视频播放器颤振的基本界面

【中文标题】视频播放器颤振的基本界面

【英文标题】：Basic interface for video player flutter

【发布时间】：2020-12-04 03:47:03

【问题描述】：

我正在使用这个库来实现视频功能。

https://pub.dev/packages/video_player

目前，我已经成功地让它工作了。

但是，接下来，我需要通过代码制作播放/暂停或搜索按钮？？

我想要的只是简单的控制器，比如OS基本播放器，没有可设计的就可以了。

我想有一种方法可以更轻松地实现接口，而无需重新发明***......

我说的对吗？

我四处搜索，但找不到。

【参考方案1】：

你可以使用包https://pub.dev/packages/chewie video_player 插件提供对视频播放的低级访问。 Chewie 在引擎盖下使用 video_player 并将其包裹在友好的 Material 或 Cupertino UI 中！

示例代码的工作演示

示例代码https://github.com/brianegan/chewie/tree/master/example

import 'package:chewie/chewie.dart';
import 'package:chewie/src/chewie_player.dart';
import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';
import 'package:video_player/video_player.dart';

void main() 
  runApp(
    ChewieDemo(),
  );


class ChewieDemo extends StatefulWidget 
  ChewieDemo(this.title = 'Chewie Demo');

  final String title;

  @override
  State<StatefulWidget> createState() 
    return _ChewieDemoState();
  


class _ChewieDemoState extends State<ChewieDemo> 
  TargetPlatform _platform;
  VideoPlayerController _videoPlayerController1;
  VideoPlayerController _videoPlayerController2;
  ChewieController _chewieController;

  @override
  void initState() 
    super.initState();
    _videoPlayerController1 = VideoPlayerController.network(
        'https://flutter.github.io/assets-for-api-docs/assets/videos/butterfly.mp4');
    _videoPlayerController2 = VideoPlayerController.network(
        'https://www.sample-videos.com/video123/mp4/480/asdasdas.mp4');
    _chewieController = ChewieController(
      videoPlayerController: _videoPlayerController1,
      aspectRatio: 3 / 2,
      autoPlay: true,
      looping: true,
      // Try playing around with some of these other options:

      // showControls: false,
      // materialProgressColors: ChewieProgressColors(
      //   playedColor: Colors.red,
      //   handleColor: Colors.blue,
      //   backgroundColor: Colors.grey,
      //   bufferedColor: Colors.lightGreen,
