如何在可滚动的小部件中包装StaggeredGridView和Row？

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

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('StaggeredGridView with Row'),
        ),
        body: SingleChildScrollView(
          child: Column(
            children: [
              StaggeredGridView.countBuilder(
                shrinkWrap: true,
                physics: NeverScrollableScrollPhysics(),
                crossAxisCount: 2,
                itemCount: 10,
                itemBuilder: (BuildContext context, int index) {
                  return Container(
                    color: Colors.blue,
                    height: 200,
                    child: Center(
                      child: Text('Item $index'),
                    ),
                  );
                },
                staggeredTileBuilder: (int index) =>
                    StaggeredTile.count(1, index.isEven ? 1.2 : 1),
                mainAxisSpacing: 8.0,
                crossAxisSpacing: 8.0,
              ),
              Row(
                children: [
                  Expanded(
                    child: Container(

                      height: 100,
                      child: Center(
                        child: Text('Row Item 1'),
                      ),
                    ),
                  ),
                  Expanded(

                      color: Colors.green,
                      height: 100,
                      child: Center(

                  ),
                ],
              ),
            ],
          ),
