Dart 在运行时动态更新TabController列表

我创建了一个Pomodoro定时器应用程序，使用flatter。主页上有日期选项卡控制器

我将用户首次使用应用程序日期记录到本地JSON文件中。当应用程序启动时，检查JSON文件并获取记录。计算今天和今天之间的天数，然后我要更新tabcontroller

结果是日期正确，我设置了初始索引设置

list.lenght-1

，但我设置了任何数字，如29,4,5,6，下划线正确，但页面视图不正确

我认为问题在于在setState中更新tabController，但我已经尝试了很多次，但都不起作用

有人能帮我看看出了什么问题吗？谢谢你的帮助

我有这样的代码，但没有工作。

void initState（）{
super.initState（）；
jsonFileHelper=新的jsonFileHelper（）；
添加（日期时间（今天.年，今天.月，今天.日））；
tabController=新的tabController(
长度：myList.length，
vsync:这个,，
);
jsonFileHelper.readToFile（）。然后（（res）{
firstDate=DateTime.From毫秒新纪元（res['firstDate']）；
差异=日期时间（今天.年，今天.月，今天.日）
.差异（首次日期）
.因戴斯；
设置状态（）{
myList.clear（）；
});
列表模板列表=新建列表（）；
对于（int i=0；i更新

我在这里提出的解决方案不再有效

我在重新定义“TabController”长度时也遇到了问题。
解决方案是在
initState
和
dispose
中创建
TabController
一次（也只创建一次）-假设TabController
length
只是一个最大长度，如果你认为你的应用程序的最大数量是100，那么使用固定的100。
非常感谢，我发现重复声明
TabController
存在类似问题。因此，我从上一页获得了数据，并通过一次性作业解决了问题。太好了！很高兴提供帮助！
