dart - 重定向的构造函数具有不兼容的参数

Question

我builtvalue在我的项目中使用我有一个json如下所示

{ "status": 1, "msg": "Success", "data": [ { "feeID": "25", "collectionID": "0", "type": 1, "category": "3 Fee", "schemeInfo": { "schemeID": 0, "schemeNo": 0, "schemeTxt": "", "schemeStatus": 1 }, "feeCode": "ISter Fee", "feeShortName": "", "basicAMT": "120000", "scholarshipInfo": { "scholarship": "0", "scholarshipAMT": 0, "scholarshipIDs": [] }, "dueDate": "2018-05-10", "lateFeeInfo": { "lateFeePerDay": "0", "lateDays": 28, "lateFeeAMT": 0 }, "taxInfo": { "tax": "18", "taxAMT": 21600, "taxAddedAMT": 141600 }, "grandAMT": 141600, "status": "2", "dateStatus": "1", "collectionDetailStatus": -1 }, { "feeID": "54", "collectionID": "0", "type": 1, "category": "4th Semester Tuition Fee", "schemeInfo": { "schemeID": 0, "schemeNo": 0, "schemeTxt": "", "schemeStatus": 1 }, "feeCode": "ISion Fee", "feeShortName": "", "basicAMT": "120000", "scholarshipInfo": { "scholarship": "0", "scholarshipAMT": 0, "scholarshipIDs": [] }, "dueDate": "2018-10-30", "lateFeeInfo": { "lateFeePerDay": "0", "lateDays": 28, "lateFeeAMT": 0 }, "taxInfo": { "tax": "18", "taxAMT": 21600, "taxAddedAMT": 141600 }, "grandAMT": 141600, "status": "2", "dateStatus": "1", "collectionDetailStatus": -1 } ], "wallet": { "walletID": "1483", "walletNo": "", "NTB": "25000.00", "WAB": "0.00", "status": "empty" } }

以下是我的模型类使用builtvalue

library fee_model;

import 'package:built_collection/built_collection.dart';
import 'package:built_value/built_value.dart';
import 'package:built_value/serializer.dart';

part 'fee_model.g.dart';

static Serializer get serializer => _$feeModelSerializer;

}

abstract class FeeData implements Built<FeeData, FeeDataBuilder> {
FeeData._();

factory FeeData([updates(FeeDataBuilder b)]) = _$FeeData;

@nullable

}

@nullable

static Serializer get serializer => _$walletSerializer;

}

abstract class SchemeInfo implements Built<SchemeInfo,SchemeInfoBuilder>{
SchemeInfo._();

factory SchemeInfo([updates(SchemeInfo si)]) = _$SchemeInfo;

@nullable
@BuiltValueField(wireName: 'schemeID')
int get schemeID;
@nullable
@BuiltValueField(wireName: 'schemeNo')
int get schemeNo;
@nullable
@BuiltValueField(wireName: 'schemeTxt')
String get schemeTxt;
@nullable
@BuiltValueField(wireName: 'schemeStatus')
int get schemeStatus;

static Serializer get serializer =>
_$schemeInfoSerializer;
}

abstract class ScholarshipInfo implements Built<ScholarshipInfo,ScholarshipInfoBuilder> {
ScholarshipInfo._();

factory ScholarshipInfo([updates(ScholarshipInfo si)]) = _$ScholarshipInfo;

@nullable
@BuiltValueField(wireName: 'scholarship')
String get scholarship;
@nullable
@BuiltValueField(wireName: 'scholarshipAMT')
int get scholarshipAMT;
@nullable
@BuiltValueField(wireName: 'scholarshipIDs')
BuiltList get scholarshipIDs;

static Serializer get serializer => _$scholarshipInfoSerializer;
}

abstract class LateFeeInfo implements Built<LateFeeInfo, LateFeeInfoBuilder>{
LateFeeInfo._();

factory LateFeeInfo([updates(LateFeeInfo lfi)]) = _$LateFeeInfo;

@nullable
@BuiltValueField(wireName: 'lateFeePerDay')
String get lateFeePerDay;

abstract class TaxInfo implements Built<TaxInfo,TaxInfoBuilder>{

factory TaxInfo([updates(TaxInfo ti)]) = _$TaxInfo;

@nullable
@BuiltValueField(wireName: 'tax')
String get tax;
@nullable
@BuiltValueField(wireName: 'taxAMT')
double get taxAMT;
@nullable
@BuiltValueField(wireName: 'taxAddedAMT')
double get taxAddedAMT;

static Serializer get serializer => _$taxInfoSerializer;

}

我运行了命令flutter packages pub run build_runner build然后我也收到错误消息redirected construcot has incompatible parameters

我附上了截图

我在课堂上不断收到错误，SchemeInfo,ScholarshipInfo,LateFeeInfo,TaxInfo但在课堂上没有出现错误Wallet,FeeData,FeeModelbuiltvalue

Answer 1

正如错误消息所说

factory SchemeInfo([updates(SchemeInfo si)]) = _$SchemeInfo;

应该

factory SchemeInfo([updates(SchemeInfoBuilder si)]) = _$SchemeInfo;
