WebViewPlatformController class abstract
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.
