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() {
  String value = """
ShellConversionException: could not convert to '$to' from '$from'
  """;
  if (addtionalMessage != null) {
    value += """

$addtionalMessage
    """;
  }
  return value;
}
