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() {
return 'QrCode(chassisNumber: $chassisNumber, engineNumber: $engineNumber, model: $model, color: $color, controlNumber: $controlNumber, id: $id, order: $order, signature: $signature, identifier: $identifier, purchaseOrderNumber: $purchaseOrderNumber, buyBackAmount: $buyBackAmount)';
}
