Question

i want to show a superscript text but not found any example or can anyone help me with this.

I have tried Text and RichText also, but not found any method or fields.

You can make use of offset property in WidgetSpan. I have used the below code to show flight cross overs. The Offset dx and dy values helps you to set superscript or subscript as per your need.

RichText(
  text: TextSpan(children: [
    TextSpan(
        text: '9:30 - 2:30',
        style: TextStyle(color: Colors.black)),
    WidgetSpan(
      child: Transform.translate(
        offset: const Offset(2, -4),
        child: Text(
          '+2',
          //superscript is usually smaller in size
          textScaleFactor: 0.7,
          style: TextStyle(color: Colors.red),
        ),
      ),
    )
  ]),
)
