当我点击我的网页视图中的一个按钮时，它会打开一个新的窗口，弹出网页，它会在Android设备中呈现，但在IOS中，它会在URL中给我“about：blank”，并显示空白屏幕，我已经尝试了不同的软件包，但这个问题仍然存在（webview_flutter，inappwebview）
而弹出应该呈现我得到的网址为“关于：空白”在IOS
我已经尝试了webview_flutter，inappwebview这两个软件包，并在info.plist中添加了所有属性

<key>NSAppTransportSecurity</key>
<dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
<key>NSAllowsArbitraryLoadsInWebContent</key>
<true/>
</dict>
