pls i have been strugling with section 3.7 for about 2days now and i seem not to find a solution to the bug.


onChanged: (String newValueSelected) {

// Your code to execute, when a menu item is selected from dropdown

},

The error i'm getting is

The argument type 'void Function(String)' can't be assigned to the parameter type 'void Function(String?)?'.
