situm_flutter_wayfinding 0.0.16

Situm Wayfinding for Flutter.

@situm/flutter-wayfinding

Situm Wayfinding for Flutter. Integrate native plug&play navigation experience with floorplans, POIs, routes and turn-by-turn directions in no time. With the power of Situm.

Getting Started

There is a comprehensive tutorial on how to set-up a new application using this plugin on the Situm documentation page.

Below you will find the basic steps to install and configure the plugin on your Flutter project.

Set up your Situm credentials

Create a new config.dart file with your Situm credentials. You can use the contents of example/config.dart.example as example.

Follow the Wayfinding guide if you haven't set up a Situm account.

Running the example:

Check the example/README file of this repository to create your first Flutter application using Situm Wayfinding.

Android

The following steps have already been done for you in the example application of this repository, but they are required for a new project:

1. Include the Situm repository in your project level build.gradle:

allprojects {
    repositories {
        ...
        maven { url "https://repo.situm.es/artifactory/libs-release-local" }
    }
}

2. Make sure AppCompat library is in your build.gradle dependencies:

implementation 'androidx.appcompat:appcompat:1.4.1'

3. Make sure your MainActivity extends the provided FlutterAppCompatActivity. This class was duplicated from FlutterFragmentActivity to add support to androidx AppCompatActivity, which is not currently supported by Flutter. The WYF plugin must also be registered manually from your MainActivity:

...
import io.flutter.embedding.android.FlutterAppCompatActivity

class MainActivity : FlutterAppCompatActivity() {

    override fun configureFlutterEngine(flutterEngine: FlutterEngine) {
        ...
        // Register WYF widget:
        flutterEngine
            .platformViewsController
            .registry
            .registerViewFactory(
                SitumMapFactory.CHANNEL_ID,
                SitumMapFactory(flutterEngine.dartExecutor.binaryMessenger, this)
            )
    }
}

4. Review your styles.xml file and make sure the application theme extends Theme.AppCompat.Light.DarkActionBar. Also remove the action bar in your theme:

<style name="NormalTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    ...
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
</style>

5. Add your Google Maps API Key to the AndroidManifest.xml file:

<meta-data
    android:name="com.google.android.geo.API_KEY"
    android:value="@string/google_api_key" />

iOS

The following steps have already been done for you in the example application of this project, but we list them as required documentation for a new project:

1. After including the dependecy on your project through Run pod install or pod update to bring the dependencies to your project.

2. In order for the wayfinding module to successfully activate positioning you will need to declare the following permissions in your app's Info.plist file:

<key>NSLocationWhenInUseUsageDescription</key>
	<string>Location is required to find out where you are</string>
<key>NSBluetoothPeripheralUsageDescription</key>
	<string>Bluetooth is required to find out where you are</string>
<key>NSLocationAlwaysUsageDescription</key>
	<string>Location is required to find out where you are</string>
<key>NSLocationAlwaysAndWhenInUseUsageDescription</key>
	<string>Location is required to find out where you are</string>
<key>NSBluetoothAlwaysUsageDescription</key>
	<string>Bluetooth is required to find out where you are</string>

Once included the app will ask the user for the appropriate permissions.

How does this plugin work?

This plugin uses Platform Views for both Android and iOS. WYF's PlatformView implementation ensures that only one instance of WYF can be loaded at any time. This is great for performance because the WYF load() is an expensive operation. Once WYF is loaded, it will not be loaded again and instead it will display the active module. As a consequence, there can only be one SitumMapView widget alive at a time.

This doesn't mean that you can only implement one SitumMapView widget in your app. It just means that only one of them can be alive at the same time: ensure that dispose() is called over any SitumMapView before initializing another one.

Navigator

Take care to keep your navigation stack clean. The following sequence will crash your application:

1. State A: app displays page A containing WYF.
2. Navigate to page B using Navigator.push(routeToB).
3. Navigate again to page A: Navigator.push(routeToA).
4. Crashes: the view returned from PlatformView#getView() was already added to a parent view.

To solve it:

• Fix the previous sequence calling Navigator.pop() instead of Navigator.push(routeToA).
• Or ensure that dispose() is called over A, for example replacing push with Navigator.pushReplacementNamed().

Versioning

Please refer to CHANGELOG.md for a list of notable changes for each version of the plugin.
