我的应用程序在提交评论后不断崩溃。我相信当Firebase去检索评论数据以显示它时，崩溃就会发生。这仅在尝试提交评论时发生。当我发布照片或喜欢任何帖子时，它不会发生。所以我无法弄清楚为什么我在那里只有一个 Firestore 问题。
这是我的颤振配置：

这是保存注释的函数：
saveComment(){
commentsReference.document(postId).collection("comments").add({
"username": currentUser.username,
"comment": commentTextEditingController.text,
"timestamp": DateTime.now(),
"url": currentUser.url,
"userId": currentUser.id,
});
bool isNotPostOwner = postOwnerId != currentUser.id;
if(isNotPostOwner) {
activityFeedReference.document(postOwnerId).collection("feedItems").add({
"type": "comment",
"commentDate": timestamp,
"postId": postId,
"userId": currentUser.id,
"username": currentUser.username,
"userProfileImg": currentUser.url,
"url": postImageUrl,
});
}
commentTextEditingController.clear();
}
有人可以帮我解决这个问题吗？
我想通了。这完全是我的错。 我有
CommentsPageState createState() => CommentsPageState(postId: postId, postOwnerId: postImageUrl, postImageUrl: postImageUrl);
而不是
CommentsPageState createState() => CommentsPageState(postId: postId, postOwnerId: postOwnerId, postImageUrl: postImageUrl);
所以它正在获取postImageUrl链接而不是postOwnerId
