Maui Shell weird navigation issue with timing of ApplyQueryAttributes and Page Lifecycle

[meopoc]

Description

My app navigates to a MainPage with a menu that then navigates through other pages in the app until it reaches a page that requires a Flyout Menu (at which point I set the Shell.Current.FlyoutContent).

So

MainPage > PageA > PageB > PageWithFlyoutMenu

I'm performing the navigation as follows

MainPage to PageA: await Shell.Current.GoToAsync($"PageA", true);

Lifecycle event order: Constructor > ApplyQueryAttributes > OnAppearing > OnNavigatedTo

PageA to PageB: await Shell.Current.GoToAsync($"PageB");

Lifecycle event order: Constructor > ApplyQueryAttributes > OnAppearing > OnNavigatedTo

PageB to PageWithFlyoutMenu: Shell.Current.FlyoutContent = IPlatformApplication.Current?.Services.GetService<MenuPage>(); await Shell.Current.GoToAsync($"///PageWithFlyoutMenu-1");

Lifecycle event order: Constructor > OnAppearing > OnNavigatedTo > ApplyQueryAttributes

The issue here is that ApplyQueryAttributes is the last to be invoked.

AppShell is as follows:

<Shell
x:Class="****.AppShell"
xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:local="clr-namespace:****.Views"
xmlns:localDetail="clr-namespace:****.Views.DetailPages"
Title="****">

<ShellContent
    Title="MainPage"
    ContentTemplate="{DataTemplate local:MainPage}"
    FlyoutItemIsVisible="False"
    Route="MainPage"
    Shell.FlyoutItemIsVisible="False" />

<ShellContent
    Title="PageWithFlyoutMenu-1"
    ContentTemplate="{DataTemplate localDetail:PageWithFlyoutMenu-1}"
    Route="PageWithFlyoutMenu-1" />

<ShellContent
    Title="PageWithFlyoutMenu-2"
    ContentTemplate="{DataTemplate localDetail:PageWithFlyoutMenu-2}"
    Route="PageWithFlyoutMenu-2" />

</Shell>

And I have the following routes registered:

Routing.RegisterRoute("PageA", typeof(PageA));
Routing.RegisterRoute("PageB", typeof(PageB));

Can anyone shed any light on why this would be?

Thanks in advance

Yea :-/ the OnNavigatedTo unfortunately don't fire in the most consistent order

I have a PR here building towards this effort https://github.com/dotnet/maui/pull/23420

@PureWeen HI, Thanks for the reply. Seems odd considering the query properties are likely to be needed in the page lifecycle events. It looks to me that ApplyQueryAttributes is the issue as this fires after the OnAppearing too.

Do you know of any workaround whereby I can use query properties in a lifecycle event?

[meopoc]

On further investigation this only appears to be an issue the first time the "PageWithFlyoutMenu" is navigated to. I've attached another repo with console logging and fixed a couple of navigation issues.

Please note the Shell.Current.FlyoutContent is set just prior to navigating to "PageWithFlyoutMenu"

FYI only tested on Android.
