我正在开发一个扑动的应用程序。
我发现了一个样本扑动项目，所以民间它。但是项目...构建失败并显示以下日志消息。
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':app:preDebugBuild'.
> Android dependency 'androidx.core:core' has different version for the compile (1.0.0) and runtime (1.0.1) classpath. You should manually set the same version via DependencyResolution
* 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.
* Get more help at https://help.gradle.org

*******************************************************************************************
The Gradle failure may have been because of AndroidX incompatibilities in this Flutter app.
See https://flutter.dev/docs/development/packages-and-plugins/androidx-compatibility for more information on the problem and how to fix it.

Finished with error: Gradle task assembleDebug failed with exit code 1
该项目并不特别。 android部分，没有其他修改。它与“新扑动项目”完全相同。
我试了一下：
弹出错误时失败。我尝试使用“重构>迁移到android x”进行迁移，但它显示错误弹出窗口。错误弹出对我说至少使用compilesdkversion 28.但我已经使用了28 ..我该怎么办？......
但是使用不同的日志构建失败

我不知道该怎么办......
这让我累了...我只想编码......
我通过以下链接解决了这个问题：https://flutter.dev/docs/development/packages-and-plugins/androidx-compatibility
有2个迁移指南。
就我而言，“推荐”的解决方案不起作用......
但是，'不推荐'解决方案有效......
...
这是不容易的...
