错误信息：

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':xxx:verifyReleaseResources'.
> A failure occurred while executing com.android.build.gradle.tasks.VerifyLibraryResourcesTask$Action
   > Android resource linking failed
     ERROR:/Users/xxx/xxx/xxx/intermediates/merged_res/release/values/values.xml:194: AAPT: error: resource android:attr/lStar not found.

所安装插件和当前项目 compileSdkVersion 不一致导致。如果你用的是 Android Studio ，左边项目文件区选择 External Libraries-Flutter Plugins，找到报错的插件，修改其 compileSdkVersion 和当前项目一致即可。

也可以找到插件的实际路径修改，插件实际安装路径：~/.pub-cache/hosted/pub.flutter-io.cn/，也有可能不是 pub.flutter-io.cn，看自己怎么配置的。

参考：

Execution failed for task ':xxxxxx:verifyReleaseResources'

flutter 打包 Execution failed for task ':xxx:verifyReleaseResources'. > A failure occurred
