  var loading = false;
  List<Record> dataModel = [];
  Future<Null> getData() async{    
    final responseData = await http.get("https://xxxxxxx.json");    
    if(responseData.statusCode == 200){
      Map<String, dynamic> map = jsonDecode(responseData.body);
      LinkedHashMap<String,dynamic> data = map["data"];
      List<dynamic> newData = data["Records"];        
      print("newData: $newData");
      setState(() {
        for(Map i in newData[1]){
          dataModel.add(Record.fromJson(i));
          print("newData: $data");
        }
        loading = false;
      });
    }
  }
  void initState() {
    // TODO: implement initState
    super.initState();
    getData();
  }
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Machine Test'),
      ),
      body: Container(
        child: loading? Center(
          child: CircularProgressIndicator()):
        ListView.builder(
            itemCount: dataModel.length,
            itemBuilder: (context,i){
              final nDataList = dataModel[i];
              return Container(
                child: Text(nDataList.title),
              );
            } ),
        ),
      );
  }

As Eldar said in the comment:

for(Map i in newData[1]){

needs to be

for(Map i in newData){
