dependencies:
  firebase_core: ^1.10.0
  firebase_auth: ^3.3.0
  cloud_firestore: ^3.1.0

import 'package:firebase_core/firebase_core.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp();
  runApp(MyApp());
}

import 'package:cloud_firestore/cloud_firestore.dart';

final FirebaseFirestore firestore = FirebaseFirestore.instance;

Future<String> getDataFromFirebase() async {
  try {
    DocumentSnapshot documentSnapshot =
        await firestore.collection('your_collection').doc('your_document_id').get();
    Map<String, dynamic> data = documentSnapshot.data() as Map<String, dynamic>;
    String value = data['your_field_name'];
    return value;
  } catch (e) {
    print('Error retrieving data from Firebase: $e');
    return '';
  }
}

String firebaseValue = await getDataFromFirebase();

Text(firebaseValue),
