ratingHistogram property

List<int>? ratingHistogram

List of rating counts per rating value (index = rating - 1).

The list is empty if there is no rating. If the list is non-empty, its size is always 5. Otherwise, an INVALID_ARGUMENT error is returned. For example, [41, 14, 13, 47, 303]. It means that the Product got 41 ratings with 1 star, 14 ratings with 2 star, and so on.
