从flutter / firebase中的多个文档中获取项目的连接列表

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

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

Future<List<String>> getProjectConnections() async {
  List<String> connections = [];
  
  // 获取Firebase实例
  FirebaseFirestore firestore = FirebaseFirestore.instance;
  
  // 获取连接列表的集合引用
  CollectionReference connectionsRef = firestore.collection('connections');
  
  // 获取连接列表的文档快照
  QuerySnapshot snapshot = await connectionsRef.get();
  
  // 遍历文档快照，获取每个文档的连接字段值
  snapshot.docs.forEach((doc) {
    String connection = doc.data()['connection'];
    connections.add(connection);
  });
  
  return connections;
}

List<String> projectConnections = await getProjectConnections();
