@override
Widget build(BuildContext context) => Text(
separator != null
? '$prefix${animation.value.toStringAsFixed(precision).replaceAllMapped(reg, (Match match) => '${match[1]}'
'$separator')}$suffix'
: '$prefix${animation.value.toStringAsFixed(precision)}$suffix',
style: style,
textAlign: textAlign,
textDirection: textDirection,
locale: locale,
softWrap: softWrap,
overflow: overflow,
textScaler: textScaleFactor == null ? null : TextScaler.linear(textScaleFactor!),
maxLines: maxLines,
semanticsLabel: semanticsLabel,
);
