hideControlsTimer doesn't work for customControls

I'm using Chewie to customize controls for a client. If I use the standard controls, when parameterizing hideControlsTimer it works. But if I use customControls, no.

My ChewieController is:
`_chewieController = ChewieController(
videoPlayerController: _videoPlayer,
aspectRatio: 16 / 9,
autoPlay: true,
showOptions: false,
showControls: true,
progressIndicatorDelay:
bufferDelay != null ? Duration(milliseconds: bufferDelay!) : null,
hideControlsTimer: const Duration(seconds: 3),
customControls: VideoControls(
controller: _videoPlayer,
fnPlay: _fnPlay,
fnPrev: _fnPrev,
fnNext: _fnNext,
fnSeek: _fnSeek,
fnFull: _fnFull,
),
);
}`
