Up to Ionic3, it was closely packed with Angular.js. So probably the navigation jobs were done by some Angular.js functionality. I can be wrong since I have not worked with Ionic or Angular.js before.
Ionic4 will be framework agnostic, written with Stencil.js and compiled with Stencil.js Compiler to Web Components standard components.
I wonder how navigation tasks will be handled, and by whom? Does Ionic4 have routing capabilities? Or it does not and developer's client-side router of choice must be used, especially I wonder the use case with Stencil.js since it has a router too. For example, how it should be used for a tabbed application Mark up and styles by Ionic, and routing with Stencil.js?
Ionic will now use angular router. it will make use of angular router-outlets. for the tabbed application markup, each tab will be provided with a named router outlet. Read more here:
Ionic/angular v4 router
Ionic 4 will now use angular routing method instead of default ionic 3 (push/pop) methods.
Must read the migration notes from ionic team.
Ionic has a component for simple navigation: https://ionicframework.com/docs/api/nav
But it's meant for simple navigation inside modals that doesn't affect the browser's url.
This navigation is controlled by calling methods on the element, so in Angular you have to use #ViewChild and it becomes complex to handle state and have deep navigation trees.
You should use a client-side router for most of your view to take advantage of code splitting and lazy loading your js bundle.

I was reading here about navigate with named routes, and in the document itself it says that it is no longer recommended to use it in many applications. Can anyone recommend me what is correct to use now? Or some article talking about.
Flutter docs suggests using go_router package for Navigation.
Explanation:
Limitations of trivial approach
Although named routes can handle deep links, the behavior is always the same and can’t be customized. When a new deep link is received by the platform, Flutter pushes a new Route onto the Navigator regardless where the user currently is.
Suggested Better Approach
Flutter applications with advanced navigation and routing requirements (such as a web app that uses direct links to each screen, or an app with multiple Navigator widgets) should use a routing package such as go_router that can parse the route path and configure the Navigator whenever the app receives a new deep link.

Which is the best way of Routing in a Flutter App?
I've tried named routes, routes array, flutter navigation 2.0. But I am still not sure which is the best.

Navigator 1.0 and 2.0 are usable. None is deprecated.
For mobile app only Navigator 1.0 is the best, I use onGenerateRoute field from MaterialApp and that's all I can handle all my routes and deep links. Some times, I used the Navigator widget for specific routes in app page but it's rare.
I'm trying to develop multi flow navigation using Shell & SplitApp controls.
I'm able to create shell and splitapp controls individually now I'm trying to provide navigation between shell and splitapp.
So the flow would be:
login View
Dashboard.
master details views
I'm using component.js for loading components and providing routing.
With this structure I'm able to navigate from master page to navigate page but I was struck at structuring the application.
I tried googling but didn't find anything useful.
I've followed the ui5 TDG for structuring the application.
UI5-TDG
Below is the sample image of dashboard view
Below is the sample image of master detail view
Am I the only one trying this kind of scenario or did I miss something?
Any suggestions/materials/resources on structuring of application would be greatly appreciated?
To navigate in your app the first thing to do is create a correct routing in Component.js file.
In the documentation you can see a mode to define the routing. But this mode is #deprecated from 1.28
The right way to compose the routing json is using routes and targets. You can see an example downloading the SDK and navigating in
openui5-sdk-1.28.11\test-resources\sap\m\demokit\master-detail\src\Component.js
If you have in mind the flow of your app you know each screen; in your example you have 3 screen: login, dashboard and cart; moreover you know that cart have a master and detail page (products and product).
Start immediately with splitapp (although some screens not have master) and compose router in the Component.js; you have:
3 routes: login, dashboard and cart. Targets are respectively ["login_detail"], ["dashboard_detail"], ["products_master", "product_detail"]
4 target: login_detail, dashboard_detail, products_master, product_detail, one for each view.
It is not clear to me how to "build" a UI with Appgyver Steroids. It looks like it uses only the CSS side of Ionic to render views, and not the javascript side.
This way is not possible to design UI with Ionic angular directives.
Am I wrong?
So my question is: which is the right way to design views in a Steroids app? Just by HTML and Ionic CSS classes? Is there a guide, maybe with example?
Is it possible to simply include Ionic javascript and use its directives? Some drawbacks?
Merituuli from AppGyver here.
We don't use the angular directives of Ionic because Steroids has methods to use native tabs and drawer elements, thus making the solution Ionic made unnecessary.
If you however want to include the Ionic angular directives you can do that by downloading the files you want to use from http://code.ionicframework.com/#, adding them to the /vendor folder and including them in your application.html.
If you need guides, tutorials and examples of using Steroids tabs, modals etc: https://academy.appgyver.com/categories/3-user-interface-and-design/contents
Hope this helps!
I developed GWT desktop browser application , before working on porting the Application for webkit browsers I need to have following doubts clarified:
Is it possible to map mulitple UiBinder template with the same View class?
Are the widgets consistent in look and feel for Desktop as well as webkit(mobile) browsers?
Thanking in advance.
Take a look at the mobilewebapp example which comes with the GWT SDK. There you can see, how an app can serve different views depending on the device by using deferred binding.
Using the first approach, you have different views for each device. So, you are free to choose different widgets for different platforms.
I want to share one the method that I tried, First of all instead of mapping view to viewimpl you can bind it to viewprovider, and then based on user-agent values you can return the appropriate instance to bind to.I implemented this in sample application and its working fine as of now.
