Firebase Analytics does not show AnalyticsEventItem

In a Flutter application, I'm trying to track some user activities. The app uses GoogleAnalytics and some Firebase features. Thus it uses Firebase Analytics to measure statistics.

For example, I would like to see which item (product) added wishlist mostly. So I wrote this code to track if user add a specific item to their wishlist:

 Future<void> addToWishlist({ required int productId, required String name, required int brandId, required int categoryId, required double price, }) async { var analyticsEventItem = AnalyticsEventItem( itemId: productId.toString(), itemName: name, itemBrand: brandId.toString(), itemCategory: categoryId.toString(), ); await FirebaseAnalytics.instance.logAddToWishlist( value: price, currency: "USD", items: [analyticsEventItem], ); } 

In dashboard, it shows value and currency correctly but I could not find any item under add_to_wishlist event.

Is there something wrong I did? Where can I see these items?
