所以我有一个应用程序，上传图像到ftp服务器使用此代码：

try {
    File fileToUpload = File(filePathPharmacy);

    await ftpConnect.connect();
    await ftpConnect.changeDirectory(
        "/public_html/XXXXXX/XXXXXX/main/assets/userImags");

    bool res =
        await ftpConnect.uploadFileWithRetry(fileToUpload, pRetryCount: 3);
    await ftpConnect.disconnect();
    print(res);
  } catch (w) {
    print("error : $w");
  }

解释：

filePathPharmacy => Is the Path of the file . Example :- /data/user/0/come.adeeb.smartbureau/app_flutter/b2042f2e-bd9e-4d91-8775-7b8e26d124886989878843844875758.jpg

XXXXXX => is my location on the server (I hade it for security)

成功了！我就能在FTP服务器上找到文件
但图像分辨率不好或它遭受奇怪的扭曲！

有办法解决吗？
