toString method

String toString ({dynamic color })
override

Returns a string representation of this.

color may either be a String, a bool, or null. If it's a string, it indicates an ANSII terminal color escape that should be used to highlight the span's text. If it's true, it indicates that the text should be highlighted using the default color. If it's false or null, it indicates that the text shouldn't be highlighted.

Implementation 

String toString({color}) {
  if (span == null) return message;
  return "Error on " + span.message(message, color: color);
}
