groupedCategoryHashes property

  1. @JsonKey(name: 'groupedCategoryHashes')
List<int>? groupedCategoryHashes
getter/setter pair

If this category is a "parent" category of other categories, those children will have their hashes listed in rendering order here, and can be looked up using these hashes against DestinyItemCategoryDefinition. In this way, you can build up a visual hierarchy of item categories. That's what we did, and you can do it too. I believe in you. Yes, you, Carl. (I hope someone named Carl reads this someday)

Implementation

@JsonKey(name:'groupedCategoryHashes')
List<int>? groupedCategoryHashes;
