使用shrinkWrap/SizedBox/Expanded仍未解决Flutter RenderFlex错误

构建用于展示菜品评价的AlertDialog时出现以下错误：

The following assertion was thrown during performLayout():
RenderShrinkWrappingViewport does not support returning intrinsic dimensions. Updated layout information required for RenderFlex#d31e4 relayoutBoundary=up7 NEEDS-LAYOUT NEEDS-PAINT to calculate semantics.
'package:flutter/src/rendering/object.dart': Failed assertion: line 3175 pos 12: '!_needsLayout'

使用的AlertDialog代码：

return AlertDialog(
title: Center(child: Text("Αξιολογήσεις")),
content: Column(
  mainAxisSize: MainAxisSize.min,
  children: [
      Divider(height: 5, color: Colors.blueGrey,),
      StreamBuilder<List<Review>>(
        stream: DatabaseService(collectionName: 'ratings').reviews,
        builder: (context, snapshot) {
          if (!snapshot.hasData) {
            return CircularProgressIndicator();
          }
          final reviews = snapshot.data!;
          return ListView(
            shrinkWrap: true,
            children: reviews.map((review) => Review(rating: review.rating, username: review.timestamp, review: review.review, timestamp: review.timestamp,)).toList(),
          );
        },
      ),
  ],
),
);

Review组件代码：

class Review extends StatelessWidget{
  final String username;
  final double rating;
  final String review;
  final String timestamp;
  const Review({super.key, required this.rating, required this.username, required this.review, required this.timestamp});

  @override
  Widget build(BuildContext context){
    return ListTile(
        title: Column(
          mainAxisSize: MainAxisSize.min,
          children: [
            Row(mainAxisSize: MainAxisSize.min, children: <Widget>[
              CircleAvatar(
                backgroundImage: AssetImage('assets/logo_circle_white.png'),
                radius: 24.0,
              ),
              SizedBox(width: 8,),
              Expanded(child: Text("Ο χρήστης $username αναφέρει:",style: TextStyle(fontSize: 16, fontStyle: FontStyle.italic),))
            ]),
          ],
        ),
      subtitle: Column(
        children: [
          Text('Η κριτική υποβλήθηκε στις: $timestamp'),
          Divider()
        ],
      ),
      trailing: Text('$rating'),
    );
  }
}

数据库函数代码：

//get item stream
  Stream<List<Review>> get reviews{
    return itemCollection.snapshots().map(_getRatingsFromSnapshot);
  }

  List<Review> _getRatingsFromSnapshot(QuerySnapshot snapshot){ // _ makes it private
    try {
      return snapshot.docs.map((doc) { // map cycles through document list
        return Review( //return a review for each one
          username: doc.get('username') ?? 'anonymous',
          rating: doc.get('rating').toDouble() ?? 0.0,
          review: doc.get('review') ?? '-',
          timestamp: doc.get('timestamp') ?? '00:00 00/00/00',
        );
      }).toList(); // convert iterable to list
    }
    catch(e){
      print(e.toString());
      return [];
    }
  }

已尝试将ListView放入Expanded、指定高度的SizedBox，用SingleChildScrollView包裹ListView或StreamBuilder，但均未解决问题。

错误核心是AlertDialog的content布局约束与shrinkWrap: true的ListView存在计算冲突，加上StreamBuilder动态更新数据时触发了布局断言。以下是修复步骤：

1. 用SingleChildScrollView包裹整个content区域的Column，让AlertDialog内容可整体滚动，避免内容溢出
2. 给ListView添加physics: NeverScrollableScrollPhysics()，禁用自身滚动（外层已有滚动容器，避免嵌套滚动导致布局混乱）
3. 修正Review组件的传参笔误：之前将review.timestamp传给了username，需改为review.username

修改后的AlertDialog代码：

return AlertDialog(
  title: const Center(child: Text("Αξιολογήσεις")),
  content: SingleChildScrollView(
    padding: EdgeInsets.zero,
    child: Column(
      mainAxisSize: MainAxisSize.min,
      children: [
        const Divider(height: 5, color: Colors.blueGrey),
        StreamBuilder<List<Review>>(
          stream: DatabaseService(collectionName: 'ratings').reviews,
          builder: (context, snapshot) {
            if (!snapshot.hasData) {
              return const CircularProgressIndicator();
            }
            final reviews = snapshot.data!;
            return ListView(
              shrinkWrap: true,
              physics: const NeverScrollableScrollPhysics(),
              children: reviews.map((review) => Review(
                rating: review.rating,
                username: review.username,
                review: review.review,
                timestamp: review.timestamp,
              )).toList(),
            );
          },
        ),
      ],
    ),
  ),
);
