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 'Promissory{version: $version, signatureSystem: $signatureSystem, id: $id, currencyCode: $currencyCode, amount: $amount, decimals: $decimals, authority: $authority, issuer: $issuer, issuanceDate: $issuanceDate, authorizedSignature: $authorizedSignature, securedSignature: $securedSignature, signatureBlock: $signatureBlock, blockDepth: $blockDepth}';
}
