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() => 'DeliveryStatusDto[id=$id, userId=$userId, sentId=$sentId, remoteMtaIp=$remoteMtaIp, inboxId=$inboxId, reportingMta=$reportingMta, recipients=$recipients, smtpResponse=$smtpResponse, smtpStatusCode=$smtpStatusCode, processingTimeMillis=$processingTimeMillis, received=$received, subject=$subject, createdAt=$createdAt, updatedAt=$updatedAt]';
