Plugin.Maui.GeoLocator 1.0.3

Plugin.Maui.GeoLocator

NuGet

A .NET MAUI plugin for Android and iOS that provides:

• On-demand location retrieval
• Start / stop location tracking
• Reverse geocoding
• Optional logging

Install

Package: https://www.nuget.org/packages/Plugin.Maui.GeoLocator

dotnet add package Plugin.Maui.GeoLocator

Or reference the project:

<ProjectReference Include="..\src\Plugin.Maui.GeoLocator\Plugin.Maui.GeoLocator.csproj" />

Host app setup

Android

Declare location permissions in Platforms/Android/AndroidManifest.xml:

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

iOS

Add usage descriptions to Platforms/iOS/Info.plist:

<key>NSLocationWhenInUseUsageDescription</key>
<string>This app needs your location to show where you are.</string>

For background tracking, also add always-authorization text and the location background mode.

Register the plugin

builder
    .UseMauiApp<App>()
    .UseGeoLocator(options =>
    {
        options.EnableLogging = true;
    });

Resolve IGeoLocator from dependency injection, or use GeoLocator.Current.

Usage

On-demand location

var location = await GeoLocator.Current.GetCurrentLocationAsync(new LocationRequest
{
    Accuracy = LocationAccuracy.Best,
    Timeout = TimeSpan.FromSeconds(20)
});

Last cached fix:

var last = await GeoLocator.Current.GetLastKnownLocationAsync();

Start and stop tracking

var locator = GeoLocator.Current;

locator.LocationChanged += (_, e) =>
{
    var position = e.Location;
};

locator.LocationError += (_, e) =>
{
    Console.WriteLine(e.Message);
};

await locator.StartTrackingAsync(new TrackingOptions
{
    Accuracy = LocationAccuracy.High,
    MinimumTime = TimeSpan.FromSeconds(2),
    MinimumDistanceMeters = 5
});

await locator.StopTrackingAsync();

Reverse geocoding

var addresses = await GeoLocator.Current.ReverseGeocodeAsync(
    latitude: 47.6062,
    longitude: -122.3321);

foreach (var address in addresses)
    Console.WriteLine(address.FormattedAddress);

Logging

GeoLocator.Current.EnableLogging(true);
GeoLocator.Current.EnableLogging(true, new DebugGeoLocatorLogger());
GeoLocator.Current.EnableLogging(false);

When UseGeoLocator(options => options.EnableLogging = true) is used, the plugin also writes through ILogger if the host app registered one (for example builder.Logging.AddDebug()).

Sample

samples/GeoLocator.Sample is a MAUI app that exercises all four features. Deploy it to an Android emulator/device or an iOS simulator/device with location enabled.

dotnet build src/Plugin.Maui.GeoLocator/Plugin.Maui.GeoLocator.csproj
dotnet build samples/GeoLocator.Sample/GeoLocator.Sample.csproj -f net10.0-android

Notes

• Tracking is designed for foreground use. Android background tracking requires a host-app foreground service. iOS background tracking requires AllowBackgroundUpdates = true plus the location background mode.
• The plugin requests when-in-use location permission at runtime.
• net10.0 is included so shared code can reference the package. Location APIs throw GeoLocatorException (FeatureNotSupported) on that target.

Support

If this plugin saved you a weekend of native plumbing, consider buying me a coffee. Your support keeps it maintained, documented, and free.

This library stays open source. A coffee helps cover time for bug fixes, new features, and docs.
