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() {
  return '{root: $root,'
      ' length: $length,'
      ' purgedLength: $purgedLength,'
      ' purgedEntriesCount: $purgedEntriesCount,'
      ' revalidatedPurgedEntries: $revalidatedPurgedEntriesCount,'
      ' keepPurgedEntries: $keepPurgedEntries,'
      ' purgedEntriesTimeout: ${purgedEntriesTimeout?.inMilliseconds ?? -1}ms,'
      ' maxPurgedEntries: $maxPurgedEntries}';
}
