Flutter-实现视频播放功能

1.引入库。

video_player: ^0.10.0+2

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

void main() => runApp(showVideo());

class showVideo extends StatefulWidget {
  @override
  State createState() {
    // TODO: implement createState
    return new _VideoAppState();
  }
}

class _VideoAppState extends State {
  VideoPlayerController _controller;

  @override
  void initState() {
    super.initState();
    _controller = VideoPlayerController.network('http://192.168.19.233/topwayims/files/1564539968501_video.mp4')
      ..initialize().then((_) {
        setState(() {});
      });
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Video Demo',
      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,
          ),
        ),
      ),
    );
  }

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