Flutter实现视频播放功能

1.引入库。

video_player: ^0.10.0&＃43;2

import &＃39;package:flutter/cupertino.dart&＃39;;
import &＃39;package:flutter/material.dart&＃39;;
import &＃39;package:video_player/video_player.dart&＃39;;void main() &＃61;> runApp(showVideo());class showVideo extends StatefulWidget {&＃64;overrideState createState() {// TODO: implement createStatereturn new _VideoAppState();}
}class _VideoAppState extends State {VideoPlayerController _controller;&＃64;overridevoid initState() {super.initState();_controller &＃61; VideoPlayerController.network(&＃39;http://192.168.19.233/topwayims/files/1564539968501_video.mp4&＃39;)..initialize().then((_) {setState(() {});});}&＃64;overrideWidget build(BuildContext context) {return MaterialApp(title: &＃39;Video Demo&＃39;,home: Scaffold(body: Center(child: _controller.value.initialized? AspectRatio(aspectRatio: _controller.value.aspectRatio,child: VideoPlayer(_controller),): Container(),),floatingActionButton: FloatingActionButton(onPressed: () {setState(() {_controller.value.isPlaying? _controller.pause(): _controller.play();});},child: Icon(_controller.value.isPlaying ? Icons.pause : Icons.play_arrow,),),),);}&＃64;overridevoid dispose() {super.dispose();_controller.dispose();}
}
