使用老师的代码进行安卓打包，为什么出错？

Question

Warning: there were 12 unresolved references to classes or interfaces.

         You may need to add missing library jars or update their versions.

         If your code works fine without the missing classes, you can suppress

         the warnings with '-dontwarn' options.

         (http://proguard.sourceforge.net/manual/troubleshooting.html#unresolvedclass)

Warning: there were 2 unresolved references to library class members.

         You probably need to update the library versions.

* Try:

Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

The Gradle failure may have been because of AndroidX incompatibilities in this Flutter app.
