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() => 'Assertions[id=$id, user=$user, created=$created, updated=$updated, entityId=$entityId, credential=$credential, metadata=$metadata, issuedOn=$issuedOn, revoked=$revoked, revocationReason=$revocationReason, expiresAt=$expiresAt, hashed=$hashed, salt=$salt, narrative=$narrative, acceptance=$acceptance, item=$item]';
