flutter http post empty on server side

Question

i try to send post request in flutter app like

static Future<List<dynamic>?> postData(data) async {
    var body = json.encode(data);
    Map<String, String> headers = {"Content-Type": "application/json"};
    var url = Uri.http(Config.api, Config.endPoint);
    var response = await client.post(url, headers: headers, body: body);
    if (response.statusCode == 201) {
      var data = jsonDecode(response.body);
      return data;
    }
    return null;
  }

this is data was sent

Map data = {
      'database': 'school_control_ykt',
      'table': 'tablets_helper',
      'place': place,
      'reason': reason,
      'teacher': teacher,
      'name': name,
      'id_group': id_group
    };
postData(data);

but in server side (php) $_POST are empty

i wanna know why $_POST are empty when a send the request in flutter app but in Postman request is send successfully and $_POST have data enter image description here

Use MultipartRequest as API expect multipart/form-data. Something like this:

var request = MultipartRequest('POST', uri)
  ..fields = data
var response = await request.send();
