You can find the full documentation here: Documentation. You can find automated code documentation here: Documentation.

• You can look for information about products, including many useful computed values.
• If you can't get the information on a specific product, you can get your user to send photos and data, that will then be processed by Open Food Facts AI and contributors to get the computed result you want to show them.
• You can also implement the complete flow so that they get immediately the result with some effort on their side.

• Now the only entry point is import 'package:openfoodfacts/openfoodfacts.dart';
  • replace all your instances of import 'package:openfoodfacts/...'; with a single import 'package:openfoodfacts/openfoodfacts.dart';
• If you used State from product_state.dart, you have to rename it to ProductState
• If you used Level from nutrient_levels.dart, you have to rename it to NutrientLevel
• Removed deprecated classes:
  • Page
  • ProductListQueryConfiguration
  • ToBeCompletedConfiguration
• Removed deprecated fields and methods in Nutriments
  • all the single nutrient value fields were removed - use getValue and setValue instead
  • instead of getUnit use nutrient.typicalUnit

• Send photos (front/nutrition/ingredients/packaging): most painless thing for your users
• The Open Food Facts AI Robotoff will generate some derived data from the photos
• Overtime, other apps, and the Open Food Facts community will fill the data gaps

• Send nutrition facts + category > get the Nutri-Score
• Send ingredients > get the NOVA group (about food ultra-processing), additives, allergens, normalized ingredients, vegan, vegetarian…
• Send category (strict minimum) + labels + origins of ingredients + packaging (photo and text) > get the Eco-Score (about environmental impact)
