How to cast dynamic to T or List<T> - flutter

Question

I have a service to call api and some methods expects just Object and the rest expects list of objects. And I'm trying some tricks with generics but then errors in _get method with casting occurs.
// List
Future<List<ToDo>> getToDos() async {
final List<Map<String, dynamic>> response =
await _get<List<Map<String, dynamic>>>(url: "ToDos");
final List<ToDo> result =
response.map((data) => ToDo.fromJson(data)).toList();
return result;
//Object
Future<ToDo> getToDo() async {
final Map<String, dynamic> response =
await _get<Map<String, dynamic>>(url: "ToDo");
final ToDo result = ToDo.fromJson(response);
return result;
}
Future<T> _get<T>({
required String url,
}) async {
final Response response = await get(
Uri.https(_apiURL, url),
);
if (response.statusCode == 200) {
final T jsonResponse = json.decode(response.body) as T;
return jsonResponse;
} else {
throw Exception(response.body);
}
}
Error:
Exception has occurred. _CastError (type 'List<dynamic>' is not a subtype of type 'List<Map<String, dynamic>>' in type cast)
Is it even possible to solve it like I'm trying?
[Update]:
Solution:
Future<T> _get<T, K>({
required String url,
}) async {
final Response response = await get(
Uri.https(_apiURL, url),
);
if (response.statusCode == 200) {
final dynamic jsonResponse = json.decode(response.body);
if (jsonResponse is List) {
return List<K>.from(jsonResponse) as T;
} else {
return jsonResponse as T;
}
} else {
throw Exception(response.body);
}
}

There's a list function called cast. You can cast a dynamic list to List<Map<String, dynamic>> like this:
final aList=[]//your list;
final castedList=aList.cast<Map<String, dynamic>>();
