Flutter geolocator plugin Geolocator().placemarkFromAddress() and Geolocator().placemarkFromCoordinates() do not work

Question

I am trying to search an address and then trying to get position of that location by Geolocator and then trying to set camera position to this position but it does not work.

I find out some exceptions for two methods of Geolocator. All others methods of Geolodator work fine for me:

1. Geolocator().placemarkFromAddress() shows:

PlatformException(ERROR_GEOCODING_ADDRESS, Service not Available, null)

2. Geolocator().placemarkFromCoordinates() shows:

PlatformException(ERROR_GEOCODING_COORDINATES, Service not Available, null)

Here Code that I am trying:

try {
  List<Placemark> placemark = await Geolocator().placemarkFromAddress(searchAddress);
  Placemark newPlace = placemark[0];
  controller.animateCamera(CameraUpdate.newCameraPosition(CameraPosition(
     target: LatLng(newPlace.position.latitude,newPlace.position.longitude),
     zoom: 15.0,
  )));
}catch(e){
   print(e);
}

Solution 1

placemarkFromCoordinates has been moved from plugin 'geolocator' to 'geocoding', just add plugin 'geocoding' in pubspec.yaml and user placemarkFromCoordinates

Solution 2

Its now moved to https://pub.dev/packages/geocoding

import 'package:flutter/material.dart';
import 'package:google_maps_flutter/google_maps_flutter.dart';
import 'package:geocoding/geocoding.dart';

class MapScreen02 extends StatefulWidget {
  @override
  _MapScreen02State createState() => _MapScreen02State();
}

class _MapScreen02State extends State<MapScreen02> {
  GoogleMapController mapController;
  String searchAdd;
  // List<Location> locations = await locationFromAddress("Gronausestraat 710, Enschede");
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Stack(
        children: [
          GoogleMap(

            initialCameraPosition:
                CameraPosition(target: LatLng(40.7128, -74.0060), zoom: 10.0),
          ),

                    onPressed: searchnavigate,
                    iconSize: 30,
                  ),
                ),
                onChanged: (val) {
                  setState(() {
                    searchAdd = val;
                  });
                },
              ),
            ),
          ),
        ],
      ),
    );
  }

  searchnavigate() {
    locationFromAddress(searchAdd).then((result) {
      mapController.animateCamera(CameraUpdate.newCameraPosition(CameraPosition(
        target: LatLng(result[0].latitude, result[0].longitude),
        zoom: 10,
      )));
    });
  }

  void onMapCreated(controller) {
    setState(() {
      mapController = controller;
    });
  }
}

Are you connected to the internet on your testing device ?

[Md Mahmudul Islam]

yes. I am running this app in real device and internet connection was available. All others methods of geolocator works fine.

Maybe some problem with your ISP or country you are working from because in my demo project this is just working fine (Austria)
