  final defaultTextStyle = DefaultTextStyle.of(context).style;
  final scaleFactor = MediaQuery.of(context).textScaleFactor;

      painter: _WTextPainter(
        progress: _waveAnim.value,
        text: text,
        textStyle: defaultTextStyle.merge(textStyle),
        scaleFactor: scaleFactor,

            .merge(textStyle)
            .merge(TextStyle(color: Colors.transparent)),
