toString method

@override String toString()

A string representation of this object.

Some classes have a default textual representation, often paired with a static parse function (like int.parse). These classes will provide the textual representation as their string representation.

Other classes have no meaningful textual representation that a program will care about. Such classes will typically override toString to provide useful information when inspecting the object, mainly for debugging or logging.

Implementation

@override
String toString() {
  final sanitized = super.toString();
  // RFC2445 Section 4.1.1 requires parameter values
  // containing a COLON (:), SEMICOLON (;), or COMMA (,)
  // to be surrounded by double quotes
  return sanitized.contains(":") ||
          sanitized.contains(";") ||
          sanitized.contains(",")
      ? "\"$sanitized\""
      : sanitized;
}
