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 'LineItem(id: $id, categoryId: $categoryId, name: $name, description: $description, quantity: $quantity, gtin: $gtin, imageUrl: $imageUrl, brand: $brand, externalItemId: $externalItemId, itemAmount: $itemAmount)';
}
