flutter 使用 dio 上传文件 找不到路径,不论是虚拟机还是连接手机调试

Question

  _upLoadImage(String path) async {
    FormData formData = FormData.fromMap(
        {"file": MultipartFile.fromFile(path, filename: "upload.txt")});

    Dio dio = new Dio();
    var respone = await dio.post(
        url,
        data: formData);
    if (respone.statusCode == 200) {}
  }
