TabBarView controller index with useState change

[ThomasAunvik]

Describe the bug When changing a State and changing the tab index trough the controller at the same time. It would seem to ignore the state.

To Reproduce

https://github.com/ThomasAunvik/flutter_state_bug_tabbar

https://github.com/ThomasAunvik/flutter_state_bug_tabbar/blob/41f409c1c1790a50385bdbd98ab99d41b9984155/lib/main.dart#L54-L66

Remove the commented out //tabController.index = 1; to make the bug happen.

Minimal Example:

final submittedValue = useState<String?>(null);

TabBarView(
  controller: tabController,
  children: [
    FirstWidget(
      submit: (value) {
        submittedValue.value = value;
        tabController.index = 1;
      },
    ),
    PreviewWidget(
      submittedValue.value,
    ),
  ],
)

Expected behavior State should also reflect on the second page.

Attempted this with normal flutter state, seems to be a not-issue for flutter_hooks.

Found similar issues after a bit more searches when it was generally flutter problem.
