Primary player

As this plugin is designed for a VOD-type application, the plugin has the concept of a "primary" player. The plugin guarantees a primary player during initialization. This makes it easy for flutter to know which player to use by default across your app. The primary player also has some extra superpowers:

always available: cant be disposed and is initialized on startup
it controls what's shown in the notification center
it automatically transfers the current video to chromecasts when you start a session (technical details here).
cast sessions will automatically claim the primaryPlayer (so you don't need extra logic for handling the cast sessions)

// The primary player is automatically initialized on startup
// It's accessible statically via BccmPlayerController.primary:
final controller = BccmPlayerController.primary;

// Change video with replaceCurrentMediaItem
await controller.replaceCurrentMediaItem(
      MediaItem(
        url: 'https://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4',
        mimeType: 'video/mp4',
        metadata: MediaMetadata(title: 'Apple advanced (HLS/HDR)'),
      ),
    );

// Display as usual
final widget = BccmPlayerView(controller);

// You don't need to (and actually can't) dispose the primary player.
if (!controller.isPrimary) controller.dispose();
