我想弄清楚为什么我会收到这个错误

VERBOSE-2:ui_dart_state.cc(186)] Unhandled Exception: 'package:cloud_firestore/src/collection_reference.dart': Failed assertion: line 60 pos 14: '!path.contains('//')': a document path must not contain "//"

我要做的是：首先给方法一些数据

buildBody(videos.data()['likes'],videos.data()['videourl'])

然后在执行此操作的方法中

  Widget _buildBody( videoid,video) {
   

    return Container(
      - - - -
Stack(
                children: [
                  Padding(
                    padding: const EdgeInsets.fromLTRB(3, 7, 0, 0),
                    child: Align(
                      alignment: Alignment.topLeft,
                      child: RatingBarIndicator(
                        rating: _userRating,
                        itemBuilder: (context, index) => InkWell(
                          onTap: () {
                            setState(() {
                              _userRating = index + 1.toDouble();
                            });
                            print(index + 1.toDouble());
                            print(video);
                            likevideo(video, _userRating);
                          },
                          child: Icon(
                            Icons.star,
                            color: Colors.amber,
                          ),

所以在评分栏上点击我调用的方法就像视频一样

 likevideo(String id, double _rating) async {
    String uid = FirebaseAuth.instance.currentUser.uid;
    DocumentSnapshot doc =
        await FirebaseFirestore.instance.collection('videos').doc(id).get();
    if (!doc.data()['likes'].contains(uid)) {
      FirebaseFirestore.instance.collection('videos').doc(id).update({
        'likes': FieldValue.arrayUnion([uid]),
      });

      FirebaseFirestore.instance
          .collection('videos')
          .doc(id)
          .collection("uservotes")
          .doc(uid)
          .set({'videoid': id, 'rating': _rating, 'uid': uid});
    }
  }

这里我将用户 uid 的当前 uid 保存到数组中，并将 id、_rating 和 uid 保存到子集合中。我不知道错误是什么意思，但我认为这意味着路径所以这个值

videos.data()['videourl']

是空的，但打印时不是它给我这个

flutter: https://firebasestorage.googleapis.com/v0/b/wichtigdenyag.appspot.com/o/allvideos%2F269700204266546905SaQFz?alt=med......

那么错误从哪里开始？？？但这就是我认为也许有人知道什么是真正的错误

正如您将在 Firestore 文档中看到的那样，文档 ID 不能包含正斜杠 (/)。

因此，如果您将字符串传递https://firebasestorage.googleapis.com/v0/b/...给该doc()方法，则会返回一个错误，例如您得到的错误：a document path must not contain "//".
