Flutter: video player crop/cover - flutter

Question

I'm trying to show a video inside a container, videos could exceed container's aspect ratio, so the they need to be cropped.
With images it is simple as that:
Image.network(someUrl, fit: BoxFit.cover)
but how to do it with VideoPlayer?
my current code looks like this:
Stack(
children: [
Container(
width: double.infinity,
height: double.infinity,
child: ShowcaseVideoPlayer(someUrl)
),
Material(
color: Colors.transparent,
child: InkWell(
onTap: () {},
),
),
],);
class ShowcaseVideoPlayer extends StatefulWidget {
final String url;
ShowcaseVideoPlayer(this.url);
#override
_ShowcaseVideoPlayerState createState() => _ShowcaseVideoPlayerState();
}
class _ShowcaseVideoPlayerState extends State<ShowcaseVideoPlayer> {
VideoPlayerController _controller;
Future<void> _initializeVideoPlayerFuture;
#override
void initState() {
_controller = VideoPlayerController.network(widget.url);
_initializeVideoPlayerFuture = _controller.initialize();
_controller.setVolume(0);
super.initState();
}
#override
Widget build(BuildContext context) {
return FutureBuilder(
future: _initializeVideoPlayerFuture,
builder: (context, snapshot) {
if (snapshot.connectionState == ConnectionState.done) {
_controller.play();
// If the VideoPlayerController has finished initialization, use
// the data it provides to limit the aspect ratio of the VideoPlayer.
return AspectRatio(
aspectRatio: _controller.value.aspectRatio,
// Use the VideoPlayer widget to display the video.
child: VideoPlayer(_controller),
);
} else {
// If the VideoPlayerController is still initializing, show a
// loading spinner.
return Center(),
);
}
},
);
}
#override
void dispose() {
_controller.dispose();
super.dispose();
}
}
I need a stack as I will have to show other things over the video. I tried without the stack and the player maintains the aspect ratio of the video, basically letter-boxing it. With the stack, the video stratches, losing the original aspect ratio:
to be clear, what I want is this:
EDIT: I tried random things on it and managed to achieve something, I removed the Container and wrapped the VideoPlayer like this:
Stack(
children: [
OverflowBox(
child: Wrap(
children: [
ShowcaseVideoPlayer(someUrl)
],
),
)]);
now the the video is actually cropped, but not centered (I see the upper part of the video instead of the central one). Wrapping Wrap in a Center and setting alignment: Alignment.center on OverfowBox have no effect. Any idea?
