type 'int' is not a subtype of type 'String' in type cast json | decode Problem

I want to decode a large JSON but i get this error.´(type 'int' is not a subtype of type 'String' in type cast)

The return should look like this: 'IdJB' => 2, 'titel' => "lalalala",'datum' => 12052003,etc...

This is my Code.

Future<Map<String, dynamic>> lol() async {
  final response = await http.post(
      "http://www.bumsbirne.de/2/cool.lol.php", body: {
    "status": "1",
    "nam_ersteller": "Quyre",
    "nummer": 1,
  });
  var data = jsonDecode(response.body);
  
  print(data);
  return data;
}
lol();

Thats the Console

You are parsing the string as an Int. Try to follow the code below. Just convert all data into a string.

Future<Map<String, dynamic>> lol() async {
  final response =
      await http.post("http://www.bumsbirne.de/2/cool.lol.php", body: {
    "status": 1.toString(),
    "nam_ersteller": "Quyre".toString(),
    "nummer": 1.toString(),
  });
  var data = jsonDecode(response.body);

  print(data);
  return data;
}
