报文信息：

FAILURE: Build failed with an exception.
* What went wrong:
A problem occurred configuring project ':connectivity_plus'.
> Could not create an instance of type com.android.build.api.variant.impl.LibraryVariantBuilderImpl.
   > Namespace not specified. Specify a namespace in the module's build file. See https://d.android.com/r/tools/upgrade-assistant/set-namespace for information about setting the namespace.
     If you've specified the package attribute in the source AndroidManifest.xml, you can use the AGP Upgrade Assistant to migrate to the namespace value in the build file. Refer to https://d.android.com/r/tools/upgrade-assistant/agp-upgrade-assistant for general information about using the AGP Upgrade Assistant.

BUILD FAILED in 2s
Running Gradle task 'assembleRelease'...                            3.0s
Gradle task assembleRelease failed with exit code 1

问题原因：

可以看到报错信息为connectivity_plus 的命名空间问题导致，这里我们flutter的安卓项目下的gradle实际上是不用改的。故此这个报错肯定是版本过低的bug或者其他原因导致。

解决办法：

说明：升级我们的connectivity_plus 这个包的版本以此修复这个问题。

修复后尝试打包，输出结果正常：
