如何在使用get作为状态管理组件时初始化TabController

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

class MyPage extends StatefulWidget {
  @override
  _MyPageState createState() => _MyPageState();
}

class _MyPageState extends State<MyPage> with SingleTickerProviderStateMixin {
  TabController _tabController;

  @override
  void initState() {
    super.initState();
    _tabController = TabController(length: 2, vsync: this);
  }

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

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('My Page'),
        bottom: TabBar(
          controller: _tabController,
          tabs: [
            Tab(text: 'Tab 1'),
            Tab(text: 'Tab 2'),
          ],
        ),
      ),
      body: TabBarView(
        controller: _tabController,
        children: [
          // Tab 1 content
          Container(),
          // Tab 2 content
          Container(),
        ],
      ),
    );
  }
}
