final geofencingFlutterPlugin = GeofencingFlutterPlugin();
// ...

Check and request permissions

---

Before initializing the SDK it is required that you request for required location permissions.

To check if the location permissions are granted by the user call getPermissionsStatus method.

Future<String?> returnVal = geofencingFlutterPlugin.getPermissionsStatus();

returnVal.then((value){
    debugPrint(value!);
}).catchError((error) {
    debugPrint('An error occurred: ${error.message}');
});

Parameter status will be a string, one of:

• GRANTED_BACKGROUND : User has granted location access even when app is not running in the foreground.
• GRANTED_FOREGROUND : Location access is granted only while user is using the app.
• DENIED: Location access is denied.
• UNKNOWN: Without providing or denying any permission then it will return unknown.

Please note: Plugin will not work as expected if location access is denied.

Requesting location access

To request location access call requestPermissions method of the plugin. This will result in displaying location access permission dialog. This method accepts a boolean parameter background. If this parameter is set to true, then plugin will ask for background location access. Code snippet below asks for background location access.

Future<String?> returnVal = geofencingFlutterPlugin.requestPermissions(background);

returnVal.then((value){
    debugPrint(value!);
}).catchError((error) {
    debugPrint('An error occurred: ${error.message}');
});

Initializing the plugin

---

Plugin can be initialized by simply calling initialize method.

Map<String, String> woosmapSettings = {
    "privateKeyWoosmapAPI": "<<WOOSMAP_KEY>>",
    "trackingProfile": "liveTracking"
};

Future<String?> returnVal = geofencingFlutterPlugin.initialize(woosmapSettings);

returnVal.then((value){
    debugPrint(value!);
}).catchError((error) {
    debugPrint('An error occurred: $error');
});

Both configuration options privateKeyWoosmapAPI and trackingProfile are optional. You can also initialize the plugin by passing null configuration.

Future<String?> returnVal = geofencingFlutterPlugin.initialize();

returnVal.then((value){
    debugPrint(value!);
}).catchError((error) {
    debugPrint('An error occurred: $error');
});

You can also set the Woosmap API key later by calling setWoosmapApiKey method.

Future<String?> returnVal = geofencingFlutterPlugin.setWoosmapApiKey("<<WOOSMAP_KEY>>");

returnVal.then((value){
    debugPrint(value!);
}).catchError((error) {
    debugPrint('An error occurred: ${error.message}');
});

Tracking

---

Once you have initialized the plugin and the user has authorized location permissions, you can start tracking the user’s location.

To start tracking, call:

Future<String?> returnVal = geofencingFlutterPlugin.startTracking('liveTracking');

returnVal.then((value){
    debugPrint(value!);
}).catchError((error) {
    debugPrint('An error occurred: ${error.message}');
});

To stop tracking, call:

Future<String?> returnVal = geofencingFlutterPlugin.stopTracking();

returnVal.then((value){
    debugPrint(value!);
}).catchError((error) {
    debugPrint('An error occurred: ${error.message}');
});

Method startTracking accepts only following tracking profiles

• liveTracking
• passiveTracking
• visitsTracking

Listening to events

---

Location

To listen to location, call watchLocation method. After successful invokation of the method you'll need to call getWatchLocationStream method which will return a stream of Location object. Once you obtain the stream call the listen method of the stream.

Future<String?> returnVal = geofencingFlutterPlugin.watchLocation();

returnVal.then((value){
    //Get the location stream    
    watchLocationStream = geofencingFlutterPlugin.getWatchLocationStream();
    //Listen to the stream
    watchLocationStream.listen((location){
        //Location updates will be recieved here.
        if (location != null) {
            debugPrint(location.locationDescription);
        } else {
            debugPrint("Location is null");
        }
    });
}).catchError((error) {
    debugPrint('An error occurred: $error');
});

To stop getting location updates:

Future<String?> returnVal = geofencingFlutterPlugin.clearLocationWatch();

returnVal.then((value){
    debugPrint(value!);
}).catchError((error) {
    debugPrint('An error occurred: $error');
});

Define the radius value

When you create a Geofence around a POI (previously imported from Woosmap), manually define the radius value:

Future<String?> returnVal = _geofencingFlutterPlugin.setPoiRadius("100");

returnVal.then((value){
    showToast(value!);
}).catchError((error) {
    showToast('An error occurred: ${error.message}');
});

or choose the user_properties subfield that corresponds to radius value of the Geofence:

Future<String?> returnVal = _geofencingFlutterPlugin.setPoiRadius("radiusPOI");

returnVal.then((value){
    showToast(value!);
}).catchError((error) {
    showToast('An error occurred: ${error.message}');
});

Regions

Call watchRegions method to track Regions. Method will invoke a callback with Region object. Method will return a watch id which can be used later to remove the callback.

