Set Text Widget style with method rather than constructor

Question

I'd like to be able to instantiate a Text Widget with many proprieties & create a new instance from it but with a new TextStlye by just calling a method on it like so :

  final Text myText = Text('hello', ...);

  final Text myTextWithNewStyle = myText.setNewStyle();

I thought of using an extension on Text but I'm not sure on how to keep all of it's current parameter values

You can update style like this if it works for you:

TextStyle defultStyle = TextStyle(color: Colors.red);
TextStyle newStyle = defultStyle.copyWith(color: Colors.blue)

or

extension TextExtension on Text {
  Widget setNewStyle(TextStyle newStyle, {Key key}) {
    return Text(this.data,
        key: key,
        style: newStyle,
        strutStyle: this.strutStyle,
        textAlign: this.textAlign,
        textDirection: this.textDirection,
        locale: this.locale,
        softWrap: this.softWrap,
        overflow: this.overflow,
        textScaleFactor: this.textScaleFactor,
        maxLines: this.maxLines,
        semanticsLabel: this.semanticsLabel,
        textWidthBasis: this.textWidthBasis,
        textHeightBehavior: this.textHeightBehavior);
  }
}

and use it like this:

Text text = Text(
      'dasdasd',
      style: TextStyle(color: Colors.blue),
    );
    Widget newText = text.setNewStyle(TextStyle(color: Colors.red));
