+Put the player in fullscreen mode.

+On iOS, this displays the video in a fullscreen view controller with controls.
+
+On Android ExoPlayer & MediaPlayer, this puts the navigation controls in fullscreen mode. It is not a complete fullscreen implementation, so you will still need to apply a style that makes the width and height match your screen dimensions to get a fullscreen video.
