Nominatim Location Picker is a package that appears as a FREE alternative (WITH NO API KEYS OR EVEN ACCESSTOKEN, NONE OF THEM ARE NECESSARY) with support for Geocoding with a beautiful and coherent interface using the OpenStreetMap Nominatim.

In the current version, support for Mapbox has also been added, with an interface in line with Nominatim so you can choose which one to use or vary between the two of them.

OpenStreetMap Nominatim #

Nominatim (from the Latin, 'by name') is a tool to search OpenStreetMap data

by name and address (geocoding) and to generate synthetic addresses of

OSM points (reverse geocoding). An instance with up-to-date data can be found

at https://nominatim.openstreetmap.org. Nominatim is also used as one of the

sources for the Search box on the OpenStreetMap home page.

Nominatim's Documentation #

The documentation of the latest development version is in the

docs/ subdirectory. A HTML version can be found at

https://nominatim.org/release-docs/develop/ .

Nominatim's Limitations #

  • No heavy uses (an absolute maximum of 1 request per second).

  • Provide a valid HTTP Referer or User-Agent identifying the application (stock User-Agents as set by http libraries will not do).

  • Clearly display attribution as suitable for your medium.

  • Data is provided under the ODbL license which requires to share alike (although small extractions are likely to be covered by fair usage / fair dealing).

MapBox #

Mapbox is a large provider of custom online maps for websites and applications. Since 2010, it has rapidly expanded the niche of custom maps, as a response to the limited choice offered by map providers such as Google Maps.

MapBox's Documentation #

Mapbox APIs are divided into four distinct services: Maps, Navigation, Search, and Accounts. Each of these services has its own overview page in this documentation. These overview pages are divided into the individual APIs that make up the service. The documentation for each API is structured by endpoints. An endpoint is a specific method within an API that performs one action and is located at a specific URL

https://docs.mapbox.com/api/

Usage #

To use this plugin, add nominatim_location_picker as a dependency in your pubspec.yaml file.


dependencies:

nominatim_location_picker: any # or the latest version on Pub

Import the Nominatim Location Picker in your .dart file...


import  'package:nominatim_location_picker/nominatim_location_picker.dart';

Android Permissions #

The following permissions are recommended.

android.permission.ACCESS_FINE_LOCATION Allows the API to determine as precise a location as possible from the available location providers, including the Global Positioning System (GPS) as well as WiFi and mobile cell data.

android.permission.ACCESS_COARSE_LOCATION Allows the API to use WiFi or mobile cell data (or both) to determine the device's location. The API returns the location with an accuracy approximately equivalent to a city block.


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

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

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