Ios Flutter中抛出后期应用错误

我目前正在try 编译我的代码，但每次我都会得到相同的Latelitiation错误.这看起来是由于我的TabController造成的，但我在这里需要帮助.

我是Flutter的新手，但我知道在"迟到"之后，InitState不会启动它吗？或者我需要在小部件中的某个地方初始化TabController吗？

class _HomePageState extends State<HomePage> with SingleTickerProviderStateMixin {

  late TabController _tabController;

  @override
  void initState() {
    super.initState();
    _tabController = TabController(length: 1, vsync: this);
  }

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


  @override
  Widget build(BuildContext context) {
    return Scaffold(
      drawer: const MyDrawer(),
      body: NestedScrollView(
        headerSliverBuilder: (context, innerBoxIsScrolled) => [
          MySliverAppBar(
            title: MyTabBar(tabController: _tabController),
            child: Column(
              mainAxisAlignment: MainAxisAlignment.end,
              crossAxisAlignment: CrossAxisAlignment.start,
              children: [
                Divider(
                  indent: 25,
                  endIndent: 25,
                  color: Theme.of(context).colorScheme.secondary,
                ),
                //Add Current Location from Component
                CurrentLocation(),
                //Add Description from Component
                DescriptionBox(),
              ],
            ),
          ),
        ],
        body: 
        TabBarView(
          controller: _tabController,
          children: [
            ListView.builder(
              itemCount: 10,
              itemBuilder: (context, index) {
                return ListTile(
                  title: Text("Item $index"),
                );
              },
            ),
          ],
        ),
      ),
    );
  }
}
