A federated Flutter plugin for integrating with the native MapsIndoors SDK.

Platform	Android	iOS
Supports	SDK 21+	13.0+

ReadMe

Features

​ Use this plugin to: ​

• Show indoor mapping and navigation.
• Perform real-time wayfinding.
• See location live updates. ​ This plugin is based on the MapsIndoors V4 SDK for Android and iOS. At the moment only Google Maps is supported.

Getting Started

​ Add MapsIndoors version 1.0.0 to your pubspec.yaml. ​

mapsindoors: ^1.0.0

Android

​

Android Gooogle Maps Setup

​ To get the underlying Google Map to function, you need to perform the following steps: ​

1. Navigate to android/app/src/main/res/value.
2. Create a file in this folder called google_maps_api_key.xml.
3. Copy and paste the below code snippet and replace YOUR_KEY_HERE with your Google Maps API key.

​

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="google_maps_key">YOUR_KEY_HERE</string>
</resources>

​

MapsIndoors Gradle Setup

​ The plugin Gradle project has trouble resolving the MapsIndoors dependency, so to ensure that it is resolved correctly, do the following: ​

1. Navigate to the app's project level build.gradle.
2. add maven { url 'https://maven.mapsindoors.com/' } to allprojects/repositories after mavenCentral() ​

allprojects {
    repositories {
        google()
        mavenCentral()
        maven { url 'https://maven.mapsindoors.com/' }
    }
}

​

iOS

iOS Gooogle Maps Setup

​ To get the underlying Google Map to function, you need to perform the following steps:

Providing API key

Swift

1. Navigate to iOS/Runner/AppDelegate.swift.
2. Import GoogleMaps on the class
3. Add this code as the first line inside the application function: GMSServices.provideAPIKey("YOUR GOOGLE MAPS API KEY HERE")

Objective-C

1. Navigate to iOS/Runner/AppDelegate.h.
2. Import #import "GoogleMaps/GoogleMaps.h" on the class.
3. Add this code as the first line inside the application function: [GMSServices provideAPIKey:@"YOUR GOOGLE MAPS API KEY HERE"];

Adding MapsIndoors script specific to Google Maps, to Podfile

After this you should navigate into the iOS folder of your flutter project and add this script to the applications Podfile: MapsIndoors podfile Post install

Usage

​ This section has examples of code for the following tasks: ​

• Showing your Map
• Showing a Route
• Searching Locations
• Changing the look with DisplayRules

​

Showing your Map

​ This snippet shows how to set up MapsIndoors in a Flutter application. First, the MapsIndoorsWidget is added to the application's build tree. ​ Optionally we can add a MPFloorSelector to the map. Here we use MPDefaultFloorSelector as it is provided with the MapsIndoors package. The selector must be added both to the build tree as well as to MapControl in order to function correctly. ​ Once initState() has been called, MapsIndoors begins initialization, and once that is done successfully, MapControl begins initialization. ​ Once MapControl is initialized we can invoke the goTo method to move the camera to the default venue. ​

class MapWidgetState extends State<MapWidget> {
    // Let's build a floor selector widget here, we need to add this to MapControl later.
    final _floorSelectorWidget = MPDefaultFloorSelector();
    // MapControl will be initialized after MapsIndoors.
    late final MapControl _mapControl;
​
    @override
    Widget build(BuildContext context) {
        return Scaffold(
            body: Container(
                // Add the MapsIndoors Widget to your Widget, it will automatically fill the container it is placed in.
                child: MapsIndoorsWidget(
                    // build with the default floor selector, this is optional.
                    floorSelector: _floorSelectorWidget,
                ),
            ),
        );
    }
​
    @override
    void initState() {
        super.initState();
        // Start initializing mapsindoors, replace the string with your own api key.
        _mapsIndoorsReadyListener(MapsIndoors.load("your_mapsindoors_api_key"));
    }
​
    void _mapsIndoorsReadyListener(Future<MPError?> error) async {
        if ((await error) == null) {
        // if no errors occured during MapsIndoors load, then we can initialize MapControl
        // we use setFloorSelector to allow MapControl to fill out the floor selector widget with floor information
            MapControl.create(MPMapConfig().setFloorSelector(_floorSelectorWidget)).then((mc) async {
                _mapControl = mc;
                // After initialization, lets show some indoor maps, here we move the camera to the default venue.
                _mapControl.goTo(await MapsIndoors.getDefaultVenue());
            }).catchError((err) {
                print("Creating mapcontrol faced an issue: $err");
            });
        } else {
            print("MapsIndoors faced an error: $error");
        }
    }
}

