withings_health 0.0.1

A Flutter Package to Read Withings Health Data.

Withings Health Plugin

This plugin supports:

• getting logged in to access health data using the WithingsLogin method.
• reading Activity data using the getWithingsActivityData method.
• reading Sleep data using the getWithingsSleepData method.

Setup

Step 1: Register an Application on developer.withings.com Note: Redirect Url is important as it would be used to navigate back to app after successful login. Example: "yourappname://withings/auth"

Step 2: get clientId and secretKey

Below is a simplified flow of how to use the plugin.

   static const String withingClientID =
      'YOUR_CLIENT_ID';

  // Withings Client Secret
  static const String withingClientSecret =
      'YOUR_SECRET_KEY';

  /// Auth Redirect Uri, 
    //Example testapp://withings/auth
  static const String withingRedirectUri = 'REDIRECT_URI_PROVIDED_AT_TIME_OF_REGISTRATION';

  /// Callback scheme
  static const String withingCallbackScheme = 'CALLBACK_SCHEME_PROVIDED_IN_MANIFEST'; 
  
  //create healthFactory to use methods
  WithingsHealth healthFactory = WithingsHealth();
  
  //To Access activity and sleep Data
  late WithingsDataModel _withingActivityData;
  late WithingsSleepData _withingSleepData;

  //startdate and enddate formatted in
    var formatter = new DateFormat('yyyy-MM-dd');

  setActivityData(WithingsDataModel _activityData) {
    _activityData.body!.activities!.forEach((element) {
      calories = calories + element.calories!.toDouble();

      // Distance in Meters
      distance = distance + element.distance!.toDouble();

      //Distance in Miles if needed
      //distance = distance / 1000 * 0.62137;
      totalCalories = totalCalories + element.totalcalories!.toInt();

      stepCount = stepCount + element.steps!.toInt();
      floors = floors + element.elevation!.toInt();
      duration = duration + element.active!.toInt();
    });
    setState(() {
      calories;
      distance;
      totalCalories;
      stepCount;
      floors;
      duration;
    });
  }

    // Method to set Activity Data state
    setSleepData(WithingsSleepData _sleepData) {
    _sleepData.body!.series!.forEach((element) {
      sleep = sleep + element.data!.asleepduration!.toInt();
      goalSleep = goalSleep + element.data!.durationtosleep!.toInt();
      setState(() {
        sleep;
        goalSleep;
      });
    });
    }
