can update barrierDismissible from page

[developer-medan]

I make app that open this modal. page are consist pageUpdateProfile, pageSetting (barrierDismissible = true). Sometime when page expired token, i push new page called pageExpiredToken in this modal, i want user cannot hide by tap barrier. the only way to dismissible is by tap button close in the page in this modal, so i need to update barrierDismissible = false. but if token is not expired while other page is opened, this barrierDismissible is true. is this feature exist?

Hi, @developer-medan 👋

Currently, when the modal is visible, it is not straightforward to update the barrierDismissible feature. However, I think this might work and let me know if it does:

WoltModalSheet.show(
  context: context,
  modalDecorator: (child) {
    // Wrap the modal with `ChangeNotifierProvider` to manage the state of 
    // the entire modal. You can use any state management solution that you like.
    return ChangeNotifierProvider<MyViewModel>(
      builder: (_, __) => MyViewModel(),
      child: child,
    );
  },
  modalTypeBuilder: (context) {
   // here you watch for the view model changes. When the state updates because the 
   // isTokenExpired value changes, it will rebuild the modal.
   bool isTokenExpired = context.watch<MyViewModel>().state.isTokenExpired;
   return WoltModalType.bottomSheet().copyWith(barrierDismissible: isTokenExpired),
  }
);
