Suspend location logging

flutter_background_geolocation

The most sophisticated background location-tracking & geofencing module with battery-conscious motion-detection intelligence for iOS and Android.

The plugin's Philosophy of Operation is to use motion-detection APIs (using accelerometer, gyroscope and magnetometer) to detect when the device is moving and stationary.

When the device is detected to be moving, the plugin will automatically start recording a location according to the configured distanceFilter (meters).
When the device is detected be stationary, the plugin will automatically turn off location-services to conserve energy.

Also available for Cordova, React Native, NativeScript and pure native apps.

The Android module requires purchasing a license. However, it will work for DEBUG builds. It will not work with RELEASE builds without purchasing a license.

(2018) This plugin is supported full-time and field-tested daily since 2013.

import 'package:flutter_background_geolocation/flutter_background_geolocation.dart' as bg;

class _MyHomePageState extends State<MyHomePage> {

  @override
  void initState() {
    super.initState();

    ////
    // 1.  Listen to events (See docs for all 12 available events).
    //

    // Fired whenever a location is recorded
    bg.BackgroundGeolocation.onLocation((bg.Location location) {
      print('[location] - $location');
    });

    // Fired whenever the plugin changes motion-state (stationary->moving and vice-versa)
    bg.BackgroundGeolocation.onMotionChange((bg.Location location) {
      print('[motionchange] - $location');
    });

    // Fired whenever the state of location-services changes.  Always fired at boot
    bg.BackgroundGeolocation.onProviderChange((bg.ProviderChangeEvent event) {
      print('[providerchange] - $event');
    });

    ////
    // 2.  Configure the plugin
    //
    bg.BackgroundGeolocation.ready(bg.Config(
        desiredAccuracy: bg.Config.DESIRED_ACCURACY_HIGH,
        distanceFilter: 10.0,
        stopOnTerminate: false,
        startOnBoot: true,
        debug: true,
        logLevel: bg.Config.LOG_LEVEL_VERBOSE
    )).then((bg.State state) {
      if (!state.enabled) {
        ////
        // 3.  Start the plugin.
        //
        bg.BackgroundGeolocation.start();
      }
    });
  }
}

⚠️ Do not execute any API method which will require accessing location-services until the callback to **#ready* executes (eg: #getCurrentPosition, #watchPosition, #start).

🔷 Demo Application

A fully-featured Demo App is available in the repo in the /example folder.

🔷 Simple Testing Server

A simple Node-based web-application with SQLite database is available for field-testing and performance analysis. If you're familiar with Node, you can have this server up-and-running in about one minute.
