Flutter 我正在尝试加载动态url作为初始url，而不是在webview中加载。若我将url放入tem var，并使用temp作为初始url，那个么它就会工作

在这里，我试图在webview中加载深度链接，首先在google中输入深度链接并将其重定向到应用程序，然后在webview中加载深度链接。如果我在webview中放置静态URL，比如var temp=“www.google.com”，然后使用temp var作为初始URL，它将加载google in应用程序。但我尝试将深度链接变量复制到字符串变量中，并在webview中使用临时变量作为初始URL，它不会在webview中加载动态链接。甚至我也将深度链接变量转换为字符串（将URI类型转换为字符串）
