Nested tabbed pages and their own "go scope"?

[leoshusar]

Hi! I am creating multiple nested tabbed pages like this

What I want to do:

• from main page you open user info
• • on user info you can switch between user's roles, permissions...
• • here you can open some role detail
• • • on role detail you can switch between role's permissions, users assigned to this role...
• • • here you can open open some another user info

basically you can go in cycle like user info -> role info -> user info -> role info...

Now the problem. I want, when you press the back button, go back one page in the stack. Even if you change tab on that page, I don't want to go back to previous tab, but the whole page.
You're here:
main -> user info -> role info -> user info -> role info
Back:
main -> user info -> role info -> user info
Back:
main -> user info -> role info
and so on.

This doesn't work since when you use push to navigate to a new page and then go to navigate between tabs on that page, it clears the stack - because that's what go does.
And when I tried to use push for navigating between tabs too, I got an exception (is this bug or expected behavior?):

════════ Exception caught by widgets library ═══════════════════════════════════
The following assertion was thrown building InheritedGoRouter(goRouter: Instance of 'GoRouter'):
Assertion failed:
..\…\widgets\navigator.dart:3470
!keyReservation.contains(key)
is not true

but I guess even if it worked, it would add each tab change to the stack, right? And the back button would just switch to the previous selected tab?

So, is there any way to achieve this? If not, I've got an idea for a feature request how this might be done.

Not yet but it's definitely on the list for the future (although we're not quite sure of the right way to do it yet: #222).