Future<String?> returnVal = geofencingFlutterPlugin.watchRegion();

returnVal.then((value){
    //Get the region stream    
    watchRegionStream = geofencingFlutterPlugin.getWatchRegionStream();
    //Listen to the stream
    watchRegionStream.listen((region){
        //Region updates will be recieved here.
        if (location != null) {
            debugPrint(region.eventName);
        } else {
            debugPrint("Region is null");
        }
    });
}).catchError((error) {
    debugPrint('An error occurred: $error');
});

To remove watch:

Future<String?> returnVal = geofencingFlutterPlugin.clearRegionWatch();

returnVal.then((value){
    debugPrint(value!);
}).catchError((error) {
    debugPrint('An error occurred: $error');
});

• regionId - Id of the region
• lat - Latitude
• lng - Longitude
• radius - Radius in meters
• type - type of region

Create a custom circle region

GeofenceRegion geofenceRegion = GeofenceRegio(
                                '7F91369E-467C-4CBD-8D41-6509815C4780', 
                                51.50998,

                                180, 
                                RegionType.circle
                            );

Future<String?> returnVal = geofencingFlutterPlugin.addRegion(geofenceRegion);

returnVal.then((value){
    debugPrint(value!);
}).catchError((error) {
    debugPrint('An error occurred: ${error.message}');
});

Create a custom isochrone region

GeofenceRegion geofenceRegion = GeofenceRegio(
                                '7F91369E-467C-4CBD-8D41-6509815C4780', 
                                51.50998, 
                                -0.1337, 
                                180, 
                                RegionType.isochrone
                            );

Future<String?> returnVal = geofencingFlutterPlugin.addRegion(geofenceRegion);

returnVal.then((value){
    debugPrint(value!);
}).catchError((error) {
    debugPrint('An error occurred: ${error.message}');
});

Call removeRegions method to remove a region that you are monitoring. Method will accept the following parameter, and passing a null value will remove all the regions.

Future<String?> returnVal = geofencingFlutterPlugin.removeRegions('7F91369E-467C-4CBD-8D41-6509815C4780');

returnVal.then((value){
    debugPrint(value!);
}).catchError((error) {
    debugPrint('An error occurred: ${error.message}');
});

Or To Delete all Regions

Future<String?> returnVal = geofencingFlutterPlugin.removeRegions();

returnVal.then((value){
    debugPrint(value!);
}).catchError((error) {
    debugPrint('An error occurred: ${error.message}');
});

Local database operations

---

• Get POIs: Call getPois method to get an array of POIs from the local db

// Get single POI
Future<List<Poi>?> returnVal = geofencingFlutterPlugin.getPois(poiId);

returnVal.then((pois){
    if (pois != null){
        debugPrint('POIs: ${pois.length}');
    }
}).catchError((error) {
    debugPrint('An error occurred: ${error.message}');
});

// Get all POIs
Future<List<Poi>?> returnVal = geofencingFlutterPlugin.getPois();

returnVal.then((pois){
    if (pois != null){
        debugPrint('POIs: ${pois.length}');
    }
}).catchError((error) {
    debugPrint('An error occurred: ${error.message}');
});

• Delete POIs: Call removePois method to clear all POIs from the local db.

Future<String?> returnVal = geofencingFlutterPlugin.removePois();

returnVal.then((value){
    debugPrint(value!);
}).catchError((error) {
    debugPrint('An error occurred: ${error.message}');
});

• Get Locations: Call getLocations method to get an array of Locations from the local db.

//Get single location
Future<List<Location>?> returnVal = geofencingFlutterPlugin.getLocations(locationId);

        debugPrint('Regions is null');
    }
}).catchError((error) {
    debugPrint('An error occurred: ${error.message}');
});

Custom tracking profile

---

If preset tracking profiles don’t fit with your use cases, you can build your own profile and uses the startCustomTracking() method. There are two way to host the json file:

• Include json file in the client application (local) for ios.
• For local mode put json file in assets folder in android.
• Host externally in a file folder in your information system (external)

Future<String?> returnVal = geofencingFlutterPlugin.startCustomTracking(ProfileSource.local, 'localProfile.json');

returnVal.then((value){
    debugPrint(value!);
}).catchError((error) {
    debugPrint('An error occurred: ${error.message}');
});

or

Future<String?> returnVal = geofencingFlutterPlugin.startCustomTracking(ProfileSource.external, 'https://raw.githubusercontent.com/lpernelle-wgs/files/master/customProfileLeo.json');

returnVal.then((value){
    debugPrint(value!);
}).catchError((error) {
    debugPrint('An error occurred: ${error.message}');
});

Build a custom tracking profile

Define tracking properties in a Json file that respect the Json Schema in the Tracking properties page.
