我无法让 renderflex 继续运行

问：

我真的是fluuter的新手。这是我下面的代码。我尝试制作一个个人资料页面，但后来简历和其他东西溢出来，我无法让它显示在另一行下方的一行。A您的帮助将不胜感激。

Widget build(BuildContext context) {
    return WillPopScope(
      onWillPop: () async { Navigator.push(context, PageRouteBuilder(pageBuilder: (context,animation1,animation2)=>Homescreen(),transitionDuration: Duration.zero,reverseTransitionDuration: Duration.zero)); return true; },

这是配置文件页面的外观，在此处输入图像描述

我尝试在它周围添加一个扩展的小部件，我尝试给文本一个maxline功能，我尝试为文本设置溢出参数，但似乎没有任何效果。
