Does chewie honor the `closedCaptionFile` in VideoPlayerController?

[http600]

I need to provide CC/Subtitles in the way of srt file, I found it is supported in VideoPlayerController

VideoPlayerController.networkUrl(Uri.parse(widget.playList),
        closedCaptionFile: _loadCaptions())

but It was not coming in the player, how should I give srt content to chewie player?
