Getting Started #

Setup #

To add the location_picker_flutter_map to your Flutter application read the instructions. Below are some Android and iOS specifics that are required for the package to work correctly.

Android

Upgrade pre 1.12 Android projects

Since version 5.0.0 this plugin is implemented using the Flutter 1.12 Android plugin APIs. Unfortunately this means App developers also need to migrate their Apps to support the new Android infrastructure. You can do so by following the Upgrading pre 1.12 Android projects migration guide. Failing to do so might result in unexpected behaviour.

AndroidX

The location_picker_flutter_map plugin requires the AndroidX version of the Android Support Libraries. This means you need to make sure your Android project supports AndroidX. Detailed instructions can be found here.

The TL;DR version is:

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

android.useAndroidX=true
android.enableJetifier=true

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

android {
  compileSdkVersion 33

  ...
}

Make sure you set the minSdkVersion in your "android/app/build.gradle" file:

android {
  minSdkVersion 23

  ...
}

Make sure you replace all the android. dependencies to their AndroidX counterparts (a full list can be found here: Migrating to AndroidX).

Permissions

On Android you'll need to add either the ACCESS_COARSE_LOCATION or the ACCESS_FINE_LOCATION permission to your Android Manifest. To do so open the AndroidManifest.xml file (located under android/app/src/main) and add one of the following two lines as direct children of the <manifest> tag (when you configure both permissions the ACCESS_FINE_LOCATION will be used by the location_picker_flutter_map plugin):

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

NOTE: Specifying the ACCESS_COARSE_LOCATION permission results in location updates with an accuracy approximately equivalent to a city block. It might take a long time (minutes) before you will get your first locations fix as ACCESS_COARSE_LOCATION will only use the network services to calculate the position of the device. More information can be found here.

iOS

On iOS you'll need to add the following entries to your Info.plist file (located under ios/Runner) in order to access the device's location. Simply open your Info.plist file and add the following (make sure you update the description so it is meaningful in the context of your App):

<key>NSLocationWhenInUseUsageDescription</key>
<string>This app needs access to location when open.</string>
<key>NSLocationAlwaysUsageDescription</key>
<string>This app needs access to location when in the background.</string>

If you would like to receive updates when your App is in the background, you'll also need to add the Background Modes capability to your XCode project (Project > Signing and Capabilities > "+ Capability" button) and select Location Updates. Be careful with this, you will need to explain in detail to Apple why your App needs this when submitting your App to the AppStore. If Apple isn't satisfied with the explanation your App will be rejected.

When using the requestTemporaryFullAccuracy({purposeKey: "YourPurposeKey"}) method, a dictionary should be added to the Info.plist file.

<key>NSLocationTemporaryUsageDescriptionDictionary</key>
<dict>
  <key>YourPurposeKey</key>
  <string>The example App requires temporary access to the device&apos;s precise location.</string>
</dict>

The second key (in this example called YourPurposeKey) should match the purposeKey that is passed in the requestTemporaryFullAccuracy() method. It is possible to define multiple keys for different features in your app. More information can be found in Apple's documentation.

NOTE: the first time requesting temporary full accuracy access it might take several seconds for the pop-up to show. This is due to the fact that iOS is determining the exact user location which may take several seconds. Unfortunately this is out of our hands.

macOS

On macOS you'll need to add the following entries to your Info.plist file (located under macOS/Runner) in order to access the device's location. Simply open your Info.plist file and add the following (make sure you update the description so it is meaningful in the context of your App):

<key>NSLocationUsageDescription</key>
<string>This app needs access to location.</string>

You will also have to add the following entry to the DebugProfile.entitlements and Release.entitlements files. This will declare that your App wants to make use of the device's location services and adds it to the list in the "System Preferences" -> "Security & Privacy" -> "Privacy" settings.

<key>com.apple.security.personal-information.location</key>
<true/>

When using the requestTemporaryFullAccuracy({purposeKey: "YourPurposeKey"}) method, a dictionary should be added to the Info.plist file.

<key>NSLocationTemporaryUsageDescriptionDictionary</key>
<dict>
  <key>YourPurposeKey</key>
  <string>The example App requires temporary access to the device&apos;s precise location.</string>
</dict>

NOTE: the first time requesting temporary full accuracy access it might take several seconds for the pop-up to show. This is due to the fact that macOS is determining the exact user location which may take several seconds. Unfortunately this is out of our hands.

Installing #

Add the following to your pubspec.yaml file:

dependencies:
  location_picker_flutter_map: ^3.0.1

Simple Usage #

Import the following package in your dart file

import 'package:location_picker_flutter_map/location_picker_flutter_map.dart';

To use is simple, just call the widget bellow. You need to pass the onPicked method to get the picked position from the map.

FlutterLocationPicker(
        initZoom: 11,
        minZoomLevel: 5,
        maxZoomLevel: 16,
        trackMyPosition: true,
        onPicked: (pickedData) {
        })

Then Usage #

Now if you press Set Current Location button, you will get the pinned location by onPicked method.

Or you can use onChanged method to get the picked data whenever user change marker location on map.

The onPicked and onChanged methods return pickedData.

pickedData has three properties.

latLong
address //String address
addressData //Map<String, dynamic> contains address details

latLong has two more properties.

latitude
longitude

For example

FlutterLocationPicker(
        initPosition: LatLong(23, 89),
        selectLocationButtonStyle: ButtonStyle(
          backgroundColor: MaterialStateProperty.all(Colors.blue),
        ),
        selectedLocationButtonTextstyle: const TextStyle(fontSize: 18),
        selectLocationButtonText: 'Set Current Location',
        selectLocationButtonLeadingIcon: const Icon(Icons.check),
        initZoom: 11,
        minZoomLevel: 5,
        maxZoomLevel: 16,
        trackMyPosition: true,
        onError: (e) => print(e),
        onPicked: (pickedData) {
          print(pickedData.latLong.latitude);
          print(pickedData.latLong.longitude);
          print(pickedData.address);
          print(pickedData.addressData['country']);
        },
        onChanged: (pickedData) {
          print(pickedData.latLong.latitude);
          print(pickedData.latLong.longitude);
          print(pickedData.address);
          print(pickedData.addressData);
        })

You can get latitude, longitude, address and addressData like that.

Custom Map Style #

You can apply themes to your map using Map Tiler

Head to the website and sign up then choose the map tile you want

Get the Maptile Url like this

  https://api.maptiler.com/maps/hybrid/{z}/{x}/{y}.jpg?{apikey}

use it in the urlTemplate parameter.

FlutterLocationPicker(
    urlTemplate:
        'https://api.maptiler.com/maps/hybrid/{z}/{x}/{y}.jpg?key={apikey}',
    )
