<https://paste.ubuntu.com/p/9FwNMbDxKs/> this is my json data

<https://paste.ubuntu.com/p/yycQdpsHHM/> this is my model

<https://paste.ubuntu.com/p/wKgnfXy9tF/> this is my function in apiservice till now everything is fine but when i try to reach my json data like : 

```
List<Menu> menuler = List<Menu>();

@override

  Widget build(BuildContext context) {

    islemDonus = IslemDonus();

    islemDonus.anaMenuListeyiAl().then((value) {

      menuler.add(value[0].anagrupBaslik.toString());
      for (var i = 0; i < value.length; i++) {
        menuler.add(value[i].anagrupBaslik.toString());
      }
    });

```

it says:

```
The argument type 'String' can't be assigned to the parameter type 'Menu'.

```

but the value which comes from json data is Menu and as you can see i created my List why it is happening ?,
