• 初始化tabs
• 初始化tabConroller

tabs.clear();
tabs.addAll(customTabs);
_tabController = TabController(length: tabs.length, vsync: this);
setState();

---

方案B

return DefaultTabController(
  length: tabs.length,
  ...,
  button(
    onPress() {
        DefaultTabController.of(context).animateTo(0);
    }
 )
);

注： DefaultTabController.of(context).animateTo(0) 写在build外不生效
