toString method Null safety

  1. @override
String toString(
  1. {dynamic color,
  2. String? secondaryColor}

Returns a string representation of this.

color may either be a String, a bool, or null. If it's a string, it indicates an ANSI terminal color escape that should be used to highlight the primary 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.

If color is true or a string, secondaryColor is used to highlight secondarySpans.


String toString({color, String? secondaryColor}) {
  if (span == null) return message;

  var useColor = false;
  String? primaryColor;
  if (color is String) {
    useColor = true;
    primaryColor = color;
  } else if (color == true) {
    useColor = true;

  final formatted = span!.messageMultiple(
      message, primaryLabel, secondarySpans,
      color: useColor,
      primaryColor: primaryColor,
      secondaryColor: secondaryColor);
  return 'Error on $formatted';
