How can i parse this json correctly?

Right now i am trying to parse a complex json output from my api. Before using pagination it was fine (i will give the code below) but right now i am using pagination and i can't figure out how to parse this code.

Json Output

{
"count":6,
"next":"http://127.0.0.1:8000/api/articles/?format=json&limit=2&offset=2",
"previous":null,
"results":[{"id":"6463e530-368e-45c6-97ec-0599018a27df","email":"[email protected]"}{"id":"7463e530-368e-45c6-97ec-0599018a27df","email":"[email protected]"}]
}

Before pagination it was like this:

[{"id":"6463e530-368e-45c6-97ec-0599018a27df","email":"[email protected]"},{"id":"7463e530-368e-45c6-97ec-0599018a27df","email":"[email protected]"}]

What i need to do is parse the post model inside "results". Here is my code

Json Parse Code

Future<List<Post>> FetchPosts(http.Client client,categoryconf) async {
  List<Post> posts;
  final response = await http.get("$SERVER_IP/api/articles/?format=json");
  final parsed = jsonDecode(response.body).cast<Map<String, dynamic>>();
  posts = parsed.map<Post>((json) => Post.fromJSON(json)).toList();
  return posts;
}

this is how you fetch data.

class Pagination{
  int count;
  String next;
  String previous;
  List<Post> results;
  Pagination({this.count,this.next,this.previous,this.results});

  factory Pagination.fromJson(Map<String, dynamic> json,) {
    if (json["results"] != null) {
      var results= json["results"] as List;
      List<Post> _results=
      results.map((list) => Post.fromJson(list)).toList();
      return Pagination(
        results: _results,
        count: json["count"] as int,
        previous: json["previous"] as String
        next: json["next"] as String
      );
    }
    return null;
  }
}
