如何将不同的数据类型添加到flutter中的firestore

dependencies:
  flutter:
    sdk: flutter
  cloud_firestore: ^2.5.3

import 'package:firebase_core/firebase_core.dart';
import 'package:cloud_firestore/cloud_firestore.dart';

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

import 'package:cloud_firestore/cloud_firestore.dart';

// 获取集合的引用
CollectionReference users = FirebaseFirestore.instance.collection('users');

// 添加文档到集合
Future<void> addUser() {
  return users
      .add({
        'name': 'John Doe',
        'age': 30,
        'isMarried': false,
        'hobbies': ['reading', 'traveling'],
        'address': {
          'street': '123 Main St',
          'city': 'New York',
        },
      })
      .then((value) => print('User added'))
      .catchError((error) => print('Failed to add user: $error'));
}

import 'package:cloud_firestore/cloud_firestore.dart';

// 获取集合的引用
CollectionReference users = FirebaseFirestore.instance.collection('users');

// 获取集合中的所有文档
Future<void> getUsers() {
  return users.get().then((QuerySnapshot querySnapshot) {
    querySnapshot.docs.forEach((doc) {
      print(doc.data());
    });
  });
}
