I created a sign up screen and I used a pageview in it. That page view has a controller and that controller also works with a smooth page indicator I added. The page view is also connected to a button I created using a container I designed wrapped in a gesture detector. The page changes to the next when the button is pressed and finally on the last page the button signs up the user. I want the button to be inactive and designed differently on all pages until the condition are met.
The first page requires an email
The second page requires a password
The third page is to confirm the password
You can set the onPressed Callback of a button to null and the button will be disabled.

onPressed: condition_is_met ? (){} : null,

I created a login screen using SwiftUI.
When I press a login button (after the validation of email and password), it navigates to a ViewController.
Login state is stored in a userDefault Boolean for use later when the app is launched again.
In SceneDelegate, userDefault is checked--if it istrue, the main screen is shown; otherwise the login screen is shown.
In a View Controller I created a itemBar Logout button which navigates back to the login screen when it is pressed.
I managed to implement the above logic.
The problem happens when I successfully log in then close the app in a simulator and open again.
When I press the Logout Bar item, the app isn't responsive and does not navigate back to the Login screen.
I tried to use the Coordinator pattern without success. Any help is appreciated!
Instead of popping the previous route I'm trying to navigate to a new route when user presses the back button.
think I'm in the route1() and push to the route2(). now I want to push to the route3() when the user presses the back button. and in the route3() when he/she press the back button again he get to route1().
What I'm doing right now is that I use the WillPopScope() in route2() and when the user presses the back button in android i call the pushReplacement(). but when I get to route3() and press the back button I get to the route2().
When on route1(), try pushing route3() and immediatly after that puse route2(). This way route2() will be on top of the stack, and when the back button is pressed route3() will replace it with route1() right below it.

I have a navigation based template application, I parse data into table view.
I want to put a login screen before parse the data. I did the login screen and and succeed the login check.
My problem is that when the user presses the button I change the view to the tableview.
what a way should I draw? I want to learn how can i close the tableview screen when the app launched and after pressed the button I want to show the tableview.
If you are using a navigation based template, you could simply push another view on the stack, or you could have the second table view as the first screen, and push the login over the top. pressing on a button to login will pop the login screen off the stack to reveal the main tableview screen.
I have put the login details in the user preferences screen.
