
Using the TextStyle() class in Flutter, how can I strike through an old price?
To apply strikethrough decoration to a Text widget directly:
Text('\$8.99', style: TextStyle(decoration: TextDecoration.lineThrough))
You can also style separate spans of a paragraph by using the RichText widget, or the Text.rich() constructor.
Based on this example code, to show a discounted price:
RichText()
new RichText(
text: new TextSpan(
text: 'This item costs ',
children: <TextSpan>[
new TextSpan(
text: '\$8.99',
style: new TextStyle(
color: Colors.grey,
decoration: TextDecoration.lineThrough,
),
),
new TextSpan(
text: ' \$3.99',
),
],
),
)
Text.rich()
Text.rich(TextSpan(
text: 'This item costs ',
children: <TextSpan>[
new TextSpan(
text: '\$8.99',
style: new TextStyle(
color: Colors.grey,
decoration: TextDecoration.lineThrough,
),
),
new TextSpan(
text: ' \$3.99',
),
],
),
)
style: TextStyle(decoration: TextDecoration.lineThrough),
i use this
Column(
children: [
Text(
"sample text"
),
Divider(color: Colors.red,)
],
),
