Question

我正在调用一个post API，我必须在其中发送FormData，但是当我尝试解析该响应时收到响应后，我就遇到了异常。

static Future<String> versionApiRequest(String storeId, String deviceId) async {
    String versionApi = 'https://xxxxxxx/${storeId}/api_v5/version';
    print('$versionApi , $storeId');

    FormData formData = new FormData.from(
        {"device_id": deviceId, "device_token":"", "platform":"android"});
    Dio dio = new Dio();
    Response response = await dio.post(versionApi, data: formData,
        options: new Options(
        contentType: ContentType.parse("application/json")));
    print(response.data.toString());

    StoreData storeData = storeDataFromJson(response.data);
    //print("-------store.success ---${storeData.success}");
    return "";
  }

我遇到以下错误：

Unhandled Exception: type '_InternalLinkedHashMap<String, dynamic>' is not a subtype of type 'String'
    #0      ApiController.versionApiRequest (package:restroapp/src/networkhandler/ApiController.dart:43:54)
    <asynchronous suspension>

更改此项以将响应映射到模型类

var responseData = StoreData.fromJson(response.data);

Flutter-未处理的异常：类型为'_InternalLinkedHashMap <String，dynamic>
