Flutter 我在AndroidManifest.xml中遇到了太多错误。我怎样才能解决它们？

以下是我的代码： 我得到的错误是：

未解析的类“应用程序”

属性：此处不允许使用图标

未解析的类“MainActivity”

属性：此处不允许启动模式

属性：此处不允许使用主题

属性：此处不允许配置更改

属性android:此处不允许硬件加速

属性android:此处不允许WindowsOfInputMode

您可以一个接一个地解决这些问题，并一路学习；）但是怎么做呢？这就是问题所在：）展示你所做的努力，以及你在解决这些问题时遇到的错误。不要期望所有8个错误都有现成的解决方案。。。显示您的努力。@sourabhjambale，您可以忽略这些错误并继续构建。它会成功的。

<!-- The INTERNET permission is required for development. Specifically,
     flutter needs it to communicate with the running application
     to allow setting breakpoints, to provide hot reload, etc.

<!-- io.flutter.app.FlutterApplication is an android.app.Application that

     In most cases you can leave this as-is, but you if you want to provide
     additional functionality it is fine to subclass or reimplement
     FlutterApplication and put your custom class here. -->
