Shell navigation with modal page does not show title view #21321

Open dk-mushiyoke opened 7 months ago

dk-mushiyoke commented 7 months ago

Description

When using shell navigation to display a modal page, the title view does not show even with Shell.NavBarIsVisible set to True

As per #15498 the same issue should have been fixed in 8.0.0-preview.7.8842, however I am able to reproduce both in 8.0.6 and 8.0.7

Steps to Reproduce

  1. New maui project
  2. Add a new page with Shell.NavBarIsVisible="True" and Shell.PresentationMode="ModalAnimated"
  3. Register route for new page ("ModalPage" in repro)
  4. Hook up MainPage button clicked event to execute Shell.Current.GoToAsync("ModalPage");
  5. Build and run in android emulator, click button and observe the modal page

Im getting the same issue. I cannot believe this has not fixed untill now.

MAUI document shows only about using GoToAsync way for Shell navigation instesad of using the NavigationPage way.

I can see the Modal from Shell GoToAsync, does Not show Shell.TitleView, and also the Tabbar as well. The Tabbar not showing issue is from Xamarin. I cannot believe the two issues are still there. https://github.com/xamarin/Xamarin.Forms/issues/13477

I think I need to use PushModal way to see if it works with Navigation titleview.... I have migrated two XF apps to MAUI(Prism navigation) already and this is my third migration. This time I wanted to use Shell.

I can do workaround like adding Title as customView or template etc, but this is not ideal. Please fix this issue

Any update? I ended up adding a custom view as the titleview in Grid. I reported bugs during the transition from Xamarin.Forms (XF) to .NET MAUI. None of them have been fixed even though they can be easily reproduced.
