TextPainter({
  TextSpan text,
  TextAlign textAlign = TextAlign.start,
  TextDirection textDirection,
  double textScaleFactor = 1.0,
  int maxLines,
  String ellipsis,
  Locale locale,
}) : assert(text == null || text.debugAssertIsValid()),
     assert(textAlign != null),
     assert(textScaleFactor != null),
     assert(maxLines == null || maxLines > 0),
     _text = text,
     _textAlign = textAlign,
     _textDirection = textDirection,
     _textScaleFactor = textScaleFactor,
     _maxLines = maxLines,
     _ellipsis = ellipsis,
