// Flutter视频列表页
class VideoListPage extends StatefulWidget {
  @override
  _VideoListPageState createState() => _VideoListPageState();
}

class _VideoListPageState extends State<VideoListPage> {
  final ScrollController _scrollController = ScrollController();
  List<Video> _videos = [];
  bool _isLoading = false;
  int _page = 1;

  @override
  void initState() {
    super.initState();
    _loadVideos();
    _scrollController.addListener(_scrollListener);
  }

  Future<void> _loadVideos() async {
    if (_isLoading) return;
    
    setState(() => _isLoading = true);
    final response = await http.get('$API_URL/videos?page=$_page');
    final newVideos = videoFromJson(response.body);
    
    setState(() {
      _videos.addAll(newVideos);
      _page++;
      _isLoading = false;
    });
  }

  void _scrollListener() {
    if (_scrollController.position.pixels == 
        _scrollController.position.maxScrollExtent) {
      _loadVideos();
    }
  }

  @override
  Widget build(BuildContext context) {
    return ListView.builder(
      controller: _scrollController,
      itemCount: _videos.length + 1,
      itemBuilder: (context, index) {
        if (index == _videos.length) {
          return _buildLoader();
        }
        return VideoCard(video: _videos[index]);
      },
    );
  }
}

思路讲解：

1. Flutter实现高性能跨平台移动应用

2. Django提供强大的后台管理和API支持

3. 实现分页加载和无限滚动

4. 使用Django REST framework构建标准化API

5. 可轻松扩展后台管理功能
