toString method Null safety

  1. @override
String toString()
override

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() {
  var label = severity == JaelErrorSeverity.warning ? 'warning' : 'error';
  return '$label: ${span.start.toolString}: $message\n' +
      span.highlight(color: true);
}
