For those who get an error this is what I did...
I used
'onChanged: <String>(newValueSelected) {'
instead of 'onChanged: (String newValueSelected) {'

and I added
'value: _currentItemSelected, '
right after the '}' of 'onChanged {'

I hope it helps.

I was having a syntax error -The argument type 'void Function(String)' can't be assigned to the parameter type 'void Function(String?)?'(it was occurring during the execution of OnChanged handler in the DropdownButton widget), which was later solved by using the correct data type of String? but u didn't face that issue, can u please explain the difference between String? and String

Thanks for the video. How do I store a value behind e.g. Rupees. Let's say we want a currency calculator and we want the dollar/rupees exchange value behind the item rupees. How can I do that?

Sir,
I have used autocomplete in a flutter. it's working properly but I have more than (lakh) records in the table. in autocomplete the whole table first loading and then get ready for searching, it takes to much time to load and populated in the textbox. I want to show the result bases on entering a value in realtime means when users entering the word it should be getting from the table, not from the autocomplete stored data. Thanks

Thanks for the video. I'm trying to build a dropdownmenu that changes its menu items according to another input. I managed to change the list that loads into the dropdownbutton widget, but don't know how to make it refreshes itself. Can you give me some advices?
