+`WebViewController`, `WebViewWidget`, `NavigationDelegate`, and `WebViewCookieManager` pass their
+functionality to a class provided by the current platform. Below are a couple of ways to access
+additional functionality provided by the platform and is followed by an example.
+
+1. Pass a creation params class provided by a platform implementation to a `fromPlatformCreationParams`
+   constructor (e.g. `WebViewController.fromPlatformCreationParams`,
