显示所有用户数据，想在我的个人资料部分显示刚刚记录的用户数据
Showing all user data, Want to show just logged user data in my profile section
我想在 crrentUser/loggedIn 用户数据中显示我的个人资料 Drawer 当我滑动它时，将显示 current/login 用户 'name, email, photos' 还会有其他一些东西，例如注销按钮等。但是当我登录时该用户仪表板中的任何用户。当我 click/slide 在我的抽屉上时，它显示了我存储在 Firestore 中 用户集合 下的所有用户数据。我只想显示 Current 用户个人资料数据，如姓名电子邮件等。但它显示了来自 Firestore[ 的所有 collection =34=]。目前，我在我的 firebase 中的 users 集合中有 3 个用户。问题是当我 slide/click 抽屉时，它在我的 抽屉 中显示所有 3users 数据。但我只想在 Drawer
中显示 current/login 用户数据

所以我认为问题出在我假设的 steamBuider 上。我认为 SteamBuilder 打印 集合 中的所有内容。因为我只需要使用 SreamBuilder 打印我的 current/login 用户，所以它从 users 集合，这就是问题发生的原因。
现在我更改为 FutureBuilder 并且现在可以正常工作了。
**我不确定 StreamBuilder 有什么问题，但如果我需要整个集合，那么我将使用 SteamBuilder 否则，如果我只需要Collection 下的特定 document 然后我将使用 FutureBuilder.
这是我的意见，如果有人能提供一些非常有帮助的想法
