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 status = isSafe
      ? 'SAFE'
      : isDefinitelyNull
          ? 'NULL'
          : 'UNKNOWN';
  return 'NullCheck[$status]: ${dereference.variable} - $reason';
}
