[BUG] Random crash on iOS

[blendicavlad]

History check I confirm that i couldn't find a similar problem in the issue history.

Describe the bug Opening the video player crashed the app. The bug happened only once, on a real device. I couldn't reproduce the bug anymore. I only have the Firebase Crashalytics log at the time of the crash:

To Reproduce

1. Open the the player. (My video had a .MOV exension, in case it could be relevant)

*Example code

void _initVideoPlayer(String url) {
    BetterPlayerDataSource betterPlayerDataSource = BetterPlayerDataSource(
      BetterPlayerDataSourceType.network,
      url,
      cacheConfiguration: BetterPlayerCacheConfiguration(
        useCache: true,
        maxCacheFileSize: 250 * 1024 * 1024,
        maxCacheSize: 4 * 1000 * 1024 * 1024,
        key: widget.firebaseVideoResourceURL,
      ),
    );
    _betterPlayerController = BetterPlayerController(
      BetterPlayerConfiguration(
        aspectRatio: 16 / 9,
        expandToFill: false,
        fullScreenAspectRatio: 16 / 9,
        fit: BoxFit.fitHeight,
        eventListener: (event) {
          setState(() {
            if (event.betterPlayerEventType ==
                BetterPlayerEventType.openFullscreen) {
              _betterPlayerController?.setControlsEnabled(true);
              if (widget.controllerEventEmitter != null) {
                widget.controllerEventEmitter?.isFullscreen = true;
              }
            }
            if (event.betterPlayerEventType ==
                BetterPlayerEventType.hideFullscreen) {
              _betterPlayerController?.setControlsEnabled(false);
              if (widget.controllerEventEmitter != null) {
                widget.controllerEventEmitter?.isFullscreen = false;
              }
            }
            if (event.betterPlayerEventType == BetterPlayerEventType.pause) {
              _playPauseBtn = Icon(
                Platform.isIOS
                    ? CupertinoIcons.play_arrow_solid
                    : Icons.play_arrow_outlined,
                color: AppColors.accentColor,
                size: 28,
              );
            }
            if (event.betterPlayerEventType == BetterPlayerEventType.play) {
              _playPauseBtn = Icon(
                Platform.isIOS
                    ? CupertinoIcons.pause_solid
                    : Icons.pause_outlined,
                color: AppColors.accentColor,
                size: 28,
              );
            }
          });
        },
        autoPlay: widget.autoplay,
        looping: true,
        // autoDetectFullscreenAspectRatio: true,
        deviceOrientationsAfterFullScreen: [
          DeviceOrientation.portraitUp,
        ],
        controlsConfiguration: const BetterPlayerControlsConfiguration(
          showControlsOnInitialize: false,
          controlBarColor: Colors.transparent,
          loadingColor: AppColors.accentColor,
          backgroundColor: Colors.transparent,
          progressBarPlayedColor: AppColors.accentColor,
          enableQualities: false,
          enableSubtitles: false,
          enableAudioTracks: false,
        ),
        showPlaceholderUntilPlay: widget.placeholder != null,
        placeholder: widget.placeholder
      ),
      betterPlayerDataSource: betterPlayerDataSource,
    );
    _betterPlayerController?.setControlsEnabled(false);
  }
