# flutter_background_geolocation
[](https://www.transistorsoft.com)
-------------------------------------------------------------------------------
The *most* sophisticated background **location-tracking & geofencing** module with battery-conscious motion-detection intelligence for **iOS** and **Android**.
The plugin's [Philosophy of Operation](https://github.com/transistorsoft/flutter_background_geolocation/wiki/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](https://github.com/transistorsoft/cordova-background-geolocation-lt), [React Native](https://github.com/transistorsoft/react-native-background-geolocation), [NativeScript](https://github.com/transistorsoft/nativescript-background-geolocation-lt) and [pure native](https://github.com/transistorsoft/background-geolocation-lt) apps.
----------------------------------------------------------------------------
The **[Android module](https://www.transistorsoft.com/shop/products/flutter-background-geolocation)** requires [purchasing a license](https://www.transistorsoft.com/shop/products/flutter-background-geolocation). However, it *will* work for **DEBUG** builds. It will **not** work with **RELEASE** builds [without purchasing a license](https://www.transistorsoft.com/shop/products/flutter-background-geolocation).
(2018) This plugin is supported **full-time** and field-tested **daily** since 2013.

## 🔷 Installing the Plugin
📂 **`pubspec.yaml`**:
**Note:** See [Versions](https://pub.dartlang.org/packages/flutter_background_geolocation/#-versions-tab-) for latest available version.
```yaml
dependencies:
flutter_background_geolocation: '^4.12.0'
```
### Or latest from Git:
```yaml
dependencies:
flutter_background_geolocation:
git:
url: https://github.com/transistorsoft/flutter_background_geolocation.git
```
## 🔷 Setup Guides
- [iOS](https://github.com/transistorsoft/flutter_background_geolocation/blob/master/help/INSTALL-IOS.md)
- [Android](https://github.com/transistorsoft/flutter_background_geolocation/blob/master/help/INSTALL-ANDROID.md)
## 🔷 Using the plugin ##
```dart
import 'package:flutter_background_geolocation/flutter_background_geolocation.dart' as bg;
```
⚠️ Note `as bg` in the `import`. This is important to namespace the plugin's classes, which often use common class-names such as `Location`, `Config`, `State`. You will access every `flutter_background_geolocation` class with the prefix `bg` (ie: "**b**ackground **g**eolocation").
## 🔷 Example
[Full Example](https://gist.github.com/christocracy/a0464846de8a9c27c7e9de5616082878)
There are three main steps to using `BackgroundGeolocation`:
1. Wire up event-listeners.
2. Configure the plugin with `#ready`.
3. `#start` the plugin.
```dart
import 'package:flutter_background_geolocation/flutter_background_geolocation.dart' as bg;
class _MyHomePageState extends State {
@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`](./example) folder.

## 🔷 [Simple Testing Server](https://github.com/transistorsoft/background-geolocation-console)
A simple Node-based [web-application](https://github.com/transistorsoft/background-geolocation-console) 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**.
