以下是视频列表的示例。

  ),
  body: StreamBuilder<QuerySnapshot>(
    stream: FirebaseFirestore.instance.collection('videos').snapshots(),
    builder: (context, snapshot) {
      if (!snapshot.hasData) {
        return CircularProgressIndicator();
      }
      final videoList = snapshot.data.docs;

      return ListView.builder(
        itemCount: videoList.length,
        itemBuilder: (context, index) {
          final videoData = videoList[index];
          final videoUrl = videoData['video_url'];

          return ListTile(
            title: Text(videoData['title']),
            onTap: () {
              // Play the list of videos
              Navigator.push(
