放置多提供商后如何修复死代码错误？

Question

错误信息：

Try removing the code, or fixing the code before it so that it can be reached.

我该如何解决这个问题？我尝试了所有我不能做的事情。

I need the MaterialApp to appear because it is part of the application and I cannot remove this part of the code because it is the main screen of the application.

改成这样：
