Error code:

Error message:

    The argument type 'List<String>' can't be assigned to the parameter type 'List<SearchFieldListItem<dynamic>>'.dartargument_type_not_assignable
Couldn't infer type parameter 'E'.

--

Tried to infer 'String' for 'E' which doesn't work:
  Return type declared as 'List<E>'
              used where  'List<SearchFieldListItem<_>>' is required.
The type 'String' was inferred from:
  Parameter 'element' declared as     'E'
                      but argument is 'String'.

Consider passing explicit type argument(s) to the generic.

Answer 1

The error means that you are passing a List of string into a List that accepts SearchFieldListItem object with a type of dynamic(any type). Try to add the items in your list into and List with the given object.
