Updating the Delivery Person's Location in Firebase Once we have the delivery person's location we need to update it in Firebase. We can use the FirebaseDatabase class to achieve this. using Firebase.Database; namespace DeliveryTracker { public class DeliveryPersonLocation { private readonly FirebaseDatabase _database; public DeliveryPersonLocation() { _database = FirebaseDatabase.DefaultInstance; } public async Task UpdateLocation(Location location) { var reference = _database.GetReference(delivery_person_location); await reference.SetValueAsync(new { latitude = location.Latitude longitude = location.Longitude }); } } } Track the Delivery Person's Location in Real-time we need to track the delivery person's location in real-time. using Firebase.Database; namespace DeliveryTracker { public class DeliveryPersonLocation { private readonly FirebaseDatabase _database; public DeliveryPersonLocation() { _database = FirebaseDatabase.DefaultInstance; } public async Task TrackLocation() { var reference = _database.GetReference(delivery_person_location); await reference.OnValueChangedAsync((snapshot) => { var location = snapshot.GetValue (); // Update the map with the new location UpdateMap(location); }); } private void UpdateMap(Location location) { // Update the map with the new location var map = new Map(); map.MoveToRegion(new MapSpan(new Position(location.Latitude location.Longitude) 0.01 0.01)); } } } Install the Firebase NuGet package in your MAUI project.

using Firebase; namespace DeliveryTracker { public partial class App : Application { public App() { InitializeComponent(); FirebaseApp.InitializeApp(); } } } Delivery Person's Location We also need to get the delivery person's location. We can use the Location class to achieve this. using Xamarin.Essentials; namespace DeliveryTracker { public class DeliveryPersonLocation { public async Task GetLocation() { var location = await Geolocation.GetLocationAsync(); return location; } } }

To create a MAUI app that tracks the live location of a delivery person in real-time we can use Firebase as our backend.

Tuhin Paul · Answer

The app starts initializing Firebase. Periodically or based on specific events (e.g. a button press) the app retrieves the delivery person's current location and updates it in Firebase. The Firebase Realtime Database triggers updates in real-time for all clients listening to changes at the specified reference. The map view is updated to reflect the delivery person's new location providing a real-time tracking experience.
