openfoodfacts 0.3.15+2

Dart package for the Open Food Facts API, a food products database made by everyone, for everyone.

Open Food Facts - Dart

Dart package for the Open Food Facts API. Easily access to more than 1.5 million products from all around the world. Open Food Facts is powered by global contributors and is constantly growing thanks to them.

General principles

• 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.

If your users do expect a result immediately (eg. Inventory apps)

• Send photos (front/nutrition/ingredients): 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

If your users expect a result immediately:

• Send nutrition facts + category > get Nutri-Score
• Send ingredients > get the NOVA group (about food ultra-processing), additives, allergens, normalized ingredients, vegan, vegetarian…
• Send category + labels > get soon the Eco-Score (about environmental impact)
