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() {
  final StringBuffer buffer = StringBuffer("CorruptTokenDataException");

  if (message != null) {
    buffer.write(": $message");
  }

  if (value != null) {
    buffer.write('\n'
        '\tExpected: {"${ApiFields.accessToken}": [access_token], '
        '"${ApiFields.expiresIn}": [seconds], "${ApiFields.expirationDate}": '
        '[date], "${ApiFields.refreshToken}": [refresh_token], '
        '"${ApiFields.tokenType}": "bearer"}\n'
        '\tActual: ${value.toString()}');
  }

  return buffer.toString();
}
