Overview

Open Food Facts - Codename: "Smooth App"

A new Flutter application by Open Food Facts. You can install it on Android or iPhone/iPad. Note that a internal development build if you'd like to use the results of your PRs quicker.

Smoothie. We pioneered the collaborative scanning app in 2012. With this experimental app, we’re reinventing it from the ground up, and this time, it’s personal.

You get:

  • a scan that truly matches who you are (Green: the product matches your criteria, Red: there is a problem, Gray: Help us answer you by photographing the products)
  • a product page that's knowledgeable, building on the vast amount of food facts we collect collaboratively, and other sources of knowledge, to help you make better food decisions

You can:

  • scan and compare in 15 seconds the 3 brands of tomato sauces left on the shelf, on your terms.
  • get a tailored comparison of any food category
  • set your preferences without ruining your privacy

Criteria you can pick:

  • Environment: Eco-Score
  • Health: Additives & Ultra processed foods, Salt, Allergens, Nutri-Score

Presentation

This new mobile application aims to showcase Open Food Facts's power to a broad range of users through a smooth user experience and sleek user interface.

Smooth-app is developed in parallel to the openfoodfacts-dart plugin, which provides a high level interface with the Open Food Facts API. Every new interaction with the API should be implemented in the plugin in order to provide these new features to other developers.

    • summary_card.dart: new way to have a product changed
    • up_to_date_product_provider.dart: heavily refactored

    What

    • The management of "instant local changes" and "pending background tasks" has been rethought.
    • That would probably deserve some explanations.I'd be glad to write something, probably in the code, probably in UpToDatProductProvider- feel free to ask anything.
    • Possible issues:
      • I focused on "background task details", as I'm not very familiar with image upload: tests are definitely needed there.
      • For the moment I lazily stored the "instant local changes" in dart Maps - I'll switch to persistent storage like hive or sqflite after this PR is merged (let me time to breathe first!)
      • For the moment the task key system won't work when we have several tasks pending on the same subject (e.g. categories), and that needs to be fixed (or double-checked)
    • Cool (?) future features:
      • Now we're able to know on a product page if it has pending changes. I had the idea to display that state (in a clumsy way), as a feedback to the user ("not uploaded yet!"), for the moment on the "edit product page" (cf. screenshots)
      • If this idea is deemed "cool", we have to decide on which page to display that state, and how.

    Screenshot

    I've just left the shop page that I edited

    • I can see a (*) before the name of the product (= "not all changes are uploaded yet")
    • there's a snackbar

    We have a BIG scan issue

    What

    We have a big scan issue. We discussed it at length with @g123k the other day. I'm pinning this until we solve it, and people are happy again.

    People are complaining on all channels (email, appstore, app survey)

    I believe we didn't ship some of the fixes in the last release, so native bug is still on-going, and people are still complaining: https://github.com/openfoodfacts/smooth-app/pull/2740/files#diff-5898cc81afbf2560f009273208f7247c03d829eabc864ab252c5ef475a713f5eR151

    Complaints are focused on Redmi, Oppo, Oneplus

    Here's raw user feedback if you'd like to peruse, Scan issues are classified as such: https://docs.google.com/spreadsheets/d/1KsJv8_RxfDDd5ngmeQ4k8ELsudl-YhleXEoDFoGoSAE/edit#gid=1439550856

    Linked issues

    • https://github.com/openfoodfacts/smooth-app/issues/2742 We pinpointed this with @g123k. It's probably not the whole story, but might be contributing to it

    • We might want to explore an isolate as well since people have been complaining about the app freezing

    • #2381 We might want to explore the new camerax plugin to benefit from whatever little compat gains they did. There's a new plugin in town that might be worth exploring

  • Question: when is the list of products in

    Question: when is the list of products in "Scan and compare products" reinitialized?

    I cannot find a way to clear the list of products in my "Scan and compare products" list, or to remove items from it. Is it possible somewhere?

    Maybe we could:

    1. add a way to start a new comparison (a "Clear list" button on the left of the "My personal ranking" button in the scanning page?)

    2. in the "My personal ranking" list, be able to swipe to remove entries?

    What do you think?

  • feat: image list gallery

    feat: image list gallery

    In V1 (at least for android) we had a "Image gallery" page which would display the list of every image related to the product.

    Here we have the carousel that gets activated whenever you click on the images (or click on edit images in the edit view) but it's not really a listing of every image related to the product.

    That's why, as suggested by @teolemon, with this PR I'm implementing a product image gallery view as a list of clickable items. When a tile is clicked the corresponding image is opened (if existing) to be viewed/edited, or taken.

    Below a video representing the flow:

  • Background + offline incoherences on multiple offline edits

    Background + offline incoherences on multiple offline edits

    What

    Assuming that I use the app offline and that I change a product 5 times in a row (changes A, B, C, D and E), there are 5 background processes pending, all on the same product.

