问题描述



I'm trying to map objects to actual widgets but keep getting this error


type 'List<Todo>' is not a subtype of type 'List<Todo>' of 'function result' where
  Todo is from package:todoapp/view/main_page.dart
  Todo is from package:todoapp/dto/todo.dart



Todo item is a simple class(todo.dart)


  const Todo({required this.id, required this.name, required this.isDone});

  final int id;
  final String name;
  final bool isDone;
}



and here is a mapping function


  List<Widget> getTodoListItems(List<Todo> todos) {
    return todos.map((todo) {
      return TodoListItem(todo: todo);
    }).toList();
  }



List view is initialized like that


...
 ListView(children: getTodoListItems(todos))
 ...




When I move the content of todo.dart to file with widget everything works fine but this is not quite of a solution for me, because this class is shared across different widgets.


Can someone please explain to me what is going on here? Apparently, this is the same object thus the same type, or at least it looks so


Edit:
There are many questions that look similar to this one, but they have different types which at least makes sense







Doubling string characters with recursion


Assume I have the string "my name is", how do I recursively return the string "mmyy nnaammee iiss"?

好的，这很愚蠢，但似乎颤动缓存了一些东西。重新启动项目并重新安装应用程序有帮助
