Chewie return PlayerWithControls in build, but in PlayerWithControls,
I found it returns a SizedBox with screen height and screen width
i want to change the size to wrap with the video player, how to change the size of it?

```
return Center(
child: SizedBox(
height: MediaQuery.of(context).size.height,
width: MediaQuery.of(context).size.width,
child: AspectRatio(
aspectRatio: calculateAspectRatio(context),
child: buildPlayerWithControls(chewieController, context),
),
),
);
```
