写一个flutter实例,有视频地址列表和频道列表,使用fijkplayer插件来播放flv视频,点击不同频道切换不同视频地址,一开始就是全屏播放

好的，以下是一个简单的 Flutter 实例，使用 fijkplayer 插件来播放 FLV 视频，并且可以切换不同的视频地址：

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

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Fijkplayer Demo',
      home: MyHomePage(),
    );
  }
}

class MyHomePage extends StatefulWidget {
  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  final FijkPlayer player = FijkPlayer();

  List<String> channelList = [
    'https://example.com/video1.flv',
    'https://example.com/video2.flv',
    'https://example.com/video3.flv',
  ];

  int currentChannelIndex = 0;

  @override
  void initState() {
    super.initState();
    player.setDataSource(channelList[currentChannelIndex], autoPlay: true);
  }

  @override
  void dispose() {
    player.release();
    super.dispose();
  }

  void switchChannel(int index) {
    setState(() {
      currentChannelIndex = index;
    });
    player.reset();
    player.setDataSource(channelList[currentChannelIndex], autoPlay: true);
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Flutter Fijkplayer Demo'),
      ),
      body: Column(
        children: [
          Expanded(
            child: FijkView(
              player: player,
              fit: FijkFit.cover,
            ),
          ),
          Container(
            height: 50,
            child: ListView.builder(
              scrollDirection: Axis.horizontal,
              itemCount: channelList.length,
              itemBuilder: (context, index) {
                return GestureDetector(
                  onTap: () => switchChannel(index),
                  child: Container(
                    padding: EdgeInsets.symmetric(horizontal: 16),
                    alignment: Alignment.center,
                    color: currentChannelIndex == index
                        ? Colors.blue
                        : Colors.grey,
                    child: Text(
                      'Channel ${index + 1}',
                      style: TextStyle(
                        color: Colors.white,
                        fontWeight: FontWeight.bold,
                      ),
                    ),
                  ),
                );
              },
            ),
          ),
        ],
      ),
    );
  }
}

在这个例子中，我们使用了 `FijkPlayer` 来播放 FLV 视频，并且使用了 `FijkView` 来显示视频。我们还使用了一个 `ListView` 来显示频道列表，并且可以点击不同的频道来切换视频地址。
