未定义命名参数“ child”。在Center（）构造函数中 [英] The named parameter 'child' isn't defined. in Center() constructor

问题描述

我今天进行了Flutter升级，现在出现一个错误，提示-[dart]未定义命名参数 child。该项目是新创建的，并且未更改默认代码，但仍具有相同的错误：

I ran flutter upgrade today, and now I am getting an error that says- [dart] The named parameter 'child' isn't defined. The project is newly created and the default code is untouched, but it still has the same Error:

推荐答案

实际上，我重新安装了flutter SDK以解决该问题。几天后，发生了相同的错误，但是我开始将鼠标悬停在红线上，一分钟后，该错误被自动解决。我猜一旦打开IDE，SDK将与Internet连接以检查所有库和语法内容。

Actually, I reinstalled the flutter SDK to solve the problem. After a few days, the same error occurred, but then I Started hovering over the red line, after a minute, the error was solved automatically. I guess the SDK connects with internet to check for all the libraries and syntax stuff once we open the IDE.
