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 metadataStr = metadata != null ? ', metadata: $metadata' : '';
  return 'Snapshot('
      'timestamp: $timestamp, '
      'appVersion: $appVersion, '
      'schemaVersion: $schemaVersion, '
      'states: ${states.keys.toList()}$metadataStr)';
}
