使用flutter在firestore上执行CRUD操作的最佳方式是什么？

dependencies:
  cloud_firestore: ^2.5.4

import 'package:cloud_firestore/cloud_firestore.dart';

FirebaseFirestore firestore = FirebaseFirestore.instance;

void createDocument() {
  firestore.collection('collectionName').doc('documentId').set({
    'field1': 'value1',
    'field2': 'value2',
  });
}

void readDocument() {
  firestore.collection('collectionName').doc('documentId').get().then((DocumentSnapshot documentSnapshot) {
    if (documentSnapshot.exists) {
      print('Document data: ${documentSnapshot.data()}');
    } else {
      print('Document does not exist');
    }
  });
}

void updateDocument() {
  firestore.collection('collectionName').doc('documentId').update({
    'field1': 'updatedValue1',
    'field2': 'updatedValue2',
  });
}

void deleteDocument() {
  firestore.collection('collectionName').doc('documentId').delete();
}
