This repository contains a React Native plugin that provides a Google Navigation component for building native Android and iOS apps using React.
Note
This package is in Beta until it reaches version 1.0. According to semantic versioning, breaking changes may be introduced before 1.0.

- A React Native project
- A Google Cloud project
- If you are a Mobility Services developer, you must contact Sales as described in Mobility services documentation.
- If you are not a Mobility Services developer, refer to Setup Google Cloud Project for instructions.
- An API key from the project above
- The API key must be configured for both Android and iOS. Refer to Android Using Api Keys and iOS Using Api Keys respectively for instructions.
- If targeting Android, Google Play Services installed and enabled
- Attributions and licensing text added to your app
Important
Apply API restrictions to the API key to limit usage to "Navigation SDK, "Maps SDK for Android", and "Maps SDK for iOS" for enhanced security and cost management. This helps guard against unauthorized use of your API key.
This package is listed on NPM as @googlemaps/react-native-navigation-sdk. Install it with:
npm i @googlemaps/react-native-navigation-sdkIn your TSX or JSX file, import the components you need:
import { NavigationView } from '@googlemaps/react-native-navigation-sdk';- Set the
minSdkVersioninandroid/app/build.gradle:
android {
defaultConfig {
minSdkVersion 23
}
}To securely store your API key, it is recommended to use the Google Maps Secrets Gradle Plugin. This plugin helps manage API keys without exposing them in your app's source code.
See example configuration for secrets plugin at example applications build.gradle file.
To set up, specify your API key in the application delegate ios/Runner/AppDelegate.m:
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[GMSServices provideAPIKey:@"API_KEY"];
[GMSServices setMetalRendererEnabled:YES];
return [super application:application didFinishLaunchingWithOptions:launchOptions];
}
You can now add a NavigationView component to your application..
The view can be controlled with the ViewController (Navigation and MapView) that are retrieved from the onMapViewControllerCreated and onNavigationViewControllerCreated (respectively).
The NavigationView compoonent should be used within a View with a bounded size. Using it
in an unbounded widget will cause the application to behave unexpectedly.
// Permissions must have been granted by this point.
<NavigationView
androidStylingOptions={{
primaryDayModeThemeColor: '#34eba8',
headerDistanceValueTextColor: '#76b5c5',
headerInstructionsFirstRowTextSize: '20f',
}}
iOSStylingOptions={{
navigationHeaderPrimaryBackgroundColor: '#34eba8',
navigationHeaderDistanceValueTextColor: '#76b5c5',
}}
navigationViewCallbacks={navigationViewCallbacks}
mapViewCallbacks={mapViewCallbacks}
onMapViewControllerCreated={setMapViewController}
onNavigationViewControllerCreated={setNavigationViewController}
termsAndConditionsDialogOptions={termsAndConditionsDialogOptions}
/>You can also add a bare MapView that works as a normal map view without navigation functionality. MapView only need a MapViewController to be controlled.
<MapView
mapViewCallbacks={mapViewCallbacks}
onMapViewControllerCreated={setMapViewController}
/>See the example directory for a complete navigation sample app.
The Google Navigation SDK React Native library offers functionalities that necessitate specific permissions from the mobile operating system. These include, but are not limited to, location services, background execution, and receiving background location updates.
Note
The management of these permissions falls outside the scope of the Navigation SDKs for Android and iOS. As a developer integrating these SDKs into your applications, you are responsible for requesting and obtaining the necessary permissions from the users of your app.
You can see example of handling permissions in the app.tsx file of the sample application:
import {request, PERMISSIONS, RESULTS} from 'react-native-permissions';
// ...
// Request permission for accessing the device's location.
const requestPermissions = async () => {
const result = await request(
Platform.OS === "android" ?
PERMISSIONS.ANDROID.ACCESS_COARSE_LOCATION :
PERMISSIONS.IOS.LOCATION_ALWAYS,
);
if (result === RESULTS.GRANTED) {
setArePermissionsApproved(true);
} else {
Snackbar.show({
text: 'Permissions are needed to proceed with the app. Please re-open and accept.',
duration: Snackbar.LENGTH_SHORT,
});
}
};By default, NavigationView uses all the available space provided to it. To adjust the size of the NavigationView, use the style prop.
<NavigationView
style={{width: 200, height: 50%}}
...
/>This plugin is compatible with both Android Auto and Apple CarPlay infotainment systems. For more details, please refer to the respective platform documentation:
This package uses the Google Maps Navigation SDK for Android and iOS, which includes a dependency on the Google Maps SDK. If your project includes other React Native libraries with Google Maps SDK dependencies, you may encounter build errors due to version conflicts. To avoid this, it's recommended to avoid using multiple packages with Google Maps dependencies.
Note
This package provides a MapView component, which can be used as a classic Google Maps view without navigation. See Add a map view for details.
