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 (httpStatusCode == 200) {
    return 'Access Token: ' + (accessToken ?? 'n.a.');
  } else {
    return 'HTTP ' +
        httpStatusCode.toString() +
        ' - ' +
        (error ?? '') +
        ' ' +
        (errorDescription ?? '');
  }
}
