如何在 flutter 中显示来自 Firestore 的特定文档详细信息

Question

I am trying to fetch a single document from firestore against the current logged in user. I need that piece of code if anyone can provide it.

As writtenn in the cloud firestore docs this is how you can fetch a single document:

Firestore.instance
        .collection("users")
        .document(userId)
        .get()
        .then((DocumentSnapshot ds) {
      // use ds as a snapshot
    });

If you have the user id you can use it as the document name to load a specific document per user.
