Implementation

const Text.rich(
  InlineSpan this.textSpan, {
  Key? key,
  this.style,
  this.strutStyle,
  this.textAlign,
  this.textDirection,
  this.locale,
  this.softWrap,
  this.overflow,
  this.textScaleFactor,
  this.maxLines,
  this.semanticsLabel,
  this.textWidthBasis,
  this.textHeightBehavior,
}) : assert(
       textSpan != null,
       'A non-null TextSpan must be provided to a Text.rich widget.',
     ),
     data = null,
     super(key: key);
