nutrition_ai 3.2.3

Passio Nutrition AI SDK for Flutter. Supports Android and iOS.

3.2.3

Added APIs

• Added a new search function that provides contextually connected items to the search term:

Future<PassioSearchResponse> searchForFoodSemantic(String term) async {
  return NutritionAIPlatform.instance.searchForFoodSemantic(term);
}

• Added a new api for a recipe builder feature, that gives a list of predicted next ingredients based on the current list of ingredients in the recipe:

Future<List<PassioFoodDataInfo>> predictNextIngredients(List<String> currentIngredients) async {
  return NutritionAIPlatform.instance.predictNextIngredients(currentIngredients);
}

Refactored APIs

• Refactored PassioNutritionFacts: renamed servingSizeQuantity to servingQuantity and servingSizeUnitName to servingUnit; removed servingSize; added weightQuantity and weightUnit.
• Refactored fetchTagsFor and fetchInflammatoryEffectData to accept refCode as a parameter instead of passioID.

Deprecated APIs

• detectFoodIn has been removed.

3.2.1+1

• Fixed Android build issues for smoother project setup.

3.2.1

⚠️ Breaking Changes

• Configuration for Android is no longer required. Please remove any code related to finding the AAR file from your top build.gradle file (Project: android).

Refactored APIs

• The fetchFoodItemForDataInfo method now includes optional servingQuantity and servingUnit parameters to provide details based on the specified serving size:

Future<PassioFoodItem?> fetchFoodItemForDataInfo(PassioFoodDataInfo passioFoodDataInfo, {double? servingQuantity, String? servingUnit})

Added APIs

• Added the reportFoodItem function to report incorrect food items:

Future<PassioResult<bool>> reportFoodItem({String refCode = '', String productCode = '', List<String>? notes})

• Added the submitUserCreatedFood function to submit user-created food items:

Future<PassioResult<bool>> submitUserCreatedFood(PassioFoodItem item)

3.2.0+1

Fixed

• Resolved an issue with the iOS build process that was causing build failures in certain environments.

3.2.0+1

Fixed

• Resolved an issue with the iOS build process that was causing build failures in certain environments.

3.2.0

Added APIs

• Added function recognizeNutritionFactsRemote that can parse the nutrition facts table from an image and return a PassioFoodItem with the scanned nutrients

Future<PassioFoodItem?> recognizeNutritionFactsRemote(Uint8List bytes, {PassioImageResolution resolution = PassioImageResolution.res_1080})

• Added support for localized content. Using updateLanguage with a two digit ISO 639-1 language code will transform the food names and serving sizes in the SDK responses.

Future<bool> updateLanguage(String languageCode)

• Added remoteOnly flag to the PassioConfiguration class. With this flag enabled, the SDK won't download the files needed for local recognition. In this case only remote recognition is possible.

class PassioConfiguration{
  ...
  final bool remoteOnly;
}

Refactored APIs

• recognizeImageRemote can now scan barcodes and nutrition facts. The PassioAdvisorFoodInfo class has been augmented to handle these responses

class PassioAdvisorFoodInfo {
  final PassioFoodDataInfo? foodDataInfo;
  final PassioFoodItem? packagedFoodItem;
  final String portionSize;
  final PassioFoodResultType resultType;
  final String recognisedName;
  final double weightGrams;
}

enum PassioFoodResultType {
  foodItem,
  barcode,
  nutritionFacts,
}

• Property tags was added to PassioFoodDataInfo

class PassioFoodDataInfo {
    ...
    final List<String>? tags;
}

• Vitamin A RAE was added to the PassioNutrients class.

class PassioNutrients {
  ...
  final UnitMass? _vitaminARAE;
}

3.1.4+2

• Improved scanning performance on Android

3.1.4+1

Added APIs

• Added fiber value to PassioSearchNutritionPreview

3.1.4

Added APIs

• With the new key comes the new pricing model using tokens. Although all token usage can be seen in the portal, the SDK itself offers a listener to count the tokens being used by the SDK.

void setAccountListener(PassioAccountListener? listener)

abstract interface class PassioAccountListener {
    void onTokenBudgetUpdate(PassioTokenBudget tokenBudget);
}

class PassioTokenBudget {
    final String apiName;
    final int budgetCap;
    final int periodUsage;
    final int tokensUsed;
}

