USAGE

1. import GoogleFit, { Scopes } from 'react-native-google-fit'

2. Authorize:

   To check whethere GoogleFit is already authorized, simply use a function, then you can refer to the static property GoogleFit.isAuthorized

       GoogleFit.checkIsAuthorized().then(() => {
           console.log(GoogleFit.isAuthorized) // Then you can simply refer to `GoogleFit.isAuthorized` boolean.
       })

   or with async/await syntax

       await checkIsAuthorized();
       console.log(GoogleFit.isAuthorized);

   // The list of available scopes inside of src/scopes.js file
   const options = {
     scopes: [
       Scopes.FITNESS_ACTIVITY_READ_WRITE,
       Scopes.FITNESS_BODY_READ_WRITE,
     ],
   }
   GoogleFit.authorize(options)
     .then(authResult => {
       if (authResult.success) {
         dispatch("AUTH_SUCCESS");
       } else {
         dispatch("AUTH_DENIED", authResult.message);
       }
     })
     .catch(() => {
       dispatch("AUTH_ERROR");
     })
      
   // ...
   // Call when authorized
   GoogleFit.startRecording((callback) => {
     // Process data from Google Fit Recording API (no google fit app needed)
   });

   Alternatively you can use event listeners (deprecated)

    GoogleFit.onAuthorize(() => {
      dispatch('AUTH SUCCESS')
    })
           
    GoogleFit.onAuthorizeFailure(() => {
      dispatch('AUTH ERROR')
    })

3. Retrieve Steps For Period

   const options = {
     startDate: "2017-01-01T00:00:17.971Z", // required ISO8601Timestamp
     endDate: new Date().toISOString(), // required ISO8601Timestamp
     bucketUnit: "DAY", // optional - default "DAY". Valid values: "NANOSECOND" | "MICROSECOND" | "MILLISECOND" | "SECOND" | "MINUTE" | "HOUR" | "DAY"
     bucketInterval: 1, // optional - default 1. 
   };
      
   GoogleFit.getDailyStepCountSamples(options)
    .then((res) => {
        console.log('Daily steps >>> ', res)
    })
    .catch((err) => {console.warn(err)})
      
   // shortcut functions, 
   // return weekly or daily steps of given date
   // all params are optional, using new Date() without given date, 
   // adjustment is 0 by default, determine the first day of week, 0 == Sunday, 1==Monday, etc.
   GoogleFit.getDailySteps(date).then.catch()
   GoogleFit.getWeeklySteps(date, adjustment).then().catch()

   }]

   Where:

   sourceName = device - 'Android' or 'Android Wear' string
   sourceId - return a value of dataSource.getAppPackageName(). For more info see: https://developers.google.com/fit/android/data-attribution
   start/end - timestamps of activity in format of milliseconds since the Unix Epoch
   tracked - bool flag, is this activity was entered by user or tracked by device. Detected by checking milliseconds of start/end timestamps. Since when user log activity in googleFit they can't set milliseconds
   distance(opt) - A distance in meters.
   activityName - string, equivalent one of these https://developers.google.com/fit/rest/v1/reference/activity-types 
   calories(opt) - double value of burned Calories in kcal.
   quantity(opt) - equivalent of steps number

   Note that optional parametrs are not presented in all activities - only where google fit return some results for this field. Like no distance for still activity.

    This method can update hydration data. An app cannot update data inserted by other apps.

    const hydrationArray = [
      {
        date: Date.parse('2020-02-01'), // required, timestamp
        waterConsumed: 0.225, // required, hydration data for a 0.225 liter drink of water

      if (err) throw "Cant save data to the Google Fit";
    });

14. Delete Hydration

    An app cannot delete data inserted by other apps. startDate and endDate MUST not be the same.

    const options = {
      startDate: '2020-01-01T12:33:18.873Z', // required, timestamp or ISO8601 string
      endDate: new Date().toISOString(), // required, timestamp or ISO8601 string

    GoogleFit.deleteHydration(options, (err, res) => {
      console.log(res);
    });

15. Retrieve Sleep

        GoogleFit.getSleepData(options, (err, res) => {
      console.log(res)
    });

16. Other methods:

    observeSteps(callback); // On Step Changed Event
    
    unsubscribeListeners(); // Put into componentWillUnmount() method to prevent leaks
    
    isAvailable(callback); // Checks is GoogleFit available for current account / installed on device
        
    isEnabled(callback); // Checks is permissions granted
        
    deleteWeight(options, callback); // method to delete weights by options (same as in delete hydration)
     
    openFit(); //method to open google fit app
        
    saveHeight(options, callback);
     
    deleteHeight(options, callback); // method to delete heights by options (same as in delete hydration)
     
    disconnect(); // Closes the connection to Google Play services.
