VideoController constructor

VideoController(Player player, { VideoControllerConfiguration configuration = const VideoControllerConfiguration(), })

PlatformVideoController

This class provides the interface for platform specific VideoController implementations. The platform specific implementations are expected to implement the methods accordingly.

The subclasses are then used in composition with the VideoController class, based on the platform the application is running on.
