flutter_geofence 0.4.0

Flutter Android iOS

Plugin to interact with geofences, and get the user's current/latest location.

flutter_geofence #

A Plugin for all your geofence interactions.

Getting Started #

iOS #

We have a minimum requirement of iOS 9.0.

In your Info.plist you'll need to add following keys:

  • NSLocationWhenInUseUsageDescription
  • NSLocationAlwaysAndWhenInUseUsageDescription

Android #

In your AndroidManifest.xml you should add the following lines:

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

If you want to build for android 10+ you need to add ACCESS_BACKGROUND_LOCATION too.

<uses-permission android:name="android.permission.ACCESS_BACKGROUND_LOCATION" />

You'll need to register for a background service as well.

<receiver android:name="com.intivoto.geofence.GeofenceBroadcastReceiver"
    android:enabled="true" android:exported="true"/>
<service android:name="com.intivoto.geofence.GeofencePlugin"
    android:permission="android.permission.BIND_JOB_SERVICE" android:exported="true"/>

This should be sufficient if your app runs with the new Android embedding (v2, Flutter 1.12), also see: https://flutter.dev/docs/development/packages-and-plugins/plugin-api-migration.

Usage #

There is a small example app that prints to console to give an example of functionality of this plugin. At the current time following commands are supported.

Initialize #

Currently you need to initialize the plugin to let it setup it's system. This might be altered in later versions.

Geofence.initialize();

Requesting permission #

In first versions of the plugin permissions were automatically handled, but as the user of the plugin might want more control over this (or implement it theirselves), this was moved to a separate call.

Geofence.requestPermissions();

getCurrentLocation #

This will give you a Future which will resolve with the current Coordinate of the user. If there is one that's recent enough (< 60 seconds old), it'll return this location.

Example usage:

Geofence.getCurrentLocation().then((coordinate) {
    print("Your latitude is ${coordinate.latitude} and longitude ${coordinate.longitude}");
});

addGeolocation #

This gives you the possibility to add regions to the native geofence manager. Note that even though by adding them they will get triggered, nothing will happen in your app just yet. You also need to start listening to them. You'll get a callback to tell you that your region has been scheduled though.

Geofence.addGeolocation(location, GeolocationEvent.entry).then((onValue) {
    scheduleNotification("Georegion added", "Your geofence has been added!");
}).catchError((error) {
    print("failed with $error");
});

removeGeolocation #

This gives you the possibility to remove regions you earlier added. Use it like:

Geofence.removeGeolocation(location, GeolocationEvent.entry).then((onValue) {
    scheduleNotification("Georegion removed", "Your geofence has been removed!");
}).catchError((error) {
    print("failed with $error");
});

startListening #

Start listening to geoevents as they happen.

Geofence.startListening(GeolocationEvent.entry, (entry) {
    scheduleNotification("Entry of a georegion", "Welcome to: ${entry.id}");
});

startListeningForLocationChanges #

Starts listening for significant location changes on iOS, requests the location every 15 minutes on low power on Android.

Geofence.startListeningForLocationChanges();

stopListeningForLocationChanges #

Stops listening for significant location changes on iOS, stops requesting the location every 15 minutes on low power on Android.

Geofence.stopListeningForLocationChanges();

backgroundLocationUpdated #

This is a stream you can listen to, only triggered by the listening for significant location changes.

Geofence.backgroundLocationUpdated.stream.listen((event) {
    scheduleNotification("You moved significantly", "a significant location change just happened.");
});
