I just learn how can i use BuiltValue in flutter. my implemented webservice with Chopper work fine before using this library.
now after changing to use BuiltValue i get error and i can't resolve this problem
error is:
_InternalLinkedHashMap' is not a subtype of type 'BuiltRegister'
my server get only mobile_number and this is json response structure:
{

}
]
}

}
i build BuiltRegister register with structure:
part 'built_register.g.dart';
abstract class BuiltRegister implements Built<BuiltRegister, BuiltRegisterBuilder> {
//@formatter:off
String get mobile_number;
@nullable String get message;
@nullable BuiltUser get userInformation;
@nullable int get status;
@nullable BuiltList<BuiltTickets> get tickets;
//@formatter:on
BuiltRegister._();
factory BuiltRegister([updates(BuiltRegisterBuilder b)]) = _$BuiltRegister;
static Serializer<BuiltRegister> get serializer => _$builtRegisterSerializer;
}
abstract class BuiltUser implements Built<BuiltUser, BuiltUserBuilder> {
//@formatter:off
String get mobile_number;
String get active;
@nullable String get name;
@nullable String get email;
@nullable String get avatar;
@nullable String get teammate;
@nullable String get experience;
@nullable String get age;
@nullable String get gender;
@nullable String get height;
@nullable String get weight;
@nullable String get insurance;
@nullable String get job;
String get created_at;
String get updated_at;
String get api_token;
//@formatter:on
BuiltUser._();
factory BuiltUser([updates(BuiltUserBuilder b)]) = _$BuiltUser;
static Serializer<BuiltUser> get serializer => _$builtUserSerializer;
}
abstract class BuiltTickets implements Built<BuiltTickets, BuiltTicketsBuilder> {
//@formatter:off
int get id;
String get subject;
String get description;
int get ticket_number;
int get priority;
int get section;
int get solved;
String get created_at;
String get updated_at;
BuiltUser get user;
@nullable BuiltReply get reply;
//@formatter:on
BuiltTickets._();
factory BuiltTickets([updates(BuiltTicketsBuilder b)]) = _$BuiltTickets;
static Serializer<BuiltTickets> get serializer => _$builtTicketsSerializer;
}
abstract class BuiltReply implements Built<BuiltReply, BuiltReplyBuilder> {
//@formatter:off
int get ticket_id;
String get reply;
String get created_at;
String get updated_at;
BuiltUser get user;
//@formatter:on
BuiltReply._();
factory BuiltReply([updates(BuiltReplyBuilder b)]) = _$BuiltReply;
static Serializer<BuiltReply> get serializer => _$builtReplySerializer;
}
build command in terminal return successful and i don't have any problem, now this is my Chopper implementation:
part 'api_service.chopper.dart';
@ChopperApi(baseUrl: '/api/v1')
abstract class DiabetistApiService extends ChopperService {
@Post(path: '/register')
Future<Response<BuiltRegister>> registerUser(@Body() BuiltRegister body);
static DiabetistApiService create() {
final client = ChopperClient(
baseUrl: 'http://www.example.com',
services: [
_$DiabetistApiService(),
],
converter: BuiltValueConvert(),
interceptors: [
HeadersInterceptor({'Content-Type': 'application/json'}),
HttpLoggingInterceptor(),
(Response response) async {
if (response.statusCode == 404) {
chopperLogger.severe('404 NOT FOUND');
}
}
]);
return _$DiabetistApiService(client);
}
}
and BuiltValueConvert interceptor implementation for Chopper:
class BuiltValueConvert extends JsonConverter {
@override
Request convertRequest(Request request) {
//@formatter:off
return super
.convertRequest(
request.replace(
body: serializers.serializeWith(
serializers.serializerForType(
request.body.runtimeType), request.body
)
)
);
//@formatter:on
}
@override
Response<BodyType> convertResponse<BodyType, singleItemType>(Response response,) {
final Response dynamicResponse = super.convertResponse(response);
final BodyType customBody = _convertToCustomObject(dynamicResponse.body);
return dynamicResponse.replace<BodyType>(body: customBody);
}
dynamic _convertToCustomObject<SingleItemType>(dynamic element) {
if (element is SingleItemType) return element;
if (element is List)
return _deserializerListOf<SingleItemType>(element);
else
return _deserialize<SingleItemType>(element);
}
BuiltList<SingleItemType> _deserializerListOf<SingleItemType>(List dynamicList) {
return BuiltList<SingleItemType>(
dynamicList.map((element) => _deserialize<SingleItemType>(element))
);
}
SingleItemType _deserialize<SingleItemType>(Map<String, dynamic> value) {
return serializers.deserializeWith(serializers.serializerForType(SingleItemType), value);
}
}
and this is how can i want to connecting to server, send and getting result:
final register = BuiltRegister((b) => b..mobile_number = mobileNumber);
final response = await Provider.of<DiabetistApiService>(context).registerUser(register);
when i try to print response i get error
Problem solved!!!
I changed
convertResponse<BodyType, singleItemType>
to
convertResponse<BodyType, SingleItemType>
