I guess you are mixing two different packages. Both youtube_player_flutter and youtube_player_iframe have YoutubePlayerController. However, videoId only exists in youtube_player_flutter and params only exists in youtube_player_iframe. You can instead use...

Try YoutubePlayerScaffold instead of YoutubePlayer. ``` YoutubePlayerScaffold( controller: _youtubeController, aspectRatio: 16 / 9, builder: (context, player) { return SingleChildScrollView( child: Column( children: [player], )); }, ) ```

Same here.
