Android setup
Add the following permissions to your manifest:
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_BACKGROUND_LOCATION" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.FOREGROUND_SERVICE" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>
Afterwards, include the following entries within the application tag, as follows:
<application
...
<!-- configuration of background_locator_2 -->
<receiver android:name="yukams.app.background_locator_2.BootBroadcastReceiver"
android:enabled="true"
android:exported="true">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED"/>
</intent-filter>
</receiver>
<service android:name="yukams.app.background_locator_2.IsolateHolderService"
android:permission="android.permission.FOREGROUND_SERVICE"
android:exported="true"
android:foregroundServiceType = "location"/>
</application>
NOTE In Android 11 and above location permissions cannot be set automatically by the app (via the manifest file). Google writes on this page that:
On Android 11 (API level 30) and higher
...
the system dialog doesn’t include the Allow all the time option. Instead, users must enable background location on a settings page, as shown in figure 7.
Hence, for this plugin (and the example app) to work, you need to go to this settings screen and manually set the permission to "Alow all the time".
iOS setup
Add the following entries to your Info.plist
file
<key>NSLocationAlwaysAndWhenInUseUsageDescription</key>
<string>This app needs access to location when open and in the background.</string>
<key>NSLocationAlwaysUsageDescription</key>
<string>This app needs access to location when in the background.</string>
<key>NSLocationWhenInUseUsageDescription</key>
<string>This app needs access to location when open.</string>
<key>UIBackgroundModes</key>
<array>
<string>location</string>
</array>
Next, overwrite your AppDelegate.swift
with:
import UIKit
import Flutter
import background_locator_2
func registerPlugins(registry: FlutterPluginRegistry) -> () {
if (!registry.hasPlugin("BackgroundLocatorPlugin")) {
GeneratedPluginRegistrant.register(with: registry)
}
}
@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
override func application(
_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
) -> Bool {
GeneratedPluginRegistrant.register(with: self)
BackgroundLocatorPlugin.setPluginRegistrantCallback(registerPlugins)
return super.application(application, didFinishLaunchingWithOptions: launchOptions)
}
}

Usage
// configure the location manager
LocationManager().interval = 1;
LocationManager().distanceFilter = 0;
LocationManager().notificationTitle = 'CARP Location Example';
LocationManager().notificationMsg = 'CARP is tracking your location';
// get the current location
await LocationManager().getCurrentLocation();
// start listen to location updates
StreamSubscription<LocationDto> locationSubscription = LocationManager()
.locationStream
.listen((LocationDto loc) => print(loc));
// cancel listening and stop the location manager
locationSubscription?.cancel();
LocationManager().stop();
