## Expected Behavior
<!--- Tell us what should happen -->
Reduction in the number of notifications that the users are receiving on their devices. I believe there should be an option to adjust whether we want to show notification or not. apart from that there is sound with notification which I also needs to addressed, there should an option to turn off and on the sound.

## Actual Behavior
<!--- Tell us what happens instead -->
There are a lot of notifications that are being received on the devices that may bother the users a lot and eventually comes out as a bad experience,

## Steps to Reproduce
<!--- reproduce this issue; include code to reproduce, if relevant -->
1. Basic configuration of plugin.
2. Call this function in initstate of your homescreen/ dashboard screen

Future _initPlatformState() async { SharedPreferences prefs = await _prefs; String orgname = prefs.getString("orgname"); String username = prefs.getString("username");

// Sanity check orgname & username:  if invalid, go back to HomeApp to re-register device.
// if (orgname == null || username == null) {
//   return runApp(HomeApp());
// }

// Fetch a Transistor demo server Authorization token for tracker.transistorsoft.com.
bg.TransistorAuthorizationToken token =
    await bg.TransistorAuthorizationToken.findOrCreate(
        orgname, username, ENV.TRACKER_HOST);

// 1.  Listen to events (See docs for all 12 available events).
bg.BackgroundGeolocation.onLocation(_onLocation, _onLocationError);
bg.BackgroundGeolocation.getCurrentPosition().then((location) async {
  print("savedlocation ");
  var user = await getUser();
  Future.delayed(const Duration(seconds: 35), () {
    HomeRepo()
        .updateLocation(
            token: user.data.token,
            lat: location.coords.latitude,
            lng: location.coords.longitude)
        .then((res) {
      showLocalNoti(message: res.message);
    });
  });
});
bg.BackgroundGeolocation.onMotionChange(_onMotionChange); 
bg.BackgroundGeolocation.onActivityChange(_onActivityChange);
bg.BackgroundGeolocation.onProviderChange(_onProviderChange);
bg.BackgroundGeolocation.onConnectivityChange(_onConnectivityChange);
bg.BackgroundGeolocation.onHttp(_onHttp);
bg.BackgroundGeolocation.onAuthorization(_onAuthorization);

// 2.  Configure the plugin

bg.BackgroundGeolocation.ready(bg.Config(
        notificationPriority: 0,
        reset: true,
        debug: true,
        logLevel: bg.Config.LOG_LEVEL_VERBOSE,
        desiredAccuracy: bg.Config.DESIRED_ACCURACY_HIGH,
        distanceFilter: 95.0,
        // locationUpdateInterval: 50000, android only
        backgroundPermissionRationale: bg.PermissionRationale(
            title:
                "Allow {applicationName} to access this device's location even when the app is closed or not in use.",
            message:
                "This app collects location data to enable recording your trips to work and calculate distance-travelled.",
            positiveAction: 'Change to "{backgroundPermissionOptionLabel}"',
            negativeAction: 'Cancel'),
        url: "${ENV.TRACKER_HOST}/api/locations",
        authorization: bg.Authorization(
            // <-- demo server authenticates with JWT
            strategy: bg.Authorization.STRATEGY_JWT,
            accessToken: token.accessToken,
            refreshToken: token.refreshToken,
            refreshUrl: "${ENV.TRACKER_HOST}/api/refresh_token",
            refreshPayload: {'refresh_token': '{refreshToken}'}),
        stopOnTerminate: false,
        stopOnStationary: false,
        preventSuspend: true,
        heartbeatInterval: 60,
        startOnBoot: true,

        enableHeadless: true))
    .then((bg.State state) {
  print("[ready] ${state.toMap()}");
  setState(() {
    _enabled = state.enabled;
    _isMoving = state.isMoving;
  });
}).catchError((error) {
  print('[ready] ERROR: $error');
});

} }


3. That's it.

## Context
<!--- What were you trying to do? -->
We want to get the location and send to server without getting a lot of notification with sound that you can also check in the attached screenshot.

## Debug logs
<!-- include iOS / Android logs
- ios XCode logs,
- use #getLog #emailLog methods (@see docs)
- Android: $ adb logcat -s TSLocationManager
