未处理的异常:类型'String'不是类型'List< String>'的子类型

我正在尝试共享一个包含视频的文件，但出现错误提示

Im trying to share a file which includes a video but im getting an error that says

[VERBOSE-2:ui_dart_state.cc(186)] Unhandled Exception: type 'String' is not a subtype of type 'List<String>'
#0      _VideopageofcurrentuserState.sharevideo (package:wichtigdenyady/taking%20videos/currentuservideos.dart:90:17)
<asynchronous suspension>

这是我的代码

 InkWell(
                                          onTap: () => sharevideo(
                                              videos.data()['videourl'],
                                              videos.data()['id']),
                                          child: Icon(Icons.reply,
                                              size: 35, color: Colors.white),
                                        ),

因此，我给共享视频功能提供了视频的网址以及视频文档的ID，然后就给了我共享视频功能

So im giving the share video function the url of the video and also the id of the document of the video and then thats my share video function

  sharevideo(String video, String id) async {
    DocumentSnapshot doc =
        await FirebaseFirestore.instance.collection('videos').doc(id).get();
    var request = await HttpClient().getUrl(Uri.parse(video));
    var response = await request.close();
    Uint8List bytes = await consolidateHttpClientResponseBytes(response);
    await Share.shareFiles(
      doc.data()['videourl'],
      text: 'Video.mp4',
    ).whenComplete(() => FirebaseFirestore.instance
        .collection('videos')
        .doc(id)
        .update({'sharecount': doc.data()['sharecount'] + 1}));
  }
