flutter 报错external_file_lib_dex_archives\debug\out

周一刚上班，从新运行了上周五改完的app，结果遇到了下面的错误

本来上周五还好好的，就找了一下资料，发现网上的资料和解决办法很少，在此记录一下我这里成功的方案

I encountered this same error in a React Native project I am working on. I was able to resolve the issue through the following. Be sure to replace  below with your actual project name.

Within Android Studio, select File > Invalid Cache and Restart.
Open your project directory in your terminal.
rm -rf .gradle
rm -rf android/.gradle android/.idea
rm android/app/app.iml android/.iml
After doing this, I was able to open my project in Android Studio and successfully build. I had tried all but step 3 a few times without success, so my belief is that step 3 and the top-level .gradle directory in my project was the primary issue. I'm not sure how it got there.

One additional note, React Native projects place all of the Android-specific code inside an android directory. So, if your project is not a React Native project, and instead a traditional Android project, the paths I outlined for removal may be different (i.e. they wouldn't be underneath android/).

按理解就是gradle的问题，删了然后从新编译就好了
