toString method

@override String toString()

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() {
  var string = '';
  string += cnicNumber.isEmpty ? "" : 'Cnic Number = $cnicNumber\n';
  string +=
      cnicExpiryDate.isEmpty ? "" : 'Cnic Expiry Date = $cnicExpiryDate\n';
  string += cnicIssueDate.isEmpty ? "" : 'Cnic Issue Date = $cnicIssueDate\n';
  string +=
      cnicHolderName.isEmpty ? "" : 'Cnic Holder Name = $cnicHolderName\n';
  string += cnicHolderDateOfBirth.isEmpty
      ? ""
      : 'Cnic Holder DoB = $cnicHolderDateOfBirth\n';
  return string;
}
