iOS crash when file name has empty space.

I have attached the code and log of exceptions thrown when I tried to initialize a player with an empty name in iOS. Is there a workaround for this issue if anyone has encountered it before?

```
Future initializePlayer() async {
_videoPlayerController1 =
VideoPlayerController.asset('assets/video 1.mp4');
_videoPlayerController2 =
VideoPlayerController.asset('assets/video 1.mp4');
await Future.wait([
_videoPlayerController1.initialize(),
_videoPlayerController2.initialize()
]);
_createChewieController();
setState(() {});
}
```

**Error**

```
