为什么 VideoPlayer 中的视频不是全屏的？

Question

我复制粘贴了VideoPlayer package的例子，但是网页上不是全屏，请问如何解决。

示例代码

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

class HomeScreen extends StatefulWidget {
  const HomeScreen({Key? key}) : super(key: key);
  @override
  _HomeScreenState createState() => _HomeScreenState();
}

class _HomeScreenState extends State<HomeScreen> {
  late VideoPlayerController _controller;

  @override
  void initState() {
    super.initState();
    _controller = VideoPlayerController.network(
        'https://assets.mixkit.co/videos/preview/mixkit-womans-hands-decorating-a-handmade-soap-2803-large.mp4')
      ..initialize().then((_) {
        // Ensure the first frame is shown after the video is initialized, even before the play button has been pressed.
        setState(() {});
      })
      ..play()
      ..setLooping(true);
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Video Demo',
      home: Scaffold(
        body: _controller.value.isInitialized
            ? AspectRatio(
                aspectRatio: _controller.value.aspectRatio,
                child: VideoPlayer(_controller),
              )
            : Container(),
      ),
    );
  }

  @override
  void dispose() {
    super.dispose();
    _controller.dispose();
  }
}

Answer 1

如果您勾选 _controller.value.aspectRatio,，value 来自视频。

视频根据其 aspectRatio 而非屏幕的纵横比播放。

我用LayoutBuilder获取屏幕尺寸，你也用MediaQuery。在这种情况下 homme: 就像

 home: Scaffold(
        body: LayoutBuilder(
          builder: (context, constraints) => _controller.value.isInitialized
              ? AspectRatio(
                  aspectRatio: constraints.maxWidth / constraints.maxHeight,
                  // _controller.value.aspectRatio,
                  child: VideoPlayer(_controller),
                )
              : Container(),
        ),
      ),

结果

is you are thinking about Top and bottom spaces here, is empty because of it is beyond video aspectRatio.

我为此使用了堆栈，它非常适合我。基于此视频：
