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 out = StringBuffer(
      'DVAppKeyStoreUnavailable: $store cannot hold the application key: '
      '$reason');
  if (status != null) out.write(' (status $status)');
  if (cause != null) out.write(' ($cause)');
  return out.toString();
}
