Firestore:如何使用Dart将一个集合的多个子集合写入firestore

dependencies:
  cloud_firestore: ^2.5.3

import 'package:cloud_firestore/cloud_firestore.dart';

FirebaseFirestore firestore = FirebaseFirestore.instance;

void writeSubcollections() {
  // 创建一个集合
  CollectionReference collection = firestore.collection('my_collection');

  // 创建多个子集合
  Map<String, dynamic> subcollection1 = {
    'name': 'Subcollection 1',
    'description': 'This is subcollection 1'
  };

  Map<String, dynamic> subcollection2 = {
    'name': 'Subcollection 2',
    'description': 'This is subcollection 2'
  };

  // 写入子集合
  collection.doc('document_id').collection('subcollections').add(subcollection1);
  collection.doc('document_id').collection('subcollections').add(subcollection2);
}
