Flutter :MediaQuery.of() called with a context that does not contain a MediaQuery

这个问题出现的情况是页面布局出现了问题
Flutter :MediaQuery.of() called with a context that does not contain a MediaQuery 报错

如果要使用MediaQuery 必须在MaterialApp 中使用，不然的话找不到

修改后的代码
Flutter :MediaQuery.of() called with a context that does not contain a MediaQuery 报错
这样就可以正常运行了
