get user data from uid in firebase database flutter

You should call Firestore method get()
to fetch data, then read the returned document from the callback.
FirebaseDatabase.instance.reference().child('user').child(uid).get().then((docSnapshot) {
print(docSnapshot.data()["email"]); // print data to test
});

Can you help me? I've only been learning Flutter for a few months and I want to get user data from Firebase and display the user profile. But it doesn't work, this is my code:
DatabaseReference _ref; var email, nama, noTelp; @override void initState() { // TODO: implement initState super.initState(); final User usernya = _auth.currentUser; final String uid = usernya.uid; _ref = FirebaseDatabase.instance.reference().child('user').child(uid); email = _ref.child('email'); nama = _ref.child('nama'); noTelp = _ref.child('noTelp'); }
And this code for user profiles:
Column( crossAxisAlignment: CrossAxisAlignment.start, children: [ _ref == null ? Text( 'Nama Pengguna', style: TextStyle( fontSize: 18, fontWeight: FontWeight.bold, color: Colors.white), ) : Text( nama.toString(), style: TextStyle( fontSize: 18, fontWeight: FontWeight.bold, color: Colors.white), ), Text( email.toString(), style: (TextStyle(color: Colors.white)), ), Text(noTelp.toString(), style: (TextStyle(color: Colors.white))) ], )
And I get output like this instance of 'Database Reference'
This is my user data in firebase:
And I got output like this:
