Option to remove the overlay colour during hover but keep the controls

[Martin-QPT]

In Flutter Web the mouse over overlay stays for 3 seconds and is a black54. I'd like to see an ability to remove it and just show the controls on hover. Currently the only way to do this is to wrap the control in a Theme that has the platform set to iOS:

final themeData = Theme.of(context);
    return _chewieController != null && _chewieController!.videoPlayerController.value.isInitialized
        ? Theme(
            data: themeData.copyWith(platform: TargetPlatform.iOS),
            child: Chewie(
              controller: _chewieController!,
            ),
          )
        : const Center(
            child: CircularProgressIndicator(),
          );
  }
