Is it possible to make the NavigationBar scrollable? My goal is to make a NavigationBar, so you can add up to 15 diffrent Items, if you want.
Thanks for your answers.
That is not possible, and you don't find navigation bars to be scrollable, good UI design features a few elements at the most in the nav bar.
For a scrollable solution, please check out Tabs: https://material.io/components/tabs/flutter
