Flutter插件image_picker和flutter_quill TLS错误?

Question

前几天好好的flutter项目在自己的电脑上突然不能下载部分依赖了，明明都是同样的环境配置，同事的电脑没问题，自己家的电脑运行也没问题，问题就出在image_picker这个插件上，一直提示

Got TLS error trying to find package flutter_plugin_android_lifecycle at https://pub.flutter-io.cn

除了这个插件，flutter_quill也是同样的问题，

Got TLS error trying to find package html2md at https://pub.flutter-io.cn

只是提示不同。现在就是只能屏蔽这两个插件，相关的页面暂时不去碰。

网上查询了很多，内外网都查了，查到的几个方法也不行，尝试了以下方法，

• 修改镜像源，改了清华和交大的源，也不行，很奇怪的一点是，在项目文件夹内通过powershell运行pub get，连接到的是修改后的源，但是在vscode或者AS中，连接的还是修改前的https://pub.flutter-io.cn，清除了缓存也没变。另外，使用清华源提示

  使用交大源提示

• 防火墙什么的也给关了测试了。
• 系统也添加了pub的pem证书，DART_VM_OPTIONS也配置了。
• 电脑连接手机热点进行下载。

我现在甚至想重装系统了，但是重装的代价太大，是否有人碰到过类似问题，如何解决的呢。

从你提供的错误信息来看，问题似乎与Flutter插件的TLS连接有关。这可能是由于网络问题、代理设置、证书问题等导致的。下面是一些可能的解决步骤：

1. 检查网络连接：确保你的网络连接稳定，并且没有被防火墙或其他安全软件阻止。
2. 更换Flutter源：由于你提到修改镜像源后问题依旧存在，可以尝试更换为其他可靠的源，例如阿里云、七牛云等。
3. 检查代理设置：如果你在使用代理，请确保代理设置正确，并且代理服务器可以访问到Flutter的仓库。
4. 检查证书问题：你提到已经添加了pub的pem证书，并配置了DART_VM_OPTIONS，但问题仍然存在。可以尝试重新下载证书，并确保配置正确。
5. 清除缓存和构建文件：尝试清除Flutter的缓存和构建文件，然后重新运行flutter pub get。可以使用以下命令清除缓存：

flutter cleanflutter pub cache repair

6. 更新Flutter和Dart版本：你提到Flutter版本为3.19.5，Dart版本为3.3.3。可以尝试更新到最新版本，看看问题是否得到解决。
7. 尝试在其他环境中运行：如果以上步骤都无法解决问题，可以尝试在其他电脑或环境中运行你的项目，看看问题是否依旧存在。这有助于确定问题是否与特定环境有关。

如果以上步骤都无法解决问题，可能需要更深入地检查你的网络设置和Flutter配置。在这种情况下，考虑寻求Flutter社区或专业开发者的帮助可能是一个好的选择。
