How to get current user data like name and email from firebase realtime databse for one user to Text Field in flutter?

Question

I'm new to flutter and I'm trying to create a profile screen to get user data from firebase's real-time database like name, email, and phone number. I tried to search on google but all the examples I found are to get data from the Firestore database, not the real-time database. I would appreciate it if somebody helps me.

You need to do something like this:

    Future<String> getUsername() async {
    final ref = FirebaseDatabase.instance.reference();
    User cuser = await firebaseAuth.currentUser;

    return ref.child('User_data').child(cuser.uid).once().then((DataSnapshot snap) {
      final String userName = snap.value['name'].toString();
      print(userName);
      return userName;
    });
  }
