CodePudding user response：

You would have to retrive data from firebase and then display it.

Example:

class ProfilePage extends StatefulWidget {
  const ProfilePage({super.key});

  @override
  State<ProfilePage> createState() => _ProfilePageState();
}

class _ProfilePageState extends State<ProfilePage> {
  String? name;

  @override
  void initState() {
    FirebaseFirestore.instance
        .collection('Users')
        .doc(FirebaseAuth.instance.currentUser!.uid) //
