Flutter 颤振中出现网络错误（例如超时、连接中断或无法访问主机）

我用的是颤振，除了今天，一切都很好。现在，每当我尝试登录时，都会出现以下错误：网络错误（例如超时、连接中断或无法访问主机）在我的iOS模拟器上从FIREBASE发生。

这是在我的控制台中抛出的错误：

Challenge SecTrustResultType 5 for www.googleapis.com, properties: (
        {
          type = error;
          value = "Root certificate is not trusted.";
        }
)

今天我犯了同样的错误。你找到解决方案了吗？是的，我的firebase核心版本和Flatter firebase版本不匹配。我所做的是升级了颤振，一切都准备就绪。今天我犯了同样的错误。你找到解决方案了吗？是的，我的firebase核心版本和Flatter firebase版本不匹配。我所做的是升级了颤振，一切都准备就绪。
