The location package is used to read the device's GPS position. You create an instance of the Location class and obtain the position through this instance. The location data comes as latitude and longitude.
final location = Location();
final data = await location.getLocation();
print(data.latitude);LocationData and latitude

final data = await location.getLocation();
print(data.latitude);
