LatLng class
Represents a geographical location using latitude and longitude coordinates.
This class extends PointX to provide additional functionalities specific
to geographical coordinates, including methods to work with different
coordinate formats and geospatial calculations.
Constructors
- LatLng.new(double lat, double lng, [double? elevation])
- Creates a LatLng instance with specified latitude, longitude, and optional elevation.
-
LatLng.fromList(List<
double> list) - Creates a LatLng instance from a List containing latitude, longitude, and optional elevation.
- LatLng.fromMap(Map map)
- Creates a LatLng instance from a Map containing latitude, longitude, and optional elevation.
- LatLng.fromSexagesimal(String sexagesimal)
-
Converts sexagesimal string into a lat/long value
factory
- LatLng.fromString(String latLngAsString)
- Creates a LatLng instance from a string representation of coordinates (e.g.: "40.7128,-74.0060").
