I was working with reverse geocoding, where trying to store the user data with help of address model. However getting this error. I tried to add "?" sign while I am declaring variables in model adress class but it throws an exception.
Code of Address class:
class Address{
String? placeFormattedAddress;
String? placeName;
String? placeId;
Double lattitude;
Double longitude;
Address({this.placeFormattedAddress, this.lattitude, this.longitude, this.placeId, this.placeName});
}
code where problem is coming:
class placeSearcherMethods{ static Future searchCoodinateAddress(Position position, context ) async { String placeAddress = "";
var response = await placeSearcher.getRequest(url);
if (response != "Failed!!"){
placeAddress = response["results"][0]["formatted_address"];
Address userPickUpAddress = new Address();
userPickUpAddress.lattitude = position.latitude;
userPickUpAddress.longitude = position.longitude;
userPickUpAddress.placeName = placeAddress;
Provider.of<carpool_data>(context, listen: false).update_pickup_location_address(userPickUpAddress);
}
return placeAddress;
} }
Use double like double? lattitude;
class Address {
String? placeFormattedAddress;
String? placeName;
String? placeId;
double? lattitude;
double? longitude;
Address(
{this.placeFormattedAddress,
this.lattitude,
this.longitude,
this.placeId,
this.placeName});
}
And remove import 'dart:ffi';
