How to show Icon in Text widget in flutter?
FlutterFlutter Problem Overview
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 Solutions
Solution 1 - Flutter
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.
Solution 2 - Flutter
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
Solution 3 - Flutter
Screenshot:
-
UsingWrap
:Wrap( crossAxisAlignment: WrapCrossAlignment.center, children: [ Text('Click'), Icon(Icons.add), Text('to add'), ], )
-
UsingRow
:Row( mainAxisSize: MainAxisSize.min, children: [ Text('Click'), Icon(Icons.add), Text('to add'), ], )
-
UsingText.rich
:Text.rich( TextSpan( children: [ TextSpan(text: 'Click'), WidgetSpan(child: Icon(Icons.add)), TextSpan(text: 'to add'), ], ), )
Solution 4 - Flutter
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")
]
)
Solution 5 - Flutter
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 :
Solution 6 - Flutter
You can use WidgetSpan() on Text.rich(). Here's a link for InlineSpan-class.
Solution 7 - Flutter
I think it's better to use the Row widget. here is an example
Row(
children: [
Icon(Icons.download_rounded),
Text(" Download")
],
)
Solution 8 - Flutter
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.
