Flutter Geocoding Plugin

A Flutter Geocoding plugin which provides easy geocoding and reverse-geocoding features.

Important:

1. This plugin uses the free Geocoding services provided by the iOS and Android platforms. This means that there are restrictions to their use. More information can be found in the Apple documentation for iOS and the Google documentation for Android.

2. The availability of the Google Play Services depends on your country. If your country doesn't support a connection with the Google Play Services, you'll need to try a VPN to establish a connection. For more information about how to work with Google Play Services visit the following link: https://developers.google.com/android/guides/overview

Usage

To use this plugin, add geocoding as a dependency in your pubspec.yaml file. For example:

dependencies:
  geocoding: ^1.0.5

NOTE: This plugin relies on the AndroidX version of the Android Support Libraries. This means you need to make sure your Android project is also upgraded to support AndroidX. Detailed instructions can be found here.

The TL;DR version is:

1. Add the following to your "gradle.properties" file:

android.useAndroidX=true
android.enableJetifier=true

2. Make sure you set the compileSdkVersion in your "android/app/build.gradle" file to 28:

android {
 compileSdkVersion 28

 ...
}

3. Make sure you replace all the android. dependencies to their AndroidX counterparts (a full list can be found here: https://developer.android.com/jetpack/androidx/migrate).

API

To translate an address into latitude and longitude coordinates you can use the placemarkFromAddress method:

import 'package:geocoding/geocoding.dart';

List<Location> locations = await locationFromAddress("Gronausestraat 710, Enschede");

If you want to translate latitude and longitude coordinates into an address you can use the placemarkFromCoordinates method:

import 'package:geocoding/geocoding.dart';

List<Placemark> placemarks = await placemarkFromCoordinates(52.2165157, 6.9437819);

Both the locationFromAddress and placemarkFromCoordinates accept an optional localeIdentifier parameter. This parameter can be used to enforce the results to be formatted (and translated) according to the specified locale. The localeIdentifier should be formatted using the syntax: [languageCode]_[countryCode]. Use the ISO 639-1 or ISO 639-2 standard for the language code and the 2 letter ISO 3166-1 standard for the country code. Some examples are:

Locale identifier	Description
en	All English speakers (will translate all attributes to English)
en_US	English speakers in the United States of America
en_UK	English speakers in the United Kingdom
nl_NL	Dutch speakers in The Netherlands
nl_BE	Dutch speakers in Belgium
