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 'PassportModel('
'documentType: $documentType, '
'issuingCountry: $issuingCountry, '
'surname: $surname, '
'givenNames: $givenNames, '
'passportNumber: $passportNumber, '
'nationality: $nationality, '
'birthDate: $birthDate, '
'gender: $gender, '
'expiryDate: $expiryDate, '
'personalNumber: $personalNumber, '
'compositeCheckDigit: $compositeCheckDigit'
')';
}
