Geofencing

A sample geofencing plugin with background execution support for Flutter. What is geofencing? here

Getting Started

This plugin works on both Android and iOS. Follow the instructions in the following sections for the platforms which are to be targeted.

Android

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"
        ...

iOS

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>
