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 {
'billing_ide': billingIde,
'bill_number': billNumber,
'mobile_number': mobileNumber,
'store_label': storeLabel,
'loyalty_number': loyaltyNumber,
'reference_label': referenceLabel,
'customer_label': customerLabel,
'terminal_label': terminalLabel,
'purpose_of_transaction': purposeOfTransaction,
'additional_consumer_data': additionalConsumerData,
'merchant_tax_id': merchantTaxId,
'merchant_channel': merchantChannel,
'extra_data': extraData,
}.toPrettyString();
