How to show Icon in Text widget in 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.

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))),
