toString method Null safety

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

String toString() => '[NullValRef ' //
    'id: ${id}, kind: ${kind}, identityHashCode: ${identityHashCode}, ' //
    'classRef: ${classRef}, valueAsString: ${valueAsString}]';
