I’m encountering a TypeError with the message:

Type '(Job) => ListTile' is not a subtype of type '(dynamic) => Widget'

in my Flutter app when trying to build a widget by passing a callback. The callback type is defined as:

final Widget Function(T) listItemBuilder;

in a class:

class ListPageBuilder<T extends Model> extends StatefulWidget

In the calling code, I instantiated ListPageBuilder with:

ListPageBuilder(
  listItemBuilder: (Job item) {
    return ListTile(
      key: Key(item.pk!),
      title: Text(item.title),
      subtitle: Text(item.description),
    );
  },
);

where Job inherits from Model. I expected this to work since Job is a subclass of Model, and ListTile is a Widget.

How can I resolve this issue?
