WebViewPlatformController class

Interface for talking to the webview's platform implementation.

An instance implementing this interface is passed to the onWebViewPlatformCreated callback that is passed to WebViewPlatformBuilder#onWebViewPlatformCreated.

Platform implementations that live in a separate package should extend this class rather than implement it as webview_flutter does not consider newly added methods to be breaking changes. Extending this class (using extends) ensures that the subclass will get the default implementation, while platform implementations that implements this interface will be broken by newly added WebViewPlatformController methods.
