I’m trying to parse one object from a Json response. My response.data is of type ‘_InternalLinkedHashMap<String, dynamic>’. I would like to transform it to the type of my object. So for doing that I use the method fromJson of my class.
Class code:
import 'dart:convert';
import 'package:.../stl/store_stl.dart';
class StoreSTLModel extends StoreSTL {const StoreSTLModel({
required String storeId,
required String storeName,
required String subContextUrl,
required List<dynamic> openingEvent,
required List<dynamic> closingEvent,
}) : super(
storeId: storeId,
storeName: storeName,
subContextUrl: subContextUrl,
openingEvent: openingEvent,
closingEvent:closingEvent ,
);
Map<String, dynamic> toMap() {
return <String, dynamic>{
'storeId': storeId,
'storeName': storeName,
'subContextUrl': subContextUrl,
'openingEvent': openingEvent.toList(),
'closingEvent': closingEvent.toList(),
};
}
factory StoreSTLModel.fromMap(Map<String, dynamic> map) {
return StoreSTLModel(
storeId: map['storeId'] as String ,
storeName: map["storeName"] as String,
subContextUrl: map["subContextUrl"] as String,
openingEvent: List<dynamic>.from(map["openingEvent"] as List<dynamic>),
closingEvent: List<dynamic>.from(map["closingEvent"] as List<dynamic>),
);
}
String toJson() => json.encode(toMap());
factory StoreSTLModel.fromJson(String source) => StoreSTLModel.fromMap(json.decode(source) as Map<String, dynamic>);
}the code of my request is as follow: (I’m using Dio package)
import 'package:.../app_constants.dart';
import 'package:dio/dio.dart';
import 'package:...stl/store_stl_model.dart';
class RemoteStoreSTLDataSource {
static dynamic apiSTLData;
static late final urlApiSTL = AppConstants.urlApiSTL;
//get store from api STL (for now store id is hardcode)
Future<StoreSTLModel> getStoreFromSTL() async{
if(apiSTLData == null){
apiSTLData = {};
try{
Response? response = await Dio().get(
urlApiSTL,
);
apiSTLData = response.data;
print('apiSTLData type response.data ${ apiSTLData.runtimeType}');
//prints: apiSTLData type response.data _InternalLinkedHashMap<String, dynamic>
}on Exception {
null;
print('apiSTLData Exception');
}
}
print('apiSTLData type response.data[store] ${apiSTLData['store'].runtimeType}');
//prints: apiSTLData type response.data[store] _InternalLinkedHashMap<String, dynamic>
return StoreSTLModel.fromJson(apiSTLData['store']);
}
}when I try to run, I’m having the error:
Unhandled Exception: type '_InternalLinkedHashMap<String, dynamic>' is not a subtype of type 'String'so I don’t understand why it is not being parsed. and I don’t understand why the response is of this type ‘_InternalLinkedHashMap<String, dynamic>’ I'm a beginner in Dart. Could you please help me to understand. Thanks in advance :)
