如何在Flutter中创建垂直tabBar？

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

@override
Widget build(BuildContext context) {
  return DefaultTabController(
    length: 3, // 选项卡的数量
    child: Scaffold(
      appBar: AppBar(
        title: Text('垂直TabBar示例'),
      ),
      body: Column(
        children: [
          TabBar(
            isScrollable: true, // 设置为可滚动
            tabs: [
              Tab(text: '选项卡1'),
              Tab(text: '选项卡2'),
              Tab(text: '选项卡3'),
            ],
          ),
          Expanded(
            child: TabBarView(
              children: [
                // 每个选项卡的内容
                Center(child: Text('选项卡1的内容')),
                Center(child: Text('选项卡2的内容')),
                Center(child: Text('选项卡3的内容')),
              ],
            ),
          ),
        ],
      ),
    ),
  );
}
