Optimized dart code
battery optimized dart package

USAGE #

To add the easy_geofencing to your flutter application read the install instructions. Below are some Android and iOS specifics that are required for the easy_geofencing to work correctly.
FOR ANDROID #
AndroidX
The easy_geofencing plugin requires the AndroidX version of the Android Support Libraries. This means you need to make sure your Android project supports AndroidX. Detailed instructions can be found here.
The TL;DR version is:

Add the following to your "gradle.properties" file:

android.useAndroidX=true
android.enableJetifier=true
copied to clipboard

Make sure you set the compileSdkVersion in your "android/app/build.gradle" file to 30:

android {
compileSdkVersion 30

...
}
copied to clipboard

Make sure you replace all the android. dependencies to their AndroidX counterparts (a full list can be found here: https://developer.android.com/jetpack/androidx/migrate).

Permissions
On Android you'll need to add either the ACCESS_COARSE_LOCATION or the ACCESS_FINE_LOCATION permission to your Android Manifest. To do so open the AndroidManifest.xml file (located under android/app/src/main) and add one of the following two lines as direct children of the <manifest> tag (when you configure both permissions the ACCESS_FINE_LOCATION will be used):
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
copied to clipboard
Starting from Android 10 you need to add the ACCESS_BACKGROUND_LOCATION permission (next to the ACCESS_COARSE_LOCATION or the ACCESS_FINE_LOCATION permission) if you want to continue receiving updates even when your App is running in the background (note that the easy_geofencing plugin doesn't support receiving an processing geofence status updates while running in the background):
<uses-permission android:name="android.permission.ACCESS_BACKGROUND_LOCATION" />

FOR IOS #
On iOS you'll need to add the following entries to your Info.plist file (located under ios/Runner) in order to access the device's location. Simply open your Info.plist file and add the following:
<key>NSLocationWhenInUseUsageDescription</key>
<string>This app needs access to location when open.</string>
<key>NSLocationAlwaysUsageDescription</key>
<string>This app needs access to location when in the background.</string>
copied to clipboard
If you would like to receive updates when your App is in the background, you'll also need to add the Background Modes capability to your XCode project (Project > Signing and Capabilities > "+ Capability" button) and select Location Updates. Be careful with this, you will need to explain in detail to Apple why your App needs this when submitting your App to the AppStore. If Apple isn't satisfied with the explanation your App will be rejected.

pointedLatitude: the latitude of the geofence area center
pointedLongitude: the longitude of the geofence area center
radiusInMeter: the radius of the geofence area in meters
eventPeriodInSeconds: geofence status stream period in seconds

import 'package:easy_geofencing/easy_geofencing.dart';

EasyGeofencing.startGeofenceService(
pointedLatitude: "34.2165157",
pointedLongitude: "71.9437819",
radiusMeter: "250.0",
eventPeriodInSeconds: 5
);

GET GEOFENCE STATUS STREAMS #
To get the stream geofence Status updates on location changes, you need to subscribe getGeofenceStream to listen geofence status streams on current location updates.
import 'package:easy_geofencing/easy_geofencing.dart';

StreamSubscription<GeofenceStatus> geofenceStatusStream = EasyGeofencing.getGeofenceStream().listen(
(GeofenceStatus status) {
print(status.toString());
});

Stop Geofence Service #
To stop geofence service you need to specify this:
import 'package:easy_geofencing/easy_geofencing.dart';

EasyGeofencing.stopGeofenceService();
copied to clipboard
Also, stop GeofenceStatus stream subscription listener which is geofenceStatusStream in our case
