Can not open file video from VideoThumbnail after trim video on IOS( iPhone 12 ).

[commond140]

I use video_thumbnail: ^0.5.3 and video_trimmer: ^2.0.1 It can not open file when edited video from video_trimmer. If open video but did not trim video and save. video_thumbnail can open the file.

some code from video_thumbnail

Future<Uint8List?> generateThumbnail(File file) async {
    final thumbnail = await VideoThumbnail.thumbnailData(
      video: file.path,
      imageFormat: ImageFormat.JPEG,
      maxHeight: 80,
      maxWidth: 80,
      quality: 5,
    );
    return thumbnail;
  }
