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() => 'Card[id=$id, created=$created, modified=$modified, deletedAt=$deletedAt, stripeToken=$stripeToken, stripeId=$stripeId, last4=$last4, brand=$brand, country=$country, expMonth=$expMonth, expYear=$expYear, isDefault=$isDefault, isActive=$isActive, user=$user]';
