What is the distanceFilter parameter unit (meter or ...) in getLocationStream()?!

[CoreLocation] This method can cause UI unresponsiveness if invoked on the main thread. Instead, consider waiting for the -locationManagerDidChangeAuthorization:callback and checkingauthorizationStatus first.

Hello,

This plugin is great but there's one issue with Android. The location stops streaming in the background because the AlarmManager is not implemented.

I've implemented a workaround to fix this, but it would be great if it worked out of the box.

Thank you.

Is there any way to get the full nmea message using this plugin?

why this permission is required?

any idea? @Dev-hwang

Note: It works fine if calling on the main isolate.

this package supports background location updates even if the app is killed ?

Hi
When running FlLocation.getLocation(timeLimit: const Duration(seconds: 10)); in background using flutter_foreground_task, below exception occurs

Code:

reqResult = await FlutterForegroundTask.startService(
        notificationTitle: Strings.labelTrackLocationService,
        notificationText: Strings.msgTrackingLocation,
        callback: startCallback,
      );

void startCallback() {
  FlutterForegroundTask.setTaskHandler(MovementTrackingServiceHandler());
}

class MovementTrackingServiceHandler {
   _getCurrentLocation() {
          Location? location;
          try {
            location = await fl.FlLocation.getLocation(timeLimit: const Duration(seconds: 10));
          } catch (e) {
            debugPrint('$e');
          }
    }
}

java.lang.IncompatibleClassChangeError: Found interface com.google.android.gms.location.SettingsClient, but class was expected (declaration of 'com.google.android.gms.location.SettingsClient' appears in /data/app/~~n6Huw2QsDW-xwP2Tie6VxQ==/com.azooz.driverr-OKSmBNpK8FV8oWawPK30Hw==/base.apk)

Version 1.2.2 works well on Android but does not work on iOS.

Version 2.0.0 or newer works on iOS but does not work on Android.

If I install version 2.0.0 or newer, my splashart takes almost 1 minute to come out.

Hello,
Do you plan to add a way to ask the user to enable the GPS with a dialog (not talking about permissions, but about enabling the GPS service, the one you can check with FlLocation.isLocationServicesEnabled).
AFAIK, the only way to do this now is to send the user to the general settings.

Thanks for the plugin, cheers!
