iOS-specific methods can be called using the `InAppWebViewController.ios` attribute. Static methods can be called using the `IOSInAppWebViewController` class directly.
* `createPdf({IOSWKPDFConfiguration? iosWKPdfConfiguration})`: Generates PDF data from the web view’s contents asynchronously.
* `createWebArchiveData`: Creates a web archive of the web view’s current contents asynchronously.
* `hasOnlySecureContent`: A Boolean value indicating whether all resources on the page have been loaded over securely encrypted connections.
* `reloadFromOrigin`: Reloads the current page, performing end-to-end revalidation using cache-validating conditionals if possible.
* `static handlesURLScheme(String urlScheme)`: Returns a Boolean value that indicates whether WebKit natively supports resources with the specified URL scheme.
