Utilize the Driving Insights API

Accessing some of the API classes that are mentioned on this page requires additional Sentiance SDK dependencies. See this page for more information.

On this page, you can find examples of how to query the Sentiance SDK for driving insights, and how to register to receive real time driving insights in your app, for completed transports.

public class DrivingInsightsUpdateReceiver: DrivingInsightsReadyDelegate {
    func subscribe() {
        Sentiance.shared.drivingInsightsReadyDelegate = self
    }
    
    public func onDrivingInsightsReady(insights: DrivingInsights) {
        // Handle the insights here (see the Query for Driving Insights
        // example above).
    }
}

To get driving insights updates even when your app is in the background, place the following code inside your app's entrypoint index.js file. If you're only interested in these updates when your app is foregrounded, place this code inside the appropriate UI code instead.

import SentianceDrivingInsights from "@sentiance-react-native/driving-insights";

// If you're subscribing to updates only in the foreground, make sure
// to call subscription.remove() inside your component's componentWillUnmount() function
const subscription = await SentianceDrivingInsights.addDrivingInsightsReadyListener(drivingInsights => {
    // Handle the insights here (see the Query for Driving Insights
    // example above).
});

Create a background.dart file under your project's lib folder with the following code:

background.dart

import 'package:sentiance_driving_insights/sentiance_driving_insights.dart';

@pragma('vm:entry-point')
void registerDrivingInsightsListener() async {
  WidgetsFlutterBinding.ensureInitialized();
  
  SentianceDrivingInsights.registerDrivingInsightsListener((drivingInsights) {
    // Handle the insights here (see the Query for Driving Insights
    // example above).
  });
}

Add the following code, depending on your target platform.

For iOS, add the following to your app delegate class:

AppDelegate.swift

import Flutter
import sentiance_driving_insights

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {

    override func application(
        _ application: UIApplication,
        didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
    ) -> Bool {
    
        // Other code
        
        SentianceDrivingInsightsPlugin.initializeListener(
            withEntryPoint: "registerDrivingInsightsListener",
            libraryURI: "package:your_app_package_name/background.dart"
        )
        
        return super.application(application, didFinishLaunchingWithOptions: launchOptions)
    }
}

For Android, add this code to your custom application class:

MainApplication.kt

import android.app.Application
import com.sentiance.driving_insights_plugin.DrivingInsightsPlugin

class MainApplication : Application() {
    override fun onCreate() {
        super.onCreate()
        
        // Other code

        val dartLibrary = "package:your_app_package_name/background.dart"
        DrivingInsightsPlugin.initializeListener(this, dartLibrary, "registerDrivingInsightsListener")
    }
}

If you're calling other APIs from the driving insights SDK or other 3rd party plugin APIs inside your registerDrivingInsightsListener Dart function, then you need to register these plugins with the Sentiance SDK. See this for more details.