    When I go online, I may have problems.

    • Problem 1: if each process is executed atomically in a queue, after I run processes about A and B, I'll get the server product with changes A and B, but not yet C, D and E. The product is less complete than when I was offline with all my changes.
      • Solution 1: merge all changes about the same product into a single background process before executing it.
    • Problem 2: if I try to refresh the product before the background processes are executed, I'll get a fresh product from the server but without my local changes.
      • Solution 2: we should not be able to refresh a product when there are pending background processes. In addition to that, we could add an icon "local changes pending" and an error message "cannot refresh product while there are local changes pending".
    • Problem 3, related to problem 1 (spoiler alert: bad luck problem): if while the merged background processes are executed I change the product (change "F"), after the execution I get a fresh server product with all my initial changes (A-E), but change F will be ignored, until background process about F is executed.
      • Solution 3: each time we get product data from the server, we have to apply the pending changes before storing it locally.

    The more I think about it, the more I believe that solution 3 would solve everything (we wouldn't need solutions 1 and 2).

    @AshAman999 Do you share my views?

    Various issues with the iOS build

    Dear Developer,

    We identified one or more issues with a recent delivery for your app, "Open Food Facts +" 5.5.5 (16). Please correct the following issues, then upload again.

    ITMS-90683: Missing Purpose String in Info.plist - Your app's code references one or more APIs that access sensitive user data. The app's Info.plist file should contain a NSPhotoLibraryUsageDescription key with a user-facing purpose string explaining clearly and completely why your app needs the data. Starting Spring 2019, all apps submitted to the App Store that access user data are required to include a purpose string. If you're using external libraries or SDKs, they may reference APIs that require a purpose string. While your app might not use these APIs, a purpose string is still required. You can contact the developer of the library or SDK and request they release a version of their code that doesn't contain the APIs. Learn more (https://developer.apple.com/documentation/uikit/core_app/protecting_the_user_s_privacy).

    ITMS-90809: Deprecated API Usage - New apps that use UIWebView are no longer accepted. Instead, use WKWebView for improved security and reliability. Learn more (https://developer.apple.com/documentation/uikit/uiwebview).

    Though you are not required to fix the following issues, we wanted to make you aware of them:

    ITMS-90078: Missing Push Notification Entitlement - Your app appears to register with the Apple Push Notification service, but the app signature's entitlements do not include the 'aps-environment' entitlement. If your app uses the Apple Push Notification service, make sure your App ID is enabled for Push Notification in the Provisioning Portal, and resubmit after signing your app with a Distribution provisioning profile that includes the 'aps-environment' entitlement. Xcode does not automatically copy the aps-environment entitlement from provisioning profiles at build time. This behavior is intentional. To use this entitlement, either enable Push Notifications in the project editor's Capabilities pane, or manually add the entitlement to your entitlements file. For more information, see https://developer.apple.com/library/content/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/HandlingRemoteNotifications.html#//apple_ref/doc/uid/TP40008194-CH6-SW1.

    refactor: ProductImageData to contain all image links

    What

    Improve product image quality for some pages. For example, when full screen image viewer is open (please see issue description).

    My idea was to refactor ProductImageData to contain a Map of all product images for every image size, so you can get specific image quality you want, when you need it.

    I'm submitting this as draft for now, since I'm not completely sure if that is the best approach. Open to ideas. Maybe better backend support would be needed.

    Simplify adding photos by removing 2 of the 4 steps

    Current behaviour:

    1. Screen to take a photo
    2. OK / Retry dialog (not sure if that's the app or the camera, hopefully we can disable it in any case..)
    3. Crop interface
    4. Retry / Edit / Confirm dialog

    Suggestion:

    Merge 2. 3. and 4. into a single Crop interface (same as today's + a Retry button). I don't think we need an extra confirmation step, we can submit the image as soon as the user hits "ok" on the crop screen.

    Authentication using google and apple.

    Problem

    Currently, the app only accepts email sign-in/signup. Having OAuth would be better for the user as they can sign in with ease.

    Proposed solution

    We can create a google and apple OAuth depending on the platform at the login-page.

    Additional context

    We can implement this feature using google_sign_in and apple_sign_in packages from pub dev along with the firebase. We can do this using flutter_appauth as well.

    But I need to understand the backend first to implement this feature because if the user is existing then we won't direct him to the signup page for asking for their username and other mandatory processes.

    • We care about that because we care about the order of the changes
      • if we know 2 tasks are similar, we know we can get rid of the former, as it will be overwritten anyway by the latter.
      • It's not just a matter of being quicker by getting rid of "useless" tasks, it's a matter of not having to worry about if task A is run after task B.
      • it's also a matter of "ok this task failed, but the other tasks are not related, so we can run them anyway"
