Thanks for this really well explained tutorial... Unfortunately it doesn't work in my example. No matter what I try, I get unhandled exceptions... Unhandled Exception: type 'Null' is not a subtype of type 'Map<String, dynamic>'. Maybe it's the junction tables. I'm currently working with Strapi Headless CMS and the REST API with the ?populate filter option shows me all the data that Flutter doesn't seem to recognize

Thank you for this course is it really helpful. here is another way

"class UserLocation {
final String city;
final String state;
final String country;
final String postcode;
final LocationCoordinate coordinates;
final LocationStreet street;
final LocationTimezone timezone;

UserLocation(
{required this.city,
required this.state,
required this.country,
required this.postcode,
required this.coordinates,
required this.street,
required this.timezone});

factory UserLocation.fromMap(Map<String, dynamic> json) {
return UserLocation(
city: json['city'],
state: json['state'],
country: json['country'],
postcode: json['postcode'].toString(),
coordinates: LocationCoordinate.fromMap(json['coordinates']),
street: LocationStreet.fromMap(json['street']),
timezone: LocationTimezone.fromMap(json['timezone']),
);
}
}

class LocationCoordinate {
final String latitude;
final String longitude;

LocationCoordinate({
required this.latitude,
required this.longitude,
});
factory LocationCoordinate.fromMap(Map<String, dynamic> json) {
return LocationCoordinate(
latitude: json['latitude'],
longitude: json['longitude'],
);
}
}

class LocationStreet {
final int number;
final String name;

LocationStreet({
required this.number,
required this.name,
});
factory LocationStreet.fromMap(Map<String, dynamic> json) {
return LocationStreet(
number: json['number'],
name: json['name'],
);
}
}

class LocationTimezone {
final String offset;
final String description;

LocationTimezone({
required this.offset,
required this.description,
});

factory LocationTimezone.fromMap(Map<String, dynamic> json) {
return LocationTimezone(
offset: json['offset'],
description: json['description'],
);
}
}"
