How to CSV mapping from import in flutterflow?

Custom Code

I am trying to built csv importer to supabase

The UI will lookg something like this

csv

I am able to bring headers from csv using custom code,

but dropdowns part as list view is facing issue,
Tried many ways like using custom functions & all but to send to next step is difficult can't figure out

Can solution, method style that would work to import

Thanks

What have you tried so far?

custom functions & actions so send into dropdown & page state to update from dropdown

Did you check FlutterFlow's Documentation for this topic?
