IOS: Popup, how to stick window to bottom over "home" button.

[SergTomcat]

I need to lower Popup to the very bottom of the screen.

Can you help removing bottom gap?

Possibly related to dotnet/maui#27542

I think you'll need to look at disabling UseSafeAreaInsets on iOS for this to give you the outcome that you want

@bijington, @stephenquan
There are some problems:

1. SafeAreaInsets only applicable to Pages, Popup has it's own rendering handler, and I need to solve this for Popups especially.
2. VBZelin's solution implies to remove safeareas on every page and manually add grids with artificial top and bottom insets, which leads to redundancy of layout, especially when you have several dozens of pages. Also I don't think it will affect Popup (didn't test because of item 3)
3. I tried ios:Page.UseSafeArea in Xaml and Page.On.SetUseSafeArea(false) and it doesn't remove the gaps for some reason. SetPrefersHomeIndicatorAutoHidden just makes bottom line invisible but does not remove the gap. And, finally, popup makes bottom line visible again (see item 1).

I need help with forcing community toolkit popup layout to ignore safe areas.

Well this will change soon because Popups will be making use of a page based implementation #1581

What if you change UseSafeAreaInsets in the calling page?

I tried to call Page.On[iOS].SetUseSafeArea(false) on every Page and Shell in their constructors (both before and after InitializeComponent call to be sure), for experiment, seems it doesn't have any effect.

InitializeComponent();

PlatformSpecific.SetupPage(this);

.....

public static void SetupPage(Page page)
{
	page.On<iOS>().SetUseSafeArea(false);
}

You need to use another control like BottomSheet. I'm not sure if a popup can help you achieve the result.

I found not very elegant workaround by extending MauiPopup class and overriding ViewDidLayoutSubviews, where I replaced measurments and margins of PopoverPresentationController with my values afterwards.

Hope that tuning of margins, overlay color, etc. will be available in future versions without overloading and duplicating half the code.
