Flutter - 将背景渐变应用于可 ScrollView

Question

有没有办法在 Flutter 中将完整的背景渐变应用于可 ScrollView (例如 ListView 或 SingleChildScrollView)？我尝试了各种方法，例如将渐变应用于 Scaffold 或将 Scaffold 包装在 Container 中，但渐变似乎只是随内容滚动，而不是应用于完整的可滚动高度。

示例:DartPad example

import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      home: Container(
        decoration: BoxDecoration(
          gradient:LinearGradient(
            begin: Alignment.topCenter,
            end: FractionalOffset.bottomCenter,
            colors: [Colors.green, Colors.orange],
            stops: [0, 1],
          ),
        ),
        child: Scaffold(
          backgroundColor: Colors.transparent,
          body: Center(
            child: ListView.builder(
              itemCount: 500,
              itemBuilder: (_, index) => Text('$index'),
            ),
          ),
        ),
      ),
    );
  }
}

工作正常!使用 dartpad 进行测试!

如果有效，请接受答案!

import 'package:flutter/material.dart';

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

    class MyApp extends StatelessWidget {
      @override
      Widget build(BuildContext context) {
        return MaterialApp(
          debugShowCheckedModeBanner: false,
          home: Scaffold(
            body: SingleChildScrollView(
              child: Container(
                decoration: BoxDecoration(
                  gradient: LinearGradient(
                    begin: Alignment.topCenter,
                    end: FractionalOffset.bottomCenter,
                    colors: [Colors.green, Colors.orange],
                    stops: [0, 1],
                  ),
                ),
                child: Column(
                  mainAxisSize: MainAxisSize.min,
                  children: List.generate(500, (ind) {
                    return ListTile(
                      title: Text('$ind'),
                    );
                  }).toList(),
                ),
              ),
            ),
          ),
        );
      }
    }
