parents property

List<String>? parents
getter/setter pair

Parents of the origin (like, France is the parent of Aquitaine).

In real life the field is rarely populated, or with only one parent. Stats on 2022-11-06: 81/369 origins have children. Don't expect too much relevancy - tree-wise - as France and Europe are both root origins, and Europe is not the parent of France.

Implementation

@JsonKey(includeIfNull: false)
List<String>? parents;
