map_location_picker:
A simple library to pick a location on a map.
Made by Arvind @rvndsngwn:
- Compatibility with Geolocator
- Use of Google map APIs
- Added support for flutter web
- All new customizations are done in the
MapLocationPickerclass
| Android | iOS | Flutter Web | |
|---|---|---|---|
| Support | SDK 20+ | iOS 9+ | Yes |
Location picker using the official google_maps_flutter.
I made This plugin because google deprecated Place Picker.
| Video | Decoded Address | Places autocomplete |

Setup
Pubspec changes:
dependencies:
map_location_picker: ^1.0.1
You can now add a GoogleMap widget to your widget tree.
import 'package:map_location_picker/map_location_picker.dart';
MapLocationPicker(
apiKey: "YOUR_API_KEY",
onNext: (GeocodingResult? result) {
...
},
);
Getting Started
-
Get an API key at https://cloud.google.com/maps-platform/.
-
And don't forget to enable the following APIs in https://console.cloud.google.com/google/maps-apis/
- Maps SDK for Android
- Maps SDK for iOS
- Places API
- Geocoding API
- Maps JavaScript API
-
And ensure to enable billing for the project.
For more details, see Getting started with Google Maps Platform.
Android
- Set the
minSdkVersioninandroid/app/build.gradle:
android {
defaultConfig {
minSdkVersion 20
}
}
This means that app will only be available for users that run Android SDK 20 or higher.
- Specify your API key in the application manifest
android/app/src/main/AndroidManifest.xml:
<manifest ...
<application ...
<meta-data android:name="com.google.android.geo.API_KEY"
android:value="YOUR KEY HERE"/>
Hybrid Composition
To use Hybrid Composition to render the GoogleMap widget on Android, set AndroidGoogleMapsFlutter.useAndroidViewSurface to true.
if (defaultTargetPlatform == TargetPlatform.android) {
AndroidGoogleMapsFlutter.useAndroidViewSurface = true;
}
iOS
To set up, specify your API key in the application delegate ios/Runner/AppDelegate.m:
#include "AppDelegate.h"
#include "GeneratedPluginRegistrant.h"
#import "GoogleMaps/GoogleMaps.h"
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application
didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
[GMSServices provideAPIKey:@"YOUR KEY HERE"];
[GeneratedPluginRegistrant registerWithRegistry:self];
return [super application:application didFinishLaunchingWithOptions:launchOptions];
}
@end
Or in your swift code, specify your API key in the application delegate ios/Runner/AppDelegate.swift:
import UIKit
import Flutter
import GoogleMaps
@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
override func application(
_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
) -> Bool {
GMSServices.provideAPIKey("YOUR KEY HERE")
GeneratedPluginRegistrant.register(with: self)
return super.application(application, didFinishLaunchingWithOptions: launchOptions)
}
}
Web View
Modify web/index.html
Get an API Key for Google Maps JavaScript API. Get started here.
Modify the <head> tag of your web/index.html to load the Google Maps JavaScript API, like so:
<head>
<!-- // Other stuff -->
<script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY"></script>
</head>
Note
The following permissions are not required to use Google Maps Android API v2, but are recommended.
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.
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.
You must also explicitly declare that your app uses the android.hardware.location.network or android.hardware.location.gps hardware features if your app targets Android 5.0 (API level 21) or higher and uses the ACCESS_COARSE_LOCATION or ACCESS_FINE_LOCATION permission in order to receive location updates from the network or a GPS, respectively.
<uses-feature android:name="android.hardware.location.network" android:required="false" />
<uses-feature android:name="android.hardware.location.gps" android:required="false" />
The following permissions are defined in the package manifest, and are automatically merged into your app's manifest at build time. You don't need to add them explicitly to your manifest:
android.permission.INTERNET Used by the API to download map tiles from Google Maps servers.
android.permission.ACCESS_NETWORK_STATE Allows the API to check the connection status in order to determine whether data can be downloaded.
Restricting Autocomplete Search to Region
The Results returned can be restricted to certain countries by passing an array of country codes into the components parameter of MapLocationPicker. Countries must be two character, ISO 3166-1 Alpha-2 compatible. You can find code information at Wikipedia: List of ISO 3166 country codes or the ISO Online Browsing Platform.
The example below restricts Autocomplete Search to the United Arab Emirates and Nigeria
MapLocationPicker(
apiKey: "YOUR_API_KEY",
onNext: (GeocodingResult? result) {
...
},
);
See the example directory for a complete sample app.
