Overview

geocoder

Forward and reverse geocoding.

Usage

Import package:geocoder/geocoder.dart, and use the Geocoder.local to access geocoding services provided by the device system.

Example:

import 'package:geocoder/geocoder.dart';

// From a query
final query = "1600 Amphiteatre Parkway, Mountain View";
var addresses = await Geocoder.local.findAddressesFromQuery(query);
var first = addresses.first;
print("${first.featureName} : ${first.coordinates}");

// From coordinates
final coordinates = new Coordinates(1.10, 45.50);
addresses = await Geocoder.local.findAddressesFromCoordinates(coordinates);
first = addresses.first;
print("${first.featureName} : ${first.addressLine}");

You can alternatively use Geocoder.google member for requesting distant data from google services instead of native ones.

You will find links to the API docs on the pub page.

    Migration to AndroidX, add support for language in GoogleGeocoding and fix issue with @UiThread

    Hello, I am migrating the code of my application to AndroidX, so this is a proposal for migration to AndroidX for flutter_geocoder. (https://github.com/aloisdeniel/flutter_geocoder/issues/14) I also removed buildToolsVersion, we don't need it anymore.

    Edit : I also propose the following changes:

    • add support for language in GoogleGeocoding
    • fix issue with "Methods marked with @UiThread must be executed on the main thread" (to support the latest flutter engine version, at least the version 1.6.0 of Flutter). I mean this allows to fix the issue https://github.com/aloisdeniel/flutter_geocoder/issues/18

  • Find Address From Query only gets one address

    Find Address From Query only gets one address

    Hi, Thanks for creating the useful library.

    I am currently trying to implement a method to get possible addresses from a string.

    Everything works as expected but i've noticed that 99% the findAddressesFromQuery function returns one address hit only. I've tried using broad queries to test it such as searching an area with multiple similar results but had no luck reproducing the expected results.

    Ex: UAE Abu Dhabi Batten Embassy (An area with 20+ embassies but I only get one hit)

    Google maps search:

    Screenshot 2021-02-12 at 15 16 20

    function used:

    String query = "UAE Abu Dhabi Batten Embassy";
var addresses = await Geocoder.local.findAddressesFromQuery(query);

    I was hoping someone could give me pointers on how to get the desired results.

    Thanks,

  • Prepare for Uint8List SDK breaking change

    Prepare for Uint8List SDK breaking change

    A recent change to the Dart SDK updated HttpClientResponse to implement Stream<Uint8List> rather than implementing Stream<List<int>>.

    This forwards-compatible change updates calls to Stream.transform(StreamTransformer) to instead call the functionally equivalent StreamTransformer.bind(Stream) API, which puts the stream in a covariant position and thus causes the SDK change to be non-breaking.

    The plugin flutter_geocoder uses a deprecated version of the Android embedding. To avoid unexpected runtime failures, or future build failures, try to see if this plugin supports the Android V2 embedding. Otherwise, consider removing it since a future release of Flutter will remove these deprecated APIs.

    I know you don't have much time at the moment, but would be great if you could update the repo as it gives warnings when building for Android.
