Question

I am trying to fetch and parse the below response . I am successfull in receiving the json but unable to parse the array of objects . I am using serializable for this . kindly help me .
Following below is the model class
import 'package:coinbase_sockets/deriv_models/active_symbols_response.dart';
import 'package:json_annotation/json_annotation.dart';
part 'markets_response.g.dart';
#JsonSerializable()
class MarketsResponse {
#JsonKey(name: 'active_symbols')
List<ActiveSymbolsResponse> active_symbols;
MarketsResponse(this.active_symbols);
factory MarketsResponse.fromJson(Map<String,dynamic> data) {
print('##---------------------coming--------------------------');
var l = _$MarketsResponseFromJson(data);
print('##lrngth l'+l.toString());
return _$MarketsResponseFromJson(data);}
Map<String,dynamic> toJson() => _$MarketsResponseToJson(this);
}
Below is the generated class that i edited .
// GENERATED CODE - DO NOT MODIFY BY HAND
part of 'markets_response.dart';
// **************************************************************************
// JsonSerializableGenerator
// **************************************************************************
MarketsResponse _$MarketsResponseFromJson(Map<String, dynamic> json) {
**print('##---------------------market--------------------------'+json.toString()); receved upto here**
var mm= MarketsResponse(
json['active_symbols'] as List<ActiveSymbolsResponse>
);
**print('##---------------------mm--------------------------');this is not printed -means issue with mm**
return MarketsResponse(
json['active_symbols'] as List<ActiveSymbolsResponse>
);
}
Map<String, dynamic> _$MarketsResponseToJson(MarketsResponse instance) =>
<String, dynamic>{
'active_symbols': instance.active_symbols,
};

Try this
import 'package:json_annotation/json_annotation.dart';
part 'markets_response.g.dart';
#JsonSerializable()
class MarketsResponse {
#JsonKey(name: 'active_symbols')
List<ActiveSymbolsResponse> active_symbols;
MarketsResponse(this.active_symbols);
factory MarketsResponse.fromJson(Map<String, dynamic> json) => _$MarketsResponseFromJson(json);
Map<String, dynamic> toJson() => _$MarketsResponseToJson(this);
}
