@DaniyarGilimov Regarding the back button functionality on Android, you can use a WillPopScope() and GlobalKey<NavigatorState>() as seen in this example: https://medium.com/coding-with-flutter/flutter-case-study-multiple-navigators-with-bottomnavigationbar-90eb6caa6dbf
How do you popstack with this implementation?
There's some additional information and a version of the example that integrates with the back button here: flutter/flutter#18740 (comment)
ok thanks for responding, I'll look into it.
Actually my question is this; I have seen the gist and what I seek to achieve is popping the stack once I click on the bottom navigation Item once I'm deep in the navigation stack. Say I move two levels deeper on the home bottom Item, once I click on the home Icon , I should return to the home screen.
Hi ! Thanks for this ! Is there a way to control one navigator from somwhere else ? For example, when clicking the home button, the inner home navigator goes to the 1st page ?
Hello,
Thanks for the code.
With this solution I can't pass arguments over the road with pushNamed, you have a solution ?
I'm trying to implement this kind of listPage and detailPage (Both should have bottom navigation. When i click item in listPage, it should open detailPage with bottom Navigation Bar, and when i click a button in detailPage: it should open new page without bottom navigation bar).
This solution perfectly work: places Bottom Navigation Bar when i open detailPage, however, now i can't open a new route without bottomNavigation (Bottom Navigation always stay at bottom, in every route, even if i don't want it).
