在颤动/Dart中随机化/混洗Firestore流的顺序？

import 'package:flutter/material.dart';
import 'package:cloud_firestore/cloud_firestore.dart';

class RandomizedFirestoreStream extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return StreamBuilder<QuerySnapshot>(
      stream: FirebaseFirestore.instance.collection('your_collection').snapshots(),
      builder: (context, snapshot) {
        if (!snapshot.hasData) {
          return CircularProgressIndicator();
        }
        
        // 获取Firestore流中的文档列表
        final documents = snapshot.data.docs;
        
        // 将文档列表随机化/混洗
        documents.shuffle();
        
        return ListView.builder(
          itemCount: documents.length,
          itemBuilder: (context, index) {
            final document = documents[index];
            // 在这里构建你的UI
            return ListTile(
              title: Text(document['title']),
              subtitle: Text(document['subtitle']),
            );
          },
        );
      },
    );
  }
}
