[Feature] - Scale text extension

[Massimo Caroccia]

Hi, can you add this extensions to scale text with factor?

Widget noTextScale(BuildContext context) {
    return this.scaleText(context, scaleFactor: 1.0);
  }

  Widget scaleText(BuildContext context, {required double scaleFactor}) {
    return MediaQuery(
      data: MediaQuery.of(context).copyWith(textScaleFactor: scaleFactor),
      child: this,
    );
  }
