A value of type 'TextSpan' can't be returned from the method 'build' because it has a return type of 'Widget'

I need to create a custom SpanText, but i found this issue.
A value of type ‘TextSpan’ can’t be returned from the method ‘build’ because it has a return type of ‘Widget’.

The Code Is:

class StareWidget extends StatelessWidget {
  const StareWidget({Key? key, required this.text}) : super(key: key);
  final String text;
  @override
  Widget build(BuildContext context) {
    return TextSpan();
  }
}

>Solution :

According to documentation

To paint a TextSpan on a Canvas, use a TextPainter. To display a text span in a widget, use a RichText. For text with a single style, consider using the Text widget.

So your TextSpan needs to have a RichText as parent.
