generatedAt property
GeneratedAt is when the bundle was assembled — the moment the statements were struck, which is what makes two exports of the same period comparable.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
Implementation
String? generatedAt;
