This is far from solving the issue, but for now as a workaround, you can blindly give Duration for the animation controller, adding duration: _totalAudioDuration??Duration(seconds: 3) inside FlutterStoryPresenter class.

so the code will look something like

        _animationController ??= AnimationController(
          vsync: this,
          duration: _totalAudioDuration??Duration(seconds: 3)//add this
        );

you might wanna do this on all the 3 places where AnimationController is set.
