When Shell.NavBarIsVisible="False" open and close the flyout programmatically is not working

[Ainur13]

Description

I want to create custom button to show and hide flyout, but when I hide navbar in xaml by "Shell.NavBarIsVisible="False" I can't programmaticaly do it by using "Shell.Current.FlyoutIsPresented = true/false"

Interesting fact: when I swipe, flyout opens and after that my custom button, that opens flyout programmaticaly, starts to work!

Steps to Reproduce

1. Create app with flyout shell
2. Hide it by "Shell.NavBarIsVisible="False"
3. Try to use "Shell.Current.FlyoutIsPresented = true" to open flyout

Same issue encountered on Android devices. I suggest Shell should have an option to let developer choose to make Hamburger Navigation Button visible on every page or not. Currently, if the back button is presented, flyout menu (Hamburger Navigation Button) doesn't show up on Android/iOS.

Still an issue in MAUI on .NET 7. Adding the following line:

Shell.Current.CurrentPage.Layout(new Rect(0, 0, Shell.Current.CurrentPage.Width + 1, Shell.Current.CurrentPage.Height + 1));

after Shell.Current.FlyoutIsPresented = true; is still current workaround.

Encountering this with Shell.NavBarIsVisible="False" set in my view.xaml (contentpage) with a custom hamburger to trigger Shell.Current.FlyoutIsPresented = true net7.0 in VS 17.6.5

@TheLankyScottishNerd This works great though thank you very much!

Same with the Shell: Cannot open shell flyout when initial page has Navbar hidden (NavBarIsVisible="False") - Android · Issue #16927 · dotnet/maui (github.com)
