I have the following json object
{
"notifications": [
{
"correspondenceId": "81",
"type": "notification",
"title": "Find Your Future at Indiana University",
"snippet": "",
"readFlag": "NO",
"date": "Delivered on: Jul 09, 2018 at 12:00 AM",
"readDate": "Read on: Apr 03, 2018 at 12:00 AM",
"icon": "message",
"color": "neutral"
},
{
"correspondenceId": "80",
"type": "notification",
"title": "My IU Experience",
"snippet": "",
"readFlag": "NO",
"date": "Delivered on: Jul 09, 2018 at 12:00 AM",
"readDate": "Read on: Apr 03, 2018 at 12:00 AM",
"icon": "message",
"color": "red"
},
{
"correspondenceId": "82",
"type": "notification",
"title": "Test RSVP",
"snippet": "",
"readFlag": "NO",
"date": "Delivered on: Jul 09, 2018 at 12:00 AM",
"readDate": "Read on: Apr 10, 2018 at 04:31 PM",
"icon": "message",
"color": "neutral"
}
]
}
I have created the following object model using built_value
import 'package:built_collection/built_collection.dart';
import 'package:built_value/built_value.dart';
import 'package:built_value/serializer.dart';
part 'notification.g.dart';
abstract class NotificationList
implements Built<NotificationList, NotificationListBuilder> {
BuiltList<NotificationElement> get notifications;
NotificationList._();
static Serializer<NotificationList> get serializer =>
_$notificationListSerializer;
factory NotificationList([updates(NotificationListBuilder b)]) =
_$NotificationList;
}
abstract class NotificationElement
implements Built<NotificationElement, NotificationElementBuilder> {
String get correspondenceId;
String get type;
String get title;
@nullable
String get snippet;
String get readFlag;
bool get derivedReadFlag {
return readFlag.contains("YES");
}
String get date;
@nullable
String get readDate;
String get icon;
String get color;
NotificationElement._();
static Serializer<NotificationElement> get serializer =>
_$notificationElementSerializer;
factory NotificationElement([updates(NotificationElementBuilder b)]) =
_$NotificationElement;
}
And the following seralizer for json deserialization:
import 'package:built_value/serializer.dart';
import 'package:built_value/standard_json_plugin.dart';
import 'package:sunapsis/datasource/dataobjects/login.dart';
import 'package:sunapsis/datasource/dataobjects/notification.dart';
part 'serializers.g.dart';
@SerializersFor([
Login,
NotificationList,
])
final Serializers serializers =
(_$serializers.toBuilder()..addPlugin(StandardJsonPlugin())).build();
The login object model worked fine and is working as expected but when I added the NotificationList to SerializersFor, the serializer.g.dart file started throwing errors. I am getting this error message for BuiltList in the serializers.g.dart file
Arguments of a constant creation must be constant expression
Invalid constant value
Undefined name 'BuiltList'
Undefined class 'ListBuilder'
On trying to compile I am getting this error which says the same thing
compiler message: lib/datasource/dataobjects/serializers.g.dart:24:15: Error: Getter not found: 'BuiltList'.
compiler message: BuiltList, const [const FullType(NotificationElement)]),
compiler message: ^
compiler message: lib/datasource/dataobjects/serializers.g.dart:25:21: Error: Method not found: 'ListBuilder'.
compiler message: () => new ListBuilder<NotificationElement>()))
compiler message: ^^^^^^^^^^^
Not sure where I am going wrong or what the issue could be. Using the following versions for built_value and built_collection
built_value: "^5.5.3"
built_collection: "^3.1.1"
build_runner: ^0.8.0
built_value_generator: ^5.5.0
This is the serializer.g.dart file generated:
// GENERATED CODE - DO NOT MODIFY BY HAND
part of 'serializers.dart';
// **************************************************************************
// BuiltValueGenerator

// ignore_for_file: always_put_control_body_on_new_line

Serializers _$serializers = (new Serializers().toBuilder()
..add(AuthProcess.serializer)
..add(Login.serializer)
..add(NotificationElement.serializer)
..add(NotificationList.serializer)
..addBuilderFactory(
const FullType(
BuiltList, const [const FullType(NotificationElement)]),
() => new ListBuilder<NotificationElement>()))
.build();
Any help will be greatly appreciated.
