videoPlayer 공부 중입니다. aspectRatio 실행 시 동영상 위치가 가운데로 정렬되지 않고 상단에 배치가 됩니다.

아래와 같이 동영상 보고 따라 하였는데 원인이 무엇일까요?

import 'dart:io';

import 'package:flutter/material.dart';
import 'package:image_picker/image_picker.dart';
import 'package:video_player/video_player.dart';

class CustomVideoPlayer extends StatefulWidget {
  final XFile video;

  const CustomVideoPlayer({required this.video, Key? key}) : super(key: key);

  @override
  State<CustomVideoPlayer> createState() => _CustomVideoPlayerState();
}

class _CustomVideoPlayerState extends State<CustomVideoPlayer> {
  VideoPlayerController? videoPlayerController;

  @override
  void initState() {
    // TODO: implement initState
    super.initState();
    initialController();
  }

  initialController() async {
    videoPlayerController = VideoPlayerController.file(File(widget.video.path));
    await videoPlayerController!.initialize();
    setState(() {});
  }

  @override
  Widget build(BuildContext context) {
    if (videoPlayerController == null) {
      return CircularProgressIndicator();
    }
    return AspectRatio(
        aspectRatio: videoPlayerController!.value.aspectRatio,
        child: VideoPlayer(videoPlayerController!));
  }
}
