Avalonia Inside Shell reduces the complexity of mobile/desktop application development by providing the fundamental features that most applications require, including:
A single place to describe the visual hierarchy of an application.
A common navigation user experience.
A URI-based navigation scheme that permits navigation to any page in the application

<StyleInclude Source="avares://AvaloniaInside.Shell/Default.axaml"></StyleInclude>To use a ShellView in your application, you can add it to your XAML file like this:
<ShellView>
<!-- Your application content goes here -->
</ShellView>You can register navigation using the Host and Route elements. Host can be used to group pages under a common root, such as a TabControl. Here's an example:
<ShellView Name="MyShellView">
<Host Path="main" Page="views:MainTabControl">
<Route Path="home" Page="views:HomePage">
<Route Path="confirmation" Page="views:SimpleDialog" Type="Modal"></Route>
</Route>
<Host Path="pets" Page="views:PetsTabControlView" Default="cat">
<Route Path="cat" Page="views:CatView"></Route>
<Route Path="dog" Page="views:DogView"></Route>
</Host>
<Route Path="product" Page="shopViews:ProductCatalogView">
<Route Path="filter" Page="shopViews:ProductCatalogFilterView" Type="Modal"></Route>
</Route>
<Route Path="setting" Page="views:SettingView">
<Route Path="profile" Page="views:ProfileView"></Route>
</Route>
</Host>
</ShellView>And to navigate to a specific page, we can use the Navigator property of the ShellView, as follows:
await MyShellView.Navigator.NavigateAsync("/main/home/confirmation", cancellationToken);
Each page that is currently on top of the navigation stack has access to the navigation bar's title and navigation item. In hierarchical hosts, the currently selected item in the host will be the one that has access to the navigation bar. For example, in the case of /home/pets/cat, the page associated with the cat would be able to modify the navigation bar. This can be done by setting the NavigationBar.Header and NavigationBar.Item properties, as shown in the code snippet below:
<UserControl xmlns="https://github.com/avaloniaui"
x:Class="ShellExample.Views.ShopViews.ProductCatalogView"
NavigationBar.Header="Products">
<NavigationBar.Item>
<Button Content="Filter" Command="{Binding FilterCommand}"></Button>
</NavigationBar.Item>
...
</UserControl>IItem is the base interface for all items that can be added to the ShellView's content. It has the following properties:
Route is a type of IItem that represents a navigation route in the ShellView. It has a Page property that specifies the view associated with the route, as well as an optional Type property that specifies the navigation type, And Path is the property to register navigate.
Host can be used to group pages under a common root, such as a TabControl.
It has a Page property that specifies the view associated with the host, as well as an optional Default property that specifies the default child route. as well as a Children property that specifies any child Route objects.
SideMenuItem is another type of item that can be used to display navigation options in the ShellView's side menu. It also inherits from IItem and has the following properties:
Icon: An icon to display next to the item's label in the side menu.
Title: The text label to display for the item in the side menu.
Path: The path of navigation.
