StreamBuilder(
       stream: Firestore.instance.collection("/userdata").snapshots(),
       builder: (context, snapshot) {
     gnickname = snapshot.data.documents[0]["Nickname"];
     gphotourl = snapshot.data.documents[0]["photoURL"];})

You are trying to get all the records in the userdata collection right, but you are only getting the first one? — unbalanced_equation

To get a specific record based on the uid use, in your case, the following code:

var userData = Firestore.instance.collection("/userdata").document("uid").get();

userData is a DocumentSnapshot so use userData.data object to get the key/value pairs.

You can do it like that for first collection

   StreamBuilder(
           stream: Firestore.instance.collection("/userdata").snapshots(),
           builder: (context, snapshot) {
         gnickname = snapshot.data.documents.first["Nickname"];
         gphotourl = snapshot.data.documents.first["photoURL"];})

To get specific user you can try:

Firestore.instance.collection('your_collection').document('your_id').snapshots()
