Flutter:应用程序在加密时卡住

问题描述

我在加密和解密视频文件以及加密视频文件时遇到问题。没有任何错误。但在加密和解密视频文件时卡住了。我使用异步方法。但它仍然卡住。我的代码如下。

加密:

Future sifrele() async {
    try {
      crypt.setOverwriteMode(AesCryptOwMode.on);
      encFilepath = await crypt.encryptFile(realPath + '/WhatCarCanYouGetForAGrand.mp4',realPath + '/video.mp4.aes');
      print('The encryption has been completed successfully.');
    } on AesCryptException catch (e) {
      if (e.type == AesCryptExceptionType.destFileExists) {
        print('The encryption has been completed unsuccessfully.');
      }
      return;
    }
  }

解密:

Future decrypting() async {
    var videos = File(realPath + "/ElephantsDream.mp4.aes");
    try {
      realPath = await crypt.decryptFile(realPath + '/video.mp4.aes',realPath + '/cozulen.mp4');
      print('The decryption has been completed successfully.');
    } on AesCryptException catch (e) {
      if (e.type == AesCryptExceptionType.destFileExists) {
        print('The decryption has been completed unsuccessfully.');
      }
      return;
    }
  }

谢谢。
