I am building an app(Learning) and on first use the app it show authentication page with login and signup button if user click any one button and fill the fields it will be navigate to homePage.
Navigation :
Authentication Page=>login=>main page
Now the problem is I don't want users to get back to login page if they press back button on home page. Instead I want to exit the app.
How can I do it?
When you navigate from login to main page use Navigator method .pushReplacement() instead of .push() and that will replace the login page on Navigator stack. Which means that the main page will be the only one on the stack. Pressing the back button or calling method .pop(), in that case, will close the application.

How do you navigate from a modal popup?
I've opened a modal page using await NavigationService.PushModalAsync() which I'm using as a login page. With a successful login, I'm trying to close the modal and navigate to an account page.
await NavigationService.PopModalAsync();
await NavigationService.PushAsync();
The modal closes, but it will not show the page specified in the PushAsync Method.
Both lines of code run, no errors thrown.
The page the pushasync() goes to, displays fine if the login modal window is skipped.
The above code is in a [RelayCommand] method using community toolkit mvvm
What do I need to do to get the above to work?
Unfortunately your needs cannot be achieved. As mentioned in the figure above, the login page you created is a modal page, therefore it can navigate only to another modal page. When you call PopModalAsync, the login page pops up from ModalStack directly, meanwhile the (moldeless) page at the top of the NavigationStack will appear. And you call PushAsync to navigate to the account page in modal page, it doesn't work.
I've made a home page and a target page.
When the a target page button is pushed on the home screen,
I am checking if users are logged in and navigating them to a Login Page(Web).
After successful Login, the page is redirecting back to a target Page.
Here comes a problem. There is no way back to the Home Page.
Home -> Target Page -> Log-in(Web) -> back to Target Page(No histories left in navigator)
I am using Navigator.of(context).pushNamed(route)
No Appbar back button. physical device back button directs to go out from the app now.
Any ideas would be helpful
To help return to the previous screen
Navigator.of(context).pop()
Or read more about navigation in Flutter:
Navigation and routing
Use this
Navigator.of(context).pop()

The problem I’m asking is how to have a kind of page (call it SetupPage) that is only shown until the user presses a button on the screen. Then when the screen should show the next page(call it HomePage) and every time the app is opened after the button press, the normal page will be HomePage.
I’ve seen this general idea in many apps (sign-in and home page, enter phone number or school and main page, etc) and I would like to have it in my app! I’m thinking of using Navigator routes and having the stack be this at first:
(HomePage, SetupPage)
and then once the button is pressed I can pop SetupPage. But I’m not sure how to implement this.
I already have the SetupPage and HomePage classes made. I’m not doing a sign-in the SetupPage or anything like that. I’m not using FireBase in this app either.
You can use the Flutter package shared_preferences to save a Boolean that tell you at the start of the program is the button pressed or not.
In our Apple Watch swift application we have two controllers(Login and dashboard controller). After login user will land to dashboard page and after clicking on back button it is again landing to login page.
So, my requirement is that after clicking on back button on dashboard it should stay on same dashboard page.
So, How can I prevent back action and assign custom action once back button clicked in apple WatchKit application?
I think what you might be looking for is to call reloadRootPageControllers on WKInterfaceController:
https://developer.apple.com/documentation/watchkit/wkinterfacecontroller/2868441-reloadrootpagecontrollers
after successful login, and re-initialise your app's UI with the dashboard screen. This makes it impossible to go back to the login screen, and there will be no back button as the dashboard becomes the new root level app screen.
Hope this helps.
