[Spec] Add better parameters for navigation args

[PureWeen]

Description

Currently the navigation args provide no useful information:

• NavigatedToEventArgs
• NavigatingFromEventArgs
• NavigatedFromEventArgs

We added these args very early on so that we'd be setup to add better information later on.

Here are some suggested additional properties

• PreviousPage
• CurrentPage
• The navigation behavior performed (pop, push, reset, etc...)

Any News around this one @PureWeen ? This is the main show stopper for me to adopt shell?

It has been +2 years since I've reported this bug for MSFT and they didn't come up with a proper solution, so to save your precious time consider completely ditching MAUI AppShell for now, and use the following library to workaround this issue: https://github.com/naveasy/Naveasy

Any news on this @PureWeen @jfversluis @samhouts ?

.NET 9 is just around the corner and I have serious doubt if they are gonna release it despite of asking for it since early days of .NET 6 many years ago with a bunch of details, samples and etc as you can see on the following Issue (which they shamelessly closed without any solution when it reached 2yo and reached the 1st most commented issue here on MAUI GH repo, instead of keeping it open until this api design flaw gets fixed).

In the OnNavigatedTo event of Page, PreviousPage of NavigatedToEventArgs is declared as internal, so it cannot be used.

Is there a reason why you declared PreviousPage as internal? I want PreviousPage to be declared as public.

namespace Microsoft.Maui.Controls { public sealed class NavigatedToEventArgs : EventArgs { internal NavigatedToEventArgs(Page previousPage) { PreviousPage = previousPage; }

internal Page PreviousPage { get; }  <-- Why internal?

} }

create a new PR for it. There was one, which was closed to no activity from the author.

See How to use PreviousPage which is hidden internally.
