无法在 VideoPlayer 中从服务器 url 播放视频：Flutter

Question

我无法使用颤振的视频播放器库从我的服务器播放视频当我尝试flutter视频工作正常并播放时，但如果我播放我的服务器端url视频，则会显示错误和黑屏。所以请帮助我缩短这个查询。

代码是

import 'package:audioplayers/audioplayers.dart';
import 'package:flutter/material.dart';
import 'package:video_player/video_player.dart';
class MyVideoPlayerPage extends StatefulWidget {
  String myvideo;
  MyVideoPlayerPage({this.myvideo});
  @override
  _MyVideoPlayerPageState createState() => _MyVideoPlayerPageState(myvideo);
}

class _MyVideoPlayerPageState extends State<MyVideoPlayerPage> {
  String myvideo;
  _MyVideoPlayerPageState(this.myvideo);
  VideoPlayerController _controller;
  Future<void> _initializeVideoPlayerFuture;



  @override
  void initState() {
    // TODO: implement initState
    super.initState();
    _controller = VideoPlayerController.network(
      //'http://ochapchap.com/public/propertyImage/1594746367.VID-20200713-WA0001.mp4'
    // 'http://techslides.com/demos/sample-videos/small.mp4',
      'https://flutter.github.io/assets-for-api-docs/assets/videos/butterfly.mp4'
    );
    _initializeVideoPlayerFuture = _controller.initialize();
    _controller.setLooping(true);
    _controller.setVolume(1);
  }
  @override
  void dispose() {
    _controller.dispose();

    super.dispose();
  }
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text("Video"),
      ),
      body: FutureBuilder(
        future: _initializeVideoPlayerFuture,
        builder: (context, snapshot) {
          if (snapshot.connectionState == ConnectionState.done) {
            // not wrapped in an AspectRatio widget
            return VideoPlayer(_controller);
          } else {
            return Center(child: CircularProgressIndicator());
          }
        },
      ),
      floatingActionButton: FloatingActionButton(
        onPressed: () {
          print(myvideo);
          setState(() {
            if (_controller.value.isPlaying) {
              _controller.pause();
            } else {
              _controller.play();
            }
          });
        },
        child: Icon(
          _controller.value.isPlaying ? Icons.pause : Icons.play_arrow,
        ),
      ),
    );
  }
}

但是当我把这个颤振开发视频播放时，就像魅力一样。链接是https://flutter.github.io/assets-for-api-docs/assets/videos/butterfly.mp4 ，我的服务器链接不播放是http://ochapchap.com/public/propertyImage/1594746367.VID-20200713-WA0001.mp4

我的链接上显示的错误是

Answer 1

这个地址使用http，如果这个链接支持https，可以直接使用https
to use withhttp和
to deal withCleartext HTTP traffic to site not permitted
可以编辑android\app\src\main\AndroidManifest.xml添加android:usesCleartextTraffic="true"

代码片段

 <application
        android:name="yourName"
        android:label="yourLable"
        android:usesCleartextTraffic="true"
