User Preference for 'per 100g' vs 'per serving' toggle

[zanovis]

Problem

In the US, nutrition facts are only provided 'per serving' which could be any number of grams/ounces/etc. It would be ideal to make a user preference for this, as I imagine it is largely region-dependent.

Proposed solution

Store this toggle as a shared_preference

Part of

• Nutrition Facts page -- per 100g <> per serving #3435

The 100g/serving switch value is either the one from the downloaded product, or with a default of 100g (for new products), cf. nutrition_container.dart:

    _initialPerSize = perSize =
        PerSize.fromOffTag(product.nutrimentDataPer) ?? PerSize.oneHundredGrams;

What you want is a new preference in order to change the default value for new products to "per serving", so that each time you input a new product, "per serving" would be selected, right?
I don't know if we should make that default value initially computed from the country, too.

@BhuvanAde As suggested, please add a user preference about the default "per 100g / per serving" and use it as default value in the nutrition fact page.

@monsieurtanuki I would like to work on this

to select the default value, should I add the toggle inside App Settings -> Products

@ooprathamm I'm already working on this issue.

@monsieurtanuki I'm so sorry forgot about this. I wasn't clear with the issue I see a similar type of issue #3617 are we moving forward with this issue?
Please confirm. And please let me know if there are any open issues.

[monsieurtanuki]

@BhuvanAde Please add the default switch 100g/serving in the preferences (default 100g), and use it as default in the nutrition page.

@BhuvanAde Still working on it, or may we reassign this issue?
