flutter打包报错 error: resource android:attr/fontVariationSettings not found.

昨天升级flutter SDK到1.22，测试时没有任何问题，打包的时候报错了：

Execution failed for task ':janalytics:verifyReleaseResources'.
> A failure occurred while executing com.android.build.gradle.internal.tasks.Workers$ActionFacade
   > 1 exception was raised by workers:
     com.android.builder.internal.aapt.v2.Aapt2Exception: Android resource linking failed

看报错信息是janalytics这个插件有问题，然后查看了插件引用的compileSdkVersion版本是27，而项目的版本是30，然后把插件的版本和项目的compileSdkVersion同步就解决了问题
