toString method

  1. @override
String toString()
override

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() {
  String msg = '\nResult: isSuccess: $isSuccess\n';
  msg += '\n';
  if (data != null) {
    msg += data?.toString() ?? '';
  }
  if (error != null) {
    msg += error?.toString() ?? '';
  }
  return msg;
}
