Convert Json of maps to list<Object> in flutter

I have a JSON like that

 [  
    {
        "id": "2a5",
        "employeeNumber": "101",
        "firstName": "Sachin",
        "lastName": "Agrawal"
    },
    {
        "id": "1f7",
        "employeeNumber": "151",
        "firstName": "Karsten",
        "lastName": "Andersen"
    },
]

I tried to parse the JSON like that

List<Employee> employees = (jsonDecode(response.data) as List)
          .map((data) => Employee.fromJson(data))
          .toList();

it causes the following error

List<dynamic>' is not a subtype of type 'String'

when I try to decode the JSON it causes the following error

Unhandled Exception: type 'List<dynamic>' is not a subtype of type 'String'

what is the proper way to parse this type of JSON?

You don't need to decode your response.data, it is already in list form. So instead of this:

List<Employee> employees = (jsonDecode(response.data) as List)
          .map((data) => Employee.fromJson(data))
          .toList();

try this:

List<Employee> employees = (response.data as List)
          .map((data) => Employee.fromJson(data))
          .toList();
