---

An easy way to open a location in a map app of the user's choice, based on the apps they have installed on their device.

Currently supported apps:

• Apple Maps – apple-maps
• Google Maps – google-maps
• Citymapper – citymapper
• Uber – uber
• Lyft – lyft
• The Transit App – transit
• Waze – waze
• Yandex.Navi – yandex
• Moovit – moovit
• Yandex Maps – yandex-maps

Installation

1. Install the package

npm i -S react-native-map-link         # or yarn add react-native-map-link

2. Update your Info.plist

To allow your app to detect if any of the directions apps are installed, an extra step is required on iOS. Your app needs to provide the LSApplicationQueriesSchemes key inside ios/Info.plist to specify the URL schemes with which the app can interact.

Just put this in your Info.plist depending on which apps you'd like to support. Omitting these might mean that the library can't detect some of the maps apps installed by the user.

<key>LSApplicationQueriesSchemes</key>
<array>
    <string>comgooglemaps</string>
    <string>citymapper</string>
    <string>uber</string>
    <string>lyft</string>
    <string>transit</string>
    <string>waze</string>
    <string>yandexnavi</string>
    <string>moovit</string>
    <string>yandexmaps</string>
</array>

Usage

Using the showLocation function will shown an action sheet on iOS and an alert on Android, without any custom styling:

import { showLocation } from 'react-native-map-link'

showLocation({
    latitude: 38.8976763,
    longitude: -77.0387185,
    sourceLatitude: -8.0870631,  // optionally specify starting location for directions
    sourceLongitude: -34.8941619,  // not optional if sourceLatitude is specified
    title: 'The White House',  // optional
    googleForceLatLon: false,  // optionally force GoogleMaps to use the latlon for the query instead of the title
    googlePlaceId: 'ChIJGVtI4by3t4kRr51d_Qm_x58',  // optionally specify the google-place-id
    alwaysIncludeGoogle: true, // optional, true will always add Google Maps to iOS and open in Safari, even if app is not installed (default: false)
    dialogTitle: 'This is the dialog Title', // optional (default: 'Open in Maps')
    dialogMessage: 'This is the amazing dialog Message', // optional (default: 'What app would you like to use?')
    cancelText: 'This is the cancel button text', // optional (default: 'Cancel')
    appsWhiteList: ['google-maps'] // optionally you can set which apps to show (default: will show all supported apps installed on device)
    // app: 'uber'  // optionally specify specific app to use
})

Notes:

• The sourceLatitude/sourceLongitude options only work if you specify both. Currently supports all apps except Waze.
