vendorItemIndex property
The index into the DestinyVendorDefinition.itemList property. Note that this means Vendor data is Content Version dependent: make sure you have the latest content before you use Vendor data, or these indexes may mismatch. Most systems avoid this problem, but Vendors is one area where we are unable to reasonably avoid content dependency at the moment.
Implementation
@JsonKey(name:'vendorItemIndex')
int? vendorItemIndex;
