USAGE

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

2. Authorize:

   To check whethere GoogleFit is already authorized, simply use a function

       GoogleFit.checkIsAuthorized()
   

   Then you can simply refer to GoogleFit.isAuthorized boolean.

   // 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()

   Response:

    [ { 
     sourceName: 'Android',
     device: 'Android',
     sourceId: 'com.google.android.gms',
     calories: 764.189208984375,
     quantity: 6,
     end: 1539774300992,
     tracked: true,
     activityName: 'still',
     start: 1539727200000 },
   { sourceName: 'Android',
     device: 'Android',
     sourceId: 'com.google.android.gms',
     calories: 10.351096153259277,
     quantity: 138,
     end: 1539774486088,
     tracked: true,
     distance: 88.09545135498047,
     activityName: 'walking',
   }]

   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.
