# Flutter SDK Changelog

> A changelog documenting version updates and changes of Spike SDK for Flutter platform.

## 4.5.24

* Updated Android SDK to `4.5.22`
* Updated iOS SDK to `4.5.21`
* Added **backfill** on the v3 connection to upload historical health data for a chosen number of days. Call it after you have granted the relevant permissions (HealthKit on iOS; Health Connect and/or Samsung Health Data on Android).
  ```dart theme={null}
  await spikeConnection.backfill(
    statisticTypes: statisticTypes,
    metricTypes: metricTypes,
    activityConfigs: [activityConfig],
    sleepConfigs: [sleepConfig],
  );
  ```
* **iOS (HealthKit):** added `requestPermissionsFromHealthKitAndBackfill` — requests read permissions for the given categories, then starts a backfill. Data for today and yesterday is pushed before the call resolves; older days continue in the background.
  ```dart theme={null}
  await spikeConnection.requestPermissionsFromHealthKitAndBackfill(
    statisticTypes: statisticTypes,
    metricTypes: metricTypes,
    activityConfigs: [activityConfig],
    sleepConfigs: [sleepConfig],
  );
  ```
* **Android (Samsung Health Data):** added `requestPermissionsFromSamsungHealthDataAndBackfill` — enables Samsung Health Data integration, requests permissions for the given categories, then starts a backfill.
* **Android (Health Connect):** added `requestPermissionsFromHealthConnectAndBackfill` — enables Health Connect integration, requests permissions for the given categories, then starts a backfill.
* **iOS:** If after updating you get errors while building iOS app please do following:
  1. `rm -rf ios/Pods/ ios/Podfile.lock` - delete old pods
  2. `cd ios; pod install --repo-update` - install updated pods
  3. Open project in Xcode and do a full clean: `Product -> Clean build folder` or `Shift + Command + K`

## 4.5.14

* Added `RecordConfig` for configuring records queries:
  * `includeSamples` - whether to include samples (raw data points) in the response
* Updated `getRecords` to accept an optional `RecordConfig` parameter:
  ```
  spikeConnection.getRecords(
      ofTypes: metricTypes,
      from: startDate,
      to: endDate,
      filter: StatisticsFilter(excludeManual: true),
      config: RecordConfig(includeSamples: true),
  )
  ```
* Fixed ActivityConfig parsing
* Updated Android SDK to `4.5.12`
* Updated iOS SDK to `4.5.11`
  * IMPORTANT! If after updating you get errors while building iOS app please do following:
    1. `rm -rf ios/Pods/ ios/Podfile.lock` - delete old pods
    2. `cd ios; pod install --repo-update` - install updated pods
    3. Open project in XCode 26 and do a full clean: `Product -> Clean build folder` or `Shift + Command + K`

## 4.4.14

  * Removed: `kmh`, `kmPerMin`
* Improved data communication with API
* Enhanced the `getSleep` endpoint.
  Important:
  * Dates provided are now interpreted as dates only; the time component is ignored when querying the API.
  * The primary night sleep period is associated with the calendar date on which it ends.

## 4.3.184

* Updated Android SDK to `4.3.142`
  * Internal improvements
* Updated iOS SDK to `4.3.161`
  * Better Nutrition Facts Label Recognition response parsing

## 4.3.174

* MetricType: added namespace with metric allowlists for API requests:
  * `MetricType.availableForRecordsRequest` – list of metric types available for records requests
  * `MetricType.availableForActivitiesRequest` – list of metric types available for activities requests
  * `MetricType.availableForSleepRequest` – list of metric types available for sleep requests
  * `MetricType.availableForPersonRequest` – list of metric types available for person requests
* Updated iOS SDK to `4.3.151`:
  * Improved data push to API
  * Fixed workout digest generation for caching
  * Improved client cache configuration

    * User profile data (weight, height, birth date, gender)
    * Blood pressure measurements
    * Skin temperature measurements

  * Large Samsung Health Data pushes are now automatically split into smaller chunks for reliable delivery
  * Large Health Connect pushes are now automatically split into smaller chunks for reliable delivery

## 4.3.154

* Added Nutrition Facts Label Recognition for extracting nutritional information from label photos.
  For more information please visit our [documentation](https://docs.spikeapi.com).
  * `recognizeNutritionFactsLabel({required String imageBase64, NutritionFactsLabelRecognitionConfig? config})` - Analyze a nutrition facts label image and extract nutritional data
* Added methods for manual nutrition record management:
  * `createNutritionRecord(NutritionRecord nutritionRecord)` - Insert a new nutrition record with custom data
  * `replaceNutritionRecord(NutritionRecord nutritionRecord)` - Replace an existing nutrition record completely
* Added `NutritionRecordUtils` for creating and manipulating nutrition records:
  * `NutritionRecordUtils.create({...})` - Create a new nutrition record with specified properties
  * `record.withIngredient(ingredient)` - Add an ingredient to a record
  * `record.withoutIngredient(ingredient)` - Remove an ingredient from a record
  * `record.withServingSize(servingSize, unit)` - Update serving size and unit

  * `ingredient.withoutNutritionalField(nutritionalField)` - Remove a nutritional field
  * `ingredient.withScaledServingSize(newServingSize)` - Scale serving size and nutritional values proportionally
* Nutrition AI methods now return `NutritionRecordAnalysisResult` instead of `NutritionRecord`.
  This separates processing metadata (status, failure reason) from the actual nutrition data.
  The following methods are affected:
  * `analyzeNutrition()` → returns `Future<NutritionRecordAnalysisResult>`
  * `getNutritionRecords()` → returns `Future<List<NutritionRecordAnalysisResult>>`
  * `getNutritionRecord()` → returns `Future<NutritionRecordAnalysisResult?>`
  * `updateNutritionRecordServingSize()` → returns `Future<NutritionRecordAnalysisResult>`
  * `createNutritionRecord()` → returns `Future<NutritionRecordAnalysisResult>`
  * `replaceNutritionRecord()` → returns `Future<NutritionRecordAnalysisResult>`
    The `NutritionRecordAnalysisResult` contains:
  * `recordId` - The record ID
  * `status` - Processing status (pending, processing, completed, failed, updated)
  * `failureReason` - Reason for failure (if status is failed)
  * `uploadedAt` - Upload timestamp
  * `nutritionRecord` - The actual `NutritionRecord` (null if status is not completed/updated)
* Update Android SDK to `4.3.122`
* Update iOS SDK to `4.3.141`
  * IMPORTANT! If after updating you get errors while building iOS app please do following:
    1. `rm -rf ios/Pods/ ios/Podfile.lock` - delete old pods
    2. `cd ios; pod install --repo-update` - install updated pods
    3. Open project in XCode 26 and do a full clean: `Product -> Clean build folder` or `Shift + Command + K`

  * `getNutritionRecords(from, to)` - Retrieve nutrition records for a date range
  * `getNutritionRecord(id)` - Get a specific nutrition record by ID
  * `deleteNutritionRecord(id)` - Delete a nutrition record
  * `updateNutritionRecordServingSize(id, servingSize)` - Update serving size for a nutrition record
