feat: 5430 - "producer provided" icon for nutrients and 4 product fields

[monsieurtanuki]

What

• Adds an icon for each field or nutrient that was provided by the producer.
• So far, the impacted field list is product name, brands, quantity and serving size.
• We can add the icon to other fields, but even on the website it doesn't seem to be systematic (e.g. category for 7300400481588 is "producer provided" but that doesn't show on the website)

We should probably make the icon clickable with a possibility to understand what it's about and possibly to complain or email/file a ticket on Nutri-Patrol if they believe there's a data mistake.

@teolemon Makes almost sense.
In the current PR I added a suffix icon to the text field - this UI option is supported by flutter.
Displaying a separate icon would break a little the display, why not.
But that would look preposterous for the nutrition facts page: an additional icon button on each already crowded nutrient line that always says the same thing.

What could be done instead from the current PR is adding an expandable line (e.g. a ListTile) with the same icon and a "Producer provided - what does it mean" text + link.
And we can display this line only once per page and only for pages that do have at least one producer provided data.
What do you think of that?

[teolemon]

sounds reasonable

[monsieurtanuki]

@teolemon Just added a standard info tile about "owner fields" when relevant. Should that be clickable? Is the text explicit enough?

• Can we have the same mechanism for Producer provided photos ? do we have the necessary info ?
• Should we have a link to mailto:producers@openfoodfacts.org or a nutripatrol report link https://nutripatrol.openfoodfacts.org/flag/product?barcode=3017620422003&source=web&flavor=off ?

Doesn't look like we have that kind of information in owner fields: https://fr.openfoodfacts.org/api/v3/product/7300400481588?fields=owner_fields
Any product you're thinking of?

Should we have a link to mailto:producers@openfoodfacts.org or a nutripatrol report link https://nutripatrol.openfoodfacts.org/flag/product?barcode=3017620422003&source=web&flavor=off ?

With the current solution we don't have too much space. A click on the info tile could open a dialog or even a page with more explanations. And a button to that email and another to that report link.

Generally speaking, seems OK for me.
Could you add some Semantics for screen readers?

Sure, I'll do that the next time I code for this PR.

[teolemon]

@monsieurtanuki thanks for this addition

[monsieurtanuki]

Thank you @teolemon for your review!

I just have to add a Semantics and we're OK.
