Use case

Since iOS 16.4, the Web Inspector feature is disabled by default.
Therefore, to use Web Inspector, need to change the value of isInspectable.

Proposal

Starting from iOS version 16.4, it is now possible to change the value of the isInspectable property in WKWebView.

Here is a blog post from WebKit that discusses this

Apple Developer Forums thread (iOS 16.4 webview can not debug in safari web inspector)
https://developer.apple.com/forums/thread/727049

so need to implement the ability to change the isInspectable property of WKWebView in the webview_flutter_wkwebview package.
