百度了几种解决方案 包括修改/android/app/ 下debug main 文件下xml文件的允许网络访问 但似乎不太管用 不太确定是否定位到了产生问题的原因

这是在下载Android工程依赖包时报错了，你用Android studio打开项目下的Android项目然后运行试试看能否正常下载这些依赖呢

  我试了一下 发现可以运行和打开模拟器 但是有时候打开也会出错 似乎是
  Caused by: org.gradle.api.internal.artifacts.ivyservice.DefaultLenientConfiguration$ArtifactResolveE
  这个报错 
  需要配置gradle相关的文件
  并且我的ios模拟器在Android studio里也运行不了flutter项目

  iOS的那个我看到了，需要先安装下CocoaPods

  我按照网上教程安装好了 但是gradle一直配置不好 现在在卸载Android studio重新下载安装
