如何在Flutter MacOS中禁用拖动滚动但保持鼠标滚轮滚动ListView？

在Flutter中，如果你想在MacOS上禁用拖动滚动但保持鼠标滚轮滚动ListView，你可以通过自定义GestureDetector来实现。以下是一个简单的示例代码，展示了如何实现这一功能：

import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(title: Text('Disable Drag Scroll')),
        body: MyListView(),
      ),
    );
  }
}

class MyListView extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return GestureDetector(
      onPanStart: (_) {
        // Disable drag scrolling by returning false
        return false;
      },
      child: ListView.builder(
        itemCount: 100,
        itemBuilder: (context, index) {
          return ListTile(title: Text('Item $index'));
        },
      ),
    );
  }
}
