flutter finding out the title of the ToDoItem that has the highest price

Question

To-Do App

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,
  });}

I am trying to find the title of the ToDoItem which has the highest price

And the ToDoItem is being added to this:

List<ToDoItem> toDo= [];

Solution

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,
  );
  }

This is the code which i used in dart to sort your list . YOu could use the sorting logic from in here . it sorts your list in ascending order acc to price .

You can make a method of the Todo Class to get the highest price by storing the copy of the List in memory and then get the highest price..
