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 (StringBuffer('SalesOrderData(')
..write('id: $id, ')
..write('orderDateTime: $orderDateTime, ')
..write('amount: $amount, ')
..write('taxAmount: $taxAmount, ')
..write('status: $status, ')
..write('sellerId: $sellerId, ')
..write('customerId: $customerId')
..write(')'))
.toString();
}
