onPageCommitVisible property Null safety

(void Function?(InAppWebViewController controller, Uri? url)?) onPageCommitVisible

Called when the web view begins to receive web content.

This event occurs early in the document loading process, and as such you should expect that linked resources (for example, CSS and images) may not be available.

url represents the URL corresponding to the page navigation that triggered this callback.
