A Flutter plugin for integrating Google Maps in iOS and Android applications.
Google Maps for Flutter #
A Flutter plugin that provides a Google Maps widget.
Android | iOS | Web | |
---|---|---|---|
Support | SDK 20+ | iOS 14+ | Same as Flutter's |
Getting Started #
-
Get an API key at https://cloud.google.com/maps-platform/.
-
Enable Google Map SDK for each platform.
- Go to Google Developers Console.
- Choose the project that you want to enable Google Maps on.
- Select the navigation menu and then select "Google Maps".
- Select "APIs" under the Google Maps menu.
- To enable Google Maps for Android, select "Maps SDK for Android" in the "Additional APIs" section, then select "ENABLE".
- To enable Google Maps for iOS, select "Maps SDK for iOS" in the "Additional APIs" section, then select "ENABLE".
- To enable Google Maps for Web, enable the "Maps JavaScript API".
- Make sure the APIs you enabled are under the "Enabled APIs" section.
For more details, see Getting started with Google Maps Platform.
Android #
- Set the
minSdkVersion
inandroid/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"/>
Display Mode
The Android implementation supports multiple platform view display modes. For details, see the Android README.
Cloud-based map styling
Cloud-based map styling works on Android only if AndroidMapRenderer.latest
map renderer has been initialized.
For details, see the Android README.
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 #
You'll need to modify the web/index.html
file of your Flutter Web application
to include the Google Maps JS SDK.
Check the google_maps_flutter_web
README
for the latest information on how to prepare your App to use Google Maps on the
web.
All #
You can now add a GoogleMap
widget to your widget tree.
The map view can be controlled with the GoogleMapController
that is passed to
the GoogleMap
's onMapCreated
callback.
The GoogleMap
widget should be used within a widget with a bounded size. Using it
in an unbounded widget will cause the application to throw a Flutter exception.
Sample Usage #
class MapSample extends StatefulWidget {
const MapSample({super.key});
@override
State<MapSample> createState() => MapSampleState();
}
class MapSampleState extends State<MapSample> {
final Completer<GoogleMapController> _controller =
Completer<GoogleMapController>();
static const CameraPosition _kGooglePlex = CameraPosition(
target: LatLng(37.42796133580664, -122.085749655962),
zoom: 14.4746,
);
static const CameraPosition _kLake = CameraPosition(
bearing: 192.8334901395799,
target: LatLng(37.43296265331129, -122.08832357078792),
tilt: 59.440717697143555,
zoom: 19.151926040649414);
@override
Widget build(BuildContext context) {
return Scaffold(
body: GoogleMap(
mapType: MapType.hybrid,
initialCameraPosition: _kGooglePlex,
onMapCreated: (GoogleMapController controller) {
_controller.complete(controller);
},
),
floatingActionButton: FloatingActionButton.extended(
onPressed: _goToTheLake,
label: const Text('To the lake!'),
icon: const Icon(Icons.directions_boat),
),
);
}
Future<void> _goToTheLake() async {
final GoogleMapController controller = await _controller.future;
await controller.animateCamera(CameraUpdate.newCameraPosition(_kLake));
}
}

directory for a complete sample app.
