looking at the difference in code it looks like a permission error, i am not sure but it may lead you to a fix 4083ae4

since the checks for permission got removed

problem:file_picker: ^8.1.6
1.only support video and images ,others return null
demo code:
`
PermissionStatus status = await Permission.photos.request();
LogE("PermissionStatus.photos:${status.isGranted}"); // true
status = await Permission.videos.request();
LogE("PermissionStatus.videos:${status.isGranted}"); // true
status = await Permission.audio.request();
LogE("PermissionStatus.audio:${status.isGranted}"); // true
status = await Permission.manageExternalStorage.request();
LogE("PermissionStatus.manageExternalStorage:${status.isGranted}"); // true

FilePickerResult? result = await FilePicker.platform.pickFiles(
  allowCompression: false,
  allowMultiple: true,
  type: FileType.video,//  FileType.image, FileType.audio
);

2.[allowedExtensions] 2.1.works well code:
type: FileType.custom,
allowedExtensions: ['jpg', 'png', 'mp4', 'mov'],
2.2.return null
type: FileType.custom,// FileType.any
allowedExtensions: ['pdf','docx'],
`
2.3.console log:return null
[ ] I/FilePickerDelegate(20648): User cancelled the picker request

3.file_picker: ^8.1.4

always works well
