Flutter：无法使用属性地理点生成 user.g.dart

Question

我想序列化用户 class 但是当我执行 flutter pub 运行 build_runner build 时位置会产生错误。我该如何解决？

用户class

 ...
 part 'user.g.dart';

@JsonSerializable()
class UserData {
  final String uid;
  late final String name;
  final String surname;
  final List<Location> location;

  UserData(
      {required this.uid,
      required this.name,
      required this.surname,
      required this.location});

  factory UserData.fromJson(Map<String, dynamic> json) => _$UserFromJson(json); 
  Map<String, dynamic> toJson() => _$UserToJson(this);
}

@JsonSerializable()
class Location {
  String locationName;
  GeoPoint point;

  Location({required this.locationName, required this.point});
  factory Location.fromJson(Map<String, dynamic> json) =>
      _$LocationFromJson(json);

  Map<String, dynamic> toJson() => _$LocationToJson(this);
}

Answer 1

在

location.g.dart

您可能需要在 _$LocationFromJson{}

中手动添加以下代码

point: json['geopoint'] as GeoPoint

Flutter: Could not generate user.g.dart with atribute geopoint
