What is geofencing? here
A sample geofencing plugin with background execution support for Flutter.
This plugin works on both Android and iOS. Follow the instructions in the following sections for the platforms which are to be targeted.
Add the following lines to your AndroidManifest.xml
to register the background service for
geofencing:
<receiver android:name="io.flutter.plugins.geofencing.GeofencingBroadcastReceiver"
android:enabled="true" android:exported="true"/>
<service android:name="io.flutter.plugins.geofencing.GeofencingService"
android:permission="android.permission.BIND_JOB_SERVICE" android:exported="true"/>
Also request the correct permissions for geofencing:
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_BACKGROUND_LOCATION" />
Finally, create either Application.kt
or Application.java
in the same directory as MainActivity
.
For Application.kt
, use the following:
class Application : FlutterApplication(), PluginRegistrantCallback {
override fun onCreate() {
super.onCreate();
GeofencingService.setPluginRegistrant(this);
}
override fun registerWith(registry: PluginRegistry) {
GeneratedPluginRegistrant.registerWith(registry);
}
}
For Application.java
, use the following:
public class Application extends FlutterApplication implements PluginRegistrantCallback {
@Override
public void onCreate() {
super.onCreate();
GeofencingService.setPluginRegistrant(this);
}
@Override
public void registerWith(PluginRegistry registry) {
GeneratedPluginRegistrant.registerWith(registry);
}
}
Which must also be referenced in AndroidManifest.xml
:
<application
android:name=".Application"
...
Add the following lines to your Info.plist:
<dict>
<key>NSLocationAlwaysAndWhenInUseUsageDescription</key>
<string>YOUR DESCRIPTION HERE</string>
<key>NSLocationWhenInUseUsageDescription</key>
<string>YOUR DESCRIPTION HERE</string>
...
And request the correct permissions for geofencing:
<dict>
...
<string>Main</string>
<key>UIRequiredDeviceCapabilities</key>
<array>
<string>location-services</string>
<string>gps</string>
<string>armv7</string>
</array>
<key>UIBackgroundModes</key>
<array>
<string>location</string>
</array>
...
</dict>