​

Showing a Route

​ This code snippet initializes the MPDirectionsService and MPDirectionsRenderer classes, and uses _mapControl which has been initialized elsewhere. ​ The showRouteToLocation function is used to query a route from the user's current position to a specified location using directionsService.getRoute(). ​ If successful, the route is displayed on the map using directionsRenderer.setRoute(route). ​

// We assume MapControl has already been initialized
late final _mapControl;
​
// The user is positioned somewhere in the world
var _userLocation = MPPoint.withCoordinates(longitude: -98.44, latitude: 35.16);
/// Query a route to a location from the user's position
void showRouteToLocation(MPLocation location) async {
    // initialize services
    final directionsService = MPDirectionsService();
    final directionsRenderer = MPDirectionsRenderer();
​
    // get the route from userlocation to the location
    directionsService.getRoute(origin: _userPosition, destination: location.point).then((route) {
        // When we have the route, we can show it on the map
        directionsRenderer.setRoute(route);
    }).catchError((err) => print("An error occured: $err")); // otherwise handle the error
}

​

Searching Locations

​ This code snippet shows a function called searchForParking that takes a single argument of type MPPoint. The function uses MapsIndoors to search for locations matching the query string "parking" near the point specified. ​ It mathces in the locations' descriptions, names, and external IDs to the query string. Once the search is complete, it is possible to update/get information from the locations (not specified in the code snippet). ​

/// This method searches for locations 
void searchForParking(MPPoint point) {
    final mpq = MPQueryBuilder();
    // Set the search string
    mpq.setQuery("parking");
    // Set the point where we would like to search around
    mpq.setNear(point);
    // We are searcing in the locations description, name and external id.
    mpq.setQueryProperties([MPLocationPropertyNames.description.name, MPLocationPropertyNames.name.name, MPLocationPropertyNames.externalId.name]);
    // Apply the query on MapsIndoors.
    MapsIndoors.getLocationsByQuery(query: mpq.build()).then((locations) {
        print("number of paring near the point: ${locations?.length}");
        // do something with the locations
    });
}

​

Changing the look with DisplayRules

​ This code snippet shows three ways to manipulate display rules in the MapsIndoors SDK. ​ The hideLocationsByDefault() method hides all markers that are not explicitly visible by setting the main display rule to not visible. ​ The showLocationsByDefault() method ensures all markers are shown by setting the main display rule to visible. ​ The changeTypePolygonColor(String type, String color) method changes the fill color for all polygons belonging to a specific type. It gets the display rule for the specified type using getDisplayRuleByName, and sets the fill color using setPolygonFillColor. ​ These methods can all be used to customize the display of markers and polygons on the map. ​

/// This method changes the main display rule to hide all markers,
/// This will cause all locations that are not explicitly visible to be hidden.
void hideLocationsByDefault() async {
    final MPDisplayRule? main = await MapsIndoors.getMainDisplayRule();
    main?.setVisible(false);
}
​
/// This method changes the main display rule to show all markers,
/// This will cause all locations that are not explicitly visible to be shown.
void showLocationsByDefault() async {
    final MPDisplayRule? main = await MapsIndoors.getMainDisplayRule();
    main?.setVisible(true);
}
​
/// This method changes the fill color for all polygons belonging to a specific [type]
/// the [color] MUST be a valid hex color string.
void changeTypePolygonColor(String type, String color) async {
    final MPDisplayRule? rule = await MapsIndoors.getDisplayRuleByName(type);
    rule?.setPolygonFillColor(color);
}
