How to get the frame rate?

[bdlukaa]

This is the code that I use to get the FPS of the video, but it always return 0.0. How is the correct way to get the FPS?

  @override
  double get fps {
    if (!isPi || player == null) return 0.0;

    return player
            ?.getMediaInfo()
            ?.video
            ?.firstOrNull
            ?.codec
            .frameRate
            .toDouble() ??
        0.0;
  }
