network permission，access the network address

After the first installation of IOS mobile phone obtains the network permission, the page cannot be reloaded. You need to exit the app to access the network address normally.

No files or tests are named. Start by reproducing the first-install iOS network-permission flow in the Flutter WebView plugin, then trace the native WebView handling around page reload and network access. Done means the page can reload and access the network address immediately after permission is granted, without restarting the app.
