如何在flutter中创建图标和文本在同一行的选项卡栏？

import 'package:flutter/material.dart';

class MyTabBar extends StatefulWidget {
  @override
  _MyTabBarState createState() => _MyTabBarState();
}

class _MyTabBarState extends State<MyTabBar> with SingleTickerProviderStateMixin {
  TabController _tabController;

  @override
  void initState() {
    super.initState();
    _tabController = TabController(length: 3, vsync: this);
  }

  @override
  void dispose() {
    _tabController.dispose();
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('TabBar Example'),
        bottom: TabBar(
          controller: _tabController,
          tabs: [
            Tab(
              icon: Icon(Icons.home),
              text: 'Home',
            ),
            Tab(
              icon: Icon(Icons.favorite),
              text: 'Favorites',
            ),
            Tab(
              icon: Icon(Icons.settings),
              text: 'Settings',
            ),
          ],
        ),
      ),
      body: TabBarView(
        controller: _tabController,
        children: [
          Center(
            child: Text('Home Content'),
          ),
          Center(
            child: Text('Favorites Content'),
          ),
          Center(
            child: Text('Settings Content'),
          ),
        ],
      ),
    );
  }
}

void main() {
  runApp(MaterialApp(
    home: MyTabBar(),
  ));
}
