近日，在flutter中愉快的学习着。
正吃着火锅唱着歌，莫名其妙给我来了一棒子。
报出下面一串东西。

*******************************************************************************************
The Gradle failure may have been because of AndroidX incompatibilities in this Flutter app.
See https://goo.gl/CP92wY for more information on the problem and how to fix it.

Finished with error: Gradle task assembleDebug failed with exit code 1
起初星号的括号，我以为还是错误的重要信息在这里，莫名的androidX经过百度，说是要确认targe api 28,还有其它设置要正确。但是，我的工程创建是勾选了兼容androidx的，所以应该已经配置androidx完善的了。因此，在从头看：
那么重点就在第一句Android resource compilation failed，然后指向第二句values.xml:133: error: :ui.item。这就很好解了
直接找到android目录下的values资源包，调整<ui.item>为<item>.也是莫民奇妙多了个ui，可能是因为我包命名？先是创建了ui,然后创建item。暂时未可知
