try to set the playerLoadingFallback, but occasionally it didn't work

version list: Flutter 3.16.9 flick_video_player: ^0.7.0 video_player: ^2.8.2

demo:

FlickVideoPlayer(
        flickManager: flickManager,
        flickVideoWithControls: FlickVideoWithControls(
          videoFit: BoxFit.contain,
          controls: SafeArea(
            child: FlickPortraitControls(
              iconSize: 22,
              fontSize: 14,
              progressBarSettings: FlickProgressBarSettings(
                padding: const EdgeInsets.symmetric(
                  vertical: 10,
                ),
              ),
            ),
          ),
          // TDLoading is a custom style loading widget
          playerLoadingFallback: const Center(
            child: TDLoading(
              size: TDLoadingSize.medium,
              icon: TDLoadingIcon.circle,
              iconColor: Color.fromRGBO(214, 224, 244, 1),
            ),
          ),
        ),
      )

But it still shows the purple one. What should I do?
