function as parameter with generic object return type in dart

Question

I have a function defined as

final Function<Future<PageableModel<T>>>(String?) elementBuilder;

The compiler shows a compile error at "Future": Expected to find '>'. Is it possible in Dart to define a generic object as the return type of a function defined as variable.

Solution

That is not valid syntax. You probably meant:

final Future<PageableModel<T>> Function(String?) elementBuilder;

@Donatic How is that awkward syntax? Function return types in Dart normally go to the left of the function declaration. It's also not any longer than what you originally tried.
