Grouped content, navigable by bottom tabs.I like to remove all pages from the navigation stack and make my current page the new root page. How can I do that? Whole navigation is done with the new Shell navigation calling Shell. GoToAsync route or the Flyout Menu. I tried collecting the current stack from Shell.

NavigationStack and Shell. NavigationStackbut the only element in there is null for any reason. I am using the latest Xamarin 4. I've reproduced the issue. NavigationStack[0] returns null, App. RemovePage page will not work and an exception occurs. Someone has faced the similar problem and it's being solved.

Pay attention to this case. Forms Shell includes a URI-based navigation experience that uses routes to navigate to any page in the application, without having to follow a set navigation hierarchy.

In addition, it also provides the ability to navigate backwards without having to visit all of the pages on the navigation stack. So, you cannot get the page from shell's NavigationStack. I don't see the relation between this and the quote before. We shouldn't it be possible to remove pages from the Navigation Stack? Thank you for that hint, thank for trying to reproduce.

As this is a major release, you would be right to expect some pretty big changes. It also introduces a powerful route based URI navigation service in addition to the existing navigation service. The real power of Shell, however, is underneath. This new architecture introduces the foundation for future Xamarin. Forms development that will enable more expressive animations, transitions, and interactions.

To quickly get started using Shell, use the new Shell template in Visual Studio shipping today. For more details on using Shell, check out our updated documentation:.

You may recall version 2. This pattern has proven to work as well as expected, and is now the new performance standard for the renderers that Shell implements. Be sure to review any custom controls or third party controls that depend upon these renderers to make sure everything works as expected, if not better.

Should you find that you need to continue using the old-style renderers, we have introduced a flag for that purpose. In your MainActivity. From this point forward everything implements ImageSource.

The tooling builds an Application Shell and let's the developer focus on building their application. Forms Shell is a great new way to build apps in Xamarin. It was released in Xamarin. Welcome to the Shell Era: Xamarin. This means the team builds a comprehensive prototype using any of the popular mockup tools. This allows the designers, stakeholders, developers and anyone else get a hands on look at the app without talking about the implementation details. Instead of designing an app, we are going to use a design already put together from Dribble.

Looking at the Did You design, and notice how custom the TabBar is. There are 2 main Tabs. In the center of the TabBar there is a big plus icon that brings the user to a new task screen. This is a fantastic design and I am ready to get started, but building the New Task button in the TabBar is going to be complex.

As a developer, I really want to use Xamarin Shell. Create the basic App Shell to get started and define all of your navigation items.

There are going to be 3 main pages and 3 main tabs. This isn't exactly what we want, but it does accomplish the design goals. We now have 3 pages and 3 tabs that configure our navigation with minimal code. The next step is implementing a custom render to really take advantage of the shared APIs. To simplify our implementation and custom renderer code we need to define a shared control that stores information about the large plus icon center tab.

Adding a custom renderer for Shell Renderers is very different that any other custom renderer that you may have built. This is because the ShellRenderer is the main entry point for all things Shell. Once the code is using the ShellRenderer every renderer from that point on is just instantiated. This makes is easy to create custom implementations, but requires an additional step when building any custom Shell functionality.

This is the entry point for any custom Shell behaviors you wish to implement. Forms Android Platform code knows what renderer to load into memory. If you don't do this nothing will work!Since the release of Xamarin Forms 4. Since one of my highest ranking blog posts is how to create a login page with Xamarin Forms.

I thought it was time to revisit the topic and look at how to implement a login page using the Shell. So what is so special about a login page? Well, to state the obvious, the user should only be able to exit it after entering a correct login. Further, the user should not be able to leave the login page, i. And finally once successfully authenticated, the user should not find the login page when navigating back.

So let's see how we can capture the user on a page and then ensure that this page is no longer on the navigation stack while using Shell. So let's get going with the UI flow of a possible login experience. Our app has the following screen flow: All of our pages have to be registered with the Shell. Note that the first ContentPage in the Shell. If the app was not a total fake on the business logic side. It might be using a Token-based flow; this is where one would check if the app still has a valid token and can go directly to the main screen or the user has to log in.

Beautiful load animation, right? When using Shell, you define the kind of navigation on the target page. Well because otherwise all your Android users could just simply press the Android back button and weasel their way out of your carefully crafted login process. Now let's add a registration page. Here we define the standard push navigation:? We can do this in the code behind of the AppShell. RegisterRoute "registration", typeof RegistrationPage ; Now we can navigate from the login page to the registration page by as follows: Shell.

So as soon as the user has logged in, we display the main page of the app. Which is again defined in the AppShell. So now that we are in the app. Sometimes you will want to present the user with the option to logout. Shell gives us an easy way to define a flyout menu. So a nice place to add our logout is as a new entry in the flyout right?

Instead of defining a flyout item, it will be better to use a menu item. In general think of flyout items as areas of your app and menu items as actions in the menu. The logout is less an area and more an action. This could be during start-up, resume or on a rainy Tuesday. Whatever the requirement, you can simply invoke the navigation similar to above, and the user will be navigated to the login screen.
