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 kind = isInsert
      ? 'insert'
      : isRemove
          ? 'remove'
          : 'set';
  return '#<MapChangeRecord $kind $key from $oldValue to $newValue>';
}
