bottom navigation bar pub.dev packages doesn't work with me Flutter

Question

I've tried to use different packages from pub.dev for navigation bar such as this one https://pub.dev/packages/curved_navigation_bar . but ALL of the packages give me an error when I import them although I've been working on this project for a while now and I used various packages they're all working fine.

Does anyone know what the problem is or if the problem from the packages or from my project?

these are some more of the packages I tried to use https://pub.dev/packages/awesome_bottom_navigation https://pub.dev/packages/persistent_bottom_nav_bar_v2

this my pubspec.yaml

Answer 1

hope you are fine,

You need to add more info about the problem, because here we don't understand where the problem exactly is, more explanation will be useful.

First package you mentioned and it works fine! screeenshot , source code screenshot

Answer 2

The problem was that pubsepc.lock does not add the new dependency when adding it to pubspec.yaml

I pressed the download icon in the top right corner of the pubspec.yaml, the ctrl+s and writing flutter pub get in the terminal wasn't enough.
