load csv from assets and split with new Line

class CsvImp extends StatefulWidget {
  @override
  _CsvImp createState() => _CsvImp();
}

class _CsvImp extends State<CsvImp> {

  List<String> added = [];
  String currentText = "";
  List<String> csv = new List();
  GlobalKey<AutoCompleteTextFieldState<String>> key = new GlobalKey();

  @override
  void initState() {
    // TODO: implement initState
    super.initState();

    loadCSV();

  }

  @override
  Widget build(BuildContext context) {
    return new Scaffold(
        appBar: new AppBar(
          title: new Text("csv"),
        ),
        body: csv.length == 0 ? new Container() :
        new SimpleAutoCompleteTextField(
          key: key,
          suggestions: csv,
          decoration: InputDecoration(
            labelText: 'Name',
            hintText: 'Input Name',
            icon: Icon(Icons.person),
            isDense: true,
          ),
        ),

      );
  }

  Future<String> loadAsset(String path) async {
    return await rootBundle.loadString(path);
  }

  void loadCSV() {
    loadAsset('assets/file.csv').then((String output) {

      setState(() {
        csv = output.split("\n");
      });

    });
  }
}
