i am having issue while trying to access data using rss

Error message: **Unhandled Exception: type '_InternalLinkedHashMap<String, dynamic>' is not a subtyp e of type 'FutureOr<List>' **

import 'dart:convert';    import 'package:xml2json/xml2json.dart';  import 'package:http/http.dart' as http;    Future<List> rssToJson(String category,      {String baseUrl="https://www.hindustantimes.com/feeds/rss/"}) async {    var client = http.Client();    final myTransformer = Xml2Json();    return await client.get(baseUrl + category + '/rssfeed.xml').then((response) {      return response.body;    }).then((bodyString) {      myTransformer.parse(bodyString);      var json = myTransformer.toGData();      return jsonDecode(json)['rss']['channel']['item'];    });  }  

this is where i am trying to use the data received from rss

Map<String, List> newsData = Map<String, List>();    bool isLoading = true;    getData() async{      Future.wait([        rssToJson('topnews'),        rssToJson('india'),        rssToJson('world-news'),        rssToJson('business'),        rssToJson('sports'),        rssToJson('cricket'),        rssToJson('education'),        rssToJson('entertainment'),        rssToJson('lifestyle'),        rssToJson('health'),        rssToJson('books'),        rssToJson('trending'),      ]).then((value) {        value[0] = [];        value.forEach((element) {          value[0].addAll([...element ?? []]);        });        value[0].shuffle();        newsData['topnews'] = value[0].sublist(0, 10);        newsData['india'] = value[1];        newsData['world'] = value[2];        newsData['business'] = value[3];        newsData['sports'] = value[4];        newsData['cricket'] = value[5];        newsData['education'] = value[6];        newsData['entertainment'] = value[7];        newsData['lifestyle'] = value[8];        newsData['health-fitness'] = value[9];        newsData['books'] = value[10];        newsData['its-viral'] = value[11];        setState(() {          isLoading = false;        });      });    }  

I tried Future rssToJson as well but still not working...any help would be appreciated. Thanks in advance.
