Allow Changing AppShell at runtime

[jrahma]

Description

Please add an option to change the AppShell at runtime

Public API Changes

this is the AppShell:

<?xml version="1.0" encoding="utf-8" ?>
<Shell
    x:Class="Muffin.Mobile.AppShell"
    xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
    xmlns:local="clr-namespace:Muffin.Mobile"
    Shell.FlyoutBehavior="Disabled">
    <ShellContent
        Title="Home"
        ContentTemplate="{DataTemplate local:MainPage}"
        Route="MainPage" />

    <ShellContent
        Title="Home"
        ContentTemplate="{DataTemplate local:Signin}"
        Route="Signin" />

    <ShellContent
        Title="Home"
        ContentTemplate="{DataTemplate local:OnBoarding}"
        Route="OnBoarding" />
</Shell>

and in App.xaml.cs:

MainPage = new Mobile.AppShell()<MainPage>;

Or:

MainPage = new Mobile.AppShell()<Signin>;

Or

MainPage = new Mobile.AppShell()<OnBoarding>;

Intended Use-Case

Many apps needs to change the MainPage for different scenarios.

What's actually stopping you from doing it? Do you get an error? I'm doing it in my app, and it seems to work.

MainPage = new Mobile.AppShell()<MainPage>;

I tried this but did not work:

App.Current.MainPage = new Mobile.AppShell()<Signup>;

CS0119: 'Signup' is a type, which is not valid in the given context

[Ghostbird]

What do sharp brackets after a value mean? I don't know this syntax.

Did you mean new AppShell<Signup>()?

[jrahma]

It means I have different pages that I want them to be my main without having ti use NavigationPage so when the user is already signed in then the AppShell's MainPage is called MainPage or or HomePage and if not then the AppShell's MainPage is called Signin

[Ghostbird]

Don't you have a single AppShell? I don't think you want to change the app shell at all. It seems you just want to navigate.

[jrahma]

Let me explain it.

I have the same pages that I need to open like MyProfile and it should be a main page when the user did not complete the profile so when the use is not signed in then the main page is Signin and when the user signed in with incomplete profile then the main page is MyProfile and then they profile is completed then the main page is MainPage

[Ghostbird]

Yes, that sounds like you want to navigate. I think the article I linked will help you.

Note that in all your cases the app's MainPage doesn't change. The MainPage is always the AppShell.
