Ingredients and Stores cannot be presented in a list

[AdrienMDevMobile]

This issue is blocking #5814
Ideally, to present values in a list of elements, the values need to be given to the app in a list.

That is not the case for Ingredients and stores.The list values IngredientsTagsInLanguage and storeTagsInLanguage are null.
The list of ingredients and stores are found in a single String
This can be found in the nutella page, but also this butter and this juice : https://world.openfoodfacts.org/product/3451790988677/le-beurre-tendre-doux-elle-vire
https://world.openfoodfacts.org/product/3254691586054/le-bio-pour-toute-la-famille-multifruit-pressade

Here are two solutions : correct the serverside answer to give the elements in a listvalue in the request.
or : adapt the code of the rawdata list to have the Strings be broken down into a list.

Solution 2 is the easiest to do, but will create technical dept.

• This looks very much like a server bug @stephanegigandet @alexgarel

For the stores, you can have a look at what's done on the Edit page.
SimpleInputPageStoreHelper.dart:

splitString(product.stores);

And for the ingredients, you can do the same.
Clearly, a server-side fix would be better.
But it seems that the code for stores is here for months.

@teolemon the right request for ingredient, eg for french, is: https://world.openfoodfacts.org/api/v1/product/3451790988677.json?fields=ingredients_tags_fr

[alexgarel]

For stores https://world.openfoodfacts.org/api/v1/product/3451790988677.json?fields=stores_tags

I am currently using ingredientsTextInLanguages, other field 'ingredient' is null Ingredients tag fr is not present in the Product class

For stores, I am currently using stores. I have an issue with StoresInLanguage ; the english value is currently null (despite stores field beeing filled with english stores data)

[AdrienMDevMobile]

The product class contains nutrition values but not their metrics (kJ, kcal...)
I wasn't able to find it in the code, but I assume when clicking the nutrition on the product screen it does a web call.

Shoudl I do this web call on my view ? or the product class should contain the metrics ?
