I have a method, fetches some data from url and gets json array response like

```
Future<List<Images>> getData(String url) async {
    var response = await http.get(Uri.parse(url));
    return List<Images>.from(jsonDecode(response.body).map((x) => Images.fromJSON(x)));
}
response.body => [{"name":"img1","campaign_image_url":"http:\/\/xx.xxx.xxx.xxx\/development\/img1.jpg"},{"name":"img2","campaign_image_url":"http:\/\/xx.xxx.xxx.xxx\/development\/img2.jpg"}]

```

I have a Custom Object Called Images like

```
class Images {
  final String name;
  final String url;

  Images({required this.name, required this.url});

  Images.fromJSON(Map<String, String> json)
      : name = json['name']!,
        url = json['campaign_image_url']!;
}

```

I am using FutureBuilder to call a method `getData()` and loads data dynamically like

```
FutureBuilder<List<Images>>(
  future: getData(url),
  builder: (ctx, AsyncSnapshot<List<Images>> snapshot){
    if (snapshot.hasError) print(snapshot.error); //type '_InternalLinkedHashMap<String, dynamic>' is not a subtype of type 'Map<String, String>'
    if (snapshot.hasData) print(snapshot.data);
    return Container();
  }
)

```

Not able to get the data in `FutureBuilder` using `snapshot` and it is throwing snapshot error like `type '_InternalLinkedHashMap<String, dynamic>' is not a subtype of type 'Map<String, String>'`

I tried these

* [Map List of objects from a Json response to a List in flutter](https://stackoverflow.com/questions/64583151/map-list-of-objects-from-a-json-response-to-a-list-in-flutter)
* [Flutter future builder to list](https://stackoverflow.com/questions/71218223/flutter-future-builder-to-list)

I am expecting something like `List<Images> lst = snapshot.data`. But Something is missing and throwing an error, I can't figure it out
