GeoPoint won't generate fromJson code

[luqmanhakem]

Describe the bug Hello. I tried to run flutter pub run build_runner build --delete-conflicting-outputs for this below code and this error occur.

Is this a bug or am I'm doing it wrong. Also, couldn't manage to find any open issue. Thanks in advance.

[SEVERE] json_serializable:json_serializable on lib/modules/splash/models/service/service.dart:

Could not generate `fromJson` code for `geopoint`.
To support the type `GeoPoint` you can:
* Use `JsonConverter`
  https://pub.dev/documentation/json_annotation/latest/json_annotation/JsonConverter-class.html
* Use `JsonKey` fields `fromJson` and `toJson`

To Reproduce

import 'package:cloud_firestore/cloud_firestore.dart';
import 'package:freezed_annotation/freezed_annotation.dart';
import 'package:sook/modules/splash/models/models.dart';

part 'service.g.dart';
part 'service.freezed.dart';

@freezed
abstract class Service with _$Service {
  const factory Service({
    @required String submittedAt,
    @required String approvedAt,
    @required String status,
    @required String name,
    @required String category,
    @required String subcategory,
    @required String description,
    @required String startPrice,
    @required String endPrice,
    @required String avgRating,
    @required String country,
    @required String state,
    @required String geohash,
    @required GeoPoint geopoint,
    @required List<String> images,
    @required Map<String, Day> availability,
    @required List<Review> reviewList
  }) = _Service;

  factory Service.fromJson(Map<String, dynamic> json) =>
      _$ServiceFromJson(json);
}

Expected behavior

• I would like to retrieve Firebase Cloud Firestore collection of GeoPoint field and map to this class

Thank you! Able to generate .g.dart file. Haven't test this but will closed the issue as for now.

Kudos to you!

so did you write a custom converter for geoPoint? Can you share the code? :)

Geopoints are natively supported by the ODM now. Just make sure you follow the docs and correctly setup the list of "JsonConverters" to include the built-in ones.
