Flutter: Keep BottomNavigationBar When Push to New Screen with Navigator

Question

In iOS, we have a UITabBarController which stays permanently at the bottom of the screen when we push to a new ViewController.

In Flutter, we have a bottomNavigation

Answer 1

You could actually place a placeholder inside body so the structure like this

- AppBar
- body (dynamic content from placeholder)
- BottomNavigationBar

Then you would have another class as a placeholder So each time you tap on the BottomNavigationBar it will refresh content of the body

One example I found is here https://willowtreeapps.com/ideas/how-to-use-flutter-to-build-an-app-with-bottom-navigation

and here but a litte too complex and not working for me https://medium.com/@swav.kulinski/flutter-navigating-off-the-charts-e118562a36a5
