Setup #
To add the flutter_location_search 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 flutter_location_search 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
copied to clipboard
Make sure you set the compileSdkVersion in your "android/app/build.gradle" file:
android {
compileSdkVersion 33
...
}
copied to clipboard
Make sure you set the minSdkVersion in your "android/app/build.gradle" file:
android {
minSdkVersion 23
...
}
copied to clipboard
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 flutter_location_search plugin):
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
copied to clipboard
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>
copied to clipboard
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's precise location.</string>
</dict>
copied to clipboard
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>
copied to clipboard
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/>

Installing #
Add the following to your pubspec.yaml file:
dependencies:
flutter_location_search: ^1.1.4
copied to clipboard
Getting Started #
Import the following package in your dart file
import 'package:flutter_location_search/flutter_location_search.dart';
copied to clipboard
To use, call the LocationSearch.show() function
```
LocationData? locationData = await LocationSearch.show(
context: context,
mode: Mode.fullscreen
);
```
copied to clipboard
LocationSearch has the following parameters:
onError : (callback) is triggered when an error occurs while fetching location
language : (String) set the language of the address text (default = 'en')
countryCodes : (List) of countries to Limit search results to
loadingWidget : (Widget) show custom widget until the map finish initialization
searchBarBackgroundColor : (Color) change the background color of the search bar
searchBarTextColor : (Color) change the color of the search bar text
searchBarHintText : (String) change the hint text of the search bar
searchBarHintColor : (Color) change the color of the search bar hint text
lightAdress : (bool) if true, displayed and returned adresses will be lighter
iconColor : (Color) change the color of the search bar text
currentPositionButtonText : (String) change the text of the button selecting current position
mode : mode of display (fullscreen or overlay)
historyMaxLength : (int) set the capacity or maximum length of history
Usage #
Location proposals will be displayed when typing in the search bar.
When a location proposal is selected, a LocationData object is returned.
LocationData has three properties.
latitude
longitude
address //String address
addressData //Map<String, dynamic> contains address details
The package also comes with a history of latest searched places. The amount of places to historicize is set by historyMaxLength parameter.
Example #
Here is a snippet od code showing a Button that on tap, shows a widget to search a location;
once a location is selected, the location address is set as the button text.
TextButton(
child: Text(_locationText),
onPressed: () async {
LocationData? locationData = await LocationSearch.show(
context: context,
lightAdress: true,
mode: Mode.fullscreen
);
setState(() {
_locationText = locationData!.address;
});
},
)

Dependencies version solving issues #
You may encounter a dependency version failure because this package uses the 0.18.0 version of intl and some frequently used packages such as firebase_auth use its 0.17.0 version.
To solve this issue, you can add the following to your pubspec.yaml file :
dependency_overrides:
intl: ^0.18.0