• Control Flashlight: Manage the flashlight with:

/// [enabled] A required parameter to turn the flashlight on or off.
/// [level] An optional parameter specifying the intensity level of the flashlight, with a default value of 1. Note that the level parameter is only applicable on iOS for now.
Future<void> enableFlashlight({required bool enabled, double level = 1})

• Get Camera Zoom Levels: Retrieve the minimum and maximum zoom levels with:

Future<PassioCameraZoomLevel> getMinMaxCameraZoomLevel()

class PassioCameraZoomLevel {
  final double? minZoomLevel;
  final double? maxZoomLevel;
}

• Set Camera Zoom Level: Adjust the camera zoom level:

/// [zoomLevel] Sets the desired zoom level. Ensure it’s within the range obtained from ```getMinMaxCameraZoomLevel()```.
Future<void> setCameraZoomLevel({required double zoomLevel})

Refactored APIs

• Updated the fetchFoodItemForDataInfo method to include an optional weightGrams parameter:

/// [weightGrams] An optional parameter that provides information specific to the specified weight in grams.
Future<PassioFoodItem?> fetchFoodItemForDataInfo(PassioFoodDataInfo passioFoodDataInfo,{double? weightGrams})

• The NutritionAdvisor no longer needs a separate key for configuration. The PassioSDK needs to be configured in order to call the NutritionAdvisor APIs. Also, any previous NutritionAdvisor keys won't work with this version, a new key needs to be obtained at https://www.passio.ai/

3.1.1

Added APIs

• Added PassioImageResolution resolution as a parameter of the recognizeImageRemote function. This enables the caller to set the target resolution of the image uploaded to the server. Smaller resolutions will result in faster response times, while higher resolutions should provide more accurate results.

enum PassioImageResolution {
  res_512,
  res_1080,
  full,
}

• Added a function to retrieve possible hidden ingredients for a given food name.

Future<PassioResult<List<PassioAdvisorFoodInfo>>> fetchHiddenIngredients(String foodName)

• Added a function to retrieve possible visual alternatives for a given food name.

Future<PassioResult<List<PassioAdvisorFoodInfo>>> fetchVisualAlternatives(String foodName)

• Added a function to retrieve possible ingredients if a more complex food for a given food name.

Future<PassioResult<List<PassioAdvisorFoodInfo>>> fetchPossibleIngredients(String foodName)

3.1.0

New Features

Nutrition AI Advisor

• To access the API of the Advisor use NutritionAdvisor.instance
• The method Future<PassioResult<PassioAdvisorResponse>> fetchIngredients(PassioAdvisorResponse response) works only with the response from sendMessage(). It returns data if the PassioAdvisorResponse contains tools.

Future<PassioResult> configure(String key)

Future<PassioResult> initConversation()

Future<PassioResult<PassioAdvisorResponse>> sendMessage(String message)

Future<PassioResult<PassioAdvisorResponse>> sendImage(Uint8List bytes)

Future<PassioResult<PassioAdvisorResponse>> fetchIngredients(PassioAdvisorResponse response)

Nutrition Facts Detection

void startNutritionFactsDetection(NutritionFactsRecognitionListener listener)

Future<void> stopNutritionFactsDetection()

abstract interface class NutritionFactsRecognitionListener {
  void onNutritionFactsRecognized(PassioNutritionFacts? nutritionFacts, String? text);
}

Refactored APIs

• The FoodDetectionConfiguration object no longer has the detectNutritionFacts parameter.

Added APIs

• Added speech recognition API that retrieves a list of recognized foods from the input text query.

Future<List<PassioSpeechRecognitionModel>> recognizeSpeechRemote(String text)

• Added LLM image detection, that works remotely through Passio's backend.

Future<List<PassioAdvisorFoodInfo>> recognizeImageRemote(Uint8List bytes)

• Added a function to retrieve a PassioFoodItem for a v2 PassioID

Future<PassioFoodItem?> fetchFoodItemLegacy(PassioID passioID)

3.0.3

Added APIs

• Added two functions to fetch a list of meal plans and fetch a meal plan for a certain day.

Future<List<PassioMealPlan>> fetchMealPlans()

enum MealTime {
  breakfast,
  lunch,
  dinner,
