How to save current location? - xamarin.forms

Question

I have a question. I am working on mobile app where my user can store experience from trip by loggin current location.
I am connected to SQLite fo now and I am just exploring the Geolocator nuget from James Monemagno. SO far I can get the pin on map with current location, but I am unsure how to store the location in databse. I guess it wont be"position" and it must be Latitude and Longitude but then how will i get again the picture with the pin displayed under my post? Do you guys have some experience?
Public clas NoteViewMode : BaseViewModel
{
/////
private string _location;
public string Location
{
get { return _location; }
set
{
_location = value;
OnPropertyChanged();
}
}
public double _latitude;
public double Latitude
{
get { return _latitude; }
set
{
_latitude = value;
OnPropertyChanged();
}
}
private double _longitude;
public double Longitude
{
get { return _longitude; }
set
{
_longitude = value;
OnPropertyChanged();
}
}
}
public Map()
{
InitializeComponent();
GetPremissions();
BindingContext = ViewModel = new AdLogEntryViewModel();
}
private async void GetPremissions()
{
try
{
var status = await CrossPermissions.Current.CheckPermissionStatusAsync(Plugin.Permissions.Abstractions.Permission.LocationWhenInUse);
if (status != Plugin.Permissions.Abstractions.PermissionStatus.Granted)
{
if (await CrossPermissions.Current.ShouldShowRequestPermissionRationaleAsync(Plugin.Permissions.Abstractions.Permission.LocationWhenInUse))
{
await DisplayAlert("We need location", "", "Ok");
}
var result = await CrossPermissions.Current.RequestPermissionsAsync(Plugin.Permissions.Abstractions.Permission.LocationWhenInUse);
if (result.ContainsKey(Plugin.Permissions.Abstractions.Permission.LocationWhenInUse))
status = result[Plugin.Permissions.Abstractions.Permission.LocationWhenInUse];
}
if (status == Plugin.Permissions.Abstractions.PermissionStatus.Granted)
{
locationsMap.IsShowingUser = true;
hasLocationPermission = true;
GetLocation();
}
else
{
await DisplayAlert("Location denied", "", "");
}
}
catch (Exception ex)
{
await DisplayAlert("erroe", ex.Message, "ok");
}
}
protected override async void OnAppearing()
{
base.OnAppearing();
if (hasLocationPermission)
{
var locator = CrossGeolocator.Current;
locator.PositionChanged += Locator_PositionChanged;
await locator.StartListeningAsync(TimeSpan.Zero, 100);
}
GetLocation();
}
protected override void OnDisappearing()
{
base.OnDisappearing();
CrossGeolocator.Current.StopListeningAsync();
CrossGeolocator.Current.PositionChanged -= Locator_PositionChanged;
}
void Locator_PositionChanged(object sender, Plugin.Geolocator.Abstractions.PositionEventArgs e)
{
MoveMap(e.Position);
}
private async void GetLocation()
{
if (hasLocationPermission)
{
var locator = CrossGeolocator.Current;
var position = await locator.GetPositionAsync();
MoveMap(position);
}
}
private async void MoveMap(Position position)
{
var center = new Xamarin.Forms.Maps.Position(position.Latitude, position.Longitude);
var span = new Xamarin.Forms.Maps.MapSpan(center, 1, 1);
locationsMap.MoveToRegion(span);
}

Answer 1

you can programmatically add a Pin to a Map
Pin pin = new Pin
{
Label = "Santa Cruz",
Address = "The city with a boardwalk",
Type = PinType.Place,
Position = new Position(36.9628066, -122.0194722)
};
map.Pins.Add(pin);
