Flutter Error: no named parameter with the name "overflow"
You should also check the PR's of the library ;). This one fixes the problem. You can check the commits and change your code in your side. Or maybe wait some days, hours for the merge.
If you are really in need, you can fork the library, but for now just comment the code that references to it until the fix is merged
This error is usually caused by outdated(out-version) third party packages, the simplest solution is:
go to puspec.yaml and then remove all the third-party packages (remember which packages you are using) run "flutter pub get", then go to terminal do "flutter Clean" Then add all the packages with their latest version run "flutter pub get".
If the issue persists then try removing the only package that is responsible for the problem. in my case curvedNavigationBar was the problematic one, I removed the package then the issue was resolved.
I encountered with this kind of problem. After updating the flutter sdk, my problem was solved. Update your flutter sdk, it may work.
