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 'PaymentInfo{secretKey: $secretKey, reference: $reference, companyAssetImage: $companyAssetImage, amount: $amount, country: $country, currency: $currency, email: $email, firstName: $firstName, lastName: $lastName, metadata: $metadata, paymentCard: $paymentCard}';
}
