Google Navigation for React Native (Beta)

Description

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.

Requirements

Android iOS
Minimum mobile OS supported SDK 23+ iOS 14.0+

[!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.

Installation

This package is listed on NPM as @googlemaps/react-native-navigation-sdk. Install it with:

npm i @googlemaps/react-native-navigation-sdk

In your TSX or JSX file, import the components you need:

import { NavigationView } from '@googlemaps/react-native-navigation-sdk';

Android

  1. Set the minSdkVersion in android/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.

iOS

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];
}

Usage

Add a navigation view

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}
    />

Add a map view

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.

Requesting and handling permissions

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,
        });
    }
};

Changing the NavigationView size

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%}}
        ...
    />
