问题描述
待办事项
class TodoItem{
final String id;
final String title;
final Color color;
final int price;
final IconData icon;
final String todoListId;
const TodoItem({
@required this.color,@required this.id,@required this.todoListId,@required this.price,@required this.title,@required this.icon,});}
List<TodoItem> todo= [];
解决方法
void main(){
List<ToDoItem> _myList = [];
_myList.add(ToDoItem('10',100));
_myList.add(ToDoItem('30',400));
_myList.add(ToDoItem('40',2));
_myList.add(ToDoItem('20',200));
_myList.sort((a,b)=>a.price.compareTo(b.price));
for(ToDoItem items in _myList)
print(items.id + ',' + items.price.toString());
}
class ToDoItem{
final String id;
final int price;
const ToDoItem(
this.id,this.price,);
}
这是我在dart中用来对列表进行排序的代码。您可以从此处使用排序逻辑。它将按照价格升序对列表进行排序。
