toString method
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() => 'Credential[id=$id, created=$created, updated=$updated, entityId=$entityId, name=$name, items=$items, description=$description, criteriaUrl=$criteriaUrl, criteriaText=$criteriaText, expiresAmount=$expiresAmount, expiresDuration=$expiresDuration, iconImage=$iconImage, thumbnailImage=$thumbnailImage, backgroundImage=$backgroundImage, credentialType=$credentialType, tags=$tags, public=$public, metadata=$metadata, htmlTemplate=$htmlTemplate, cssTemplate=$cssTemplate, issuingSignal=$issuingSignal, issuer=$issuer]';
