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() {
  if (isSuccess) {
    return 'Success(data: $data)';
  } else {
    final swString = (sw1 != null && sw2 != null)
        ? ', SW: ${sw1!.toRadixString(16).padLeft(2, '0')}${sw2!.toRadixString(16).padLeft(2, '0')}'
        : '';
    return 'Failure(status: $status, message: "$message"$swString)';
  }
}
