I am just creating a simple ToDo App in Flutter. I am managing all the todo tasks in the list. I want to add any new todo task at the beginning of the list. I am able to use this workaround kind of thing to achieve that. Is there any better way to do this?
void _addTodoInList(BuildContext context){
String val = _textFieldController.text;
final newTodo = {
"title": val,
"id": Uuid().v4(),
"done": false
};
final copiedTodos = List.from(_todos);
_todos.removeRange(0, _todos.length);
setState(() {
_todos.addAll([newTodo, ...copiedTodos]);
});
Navigator.pop(context);
}
Use insert() method of List to add the item, here the index would be 0 to add it in the beginning. Example:
List<String> list = ["B", "C", "D"];
list.insert(0, "A"); // at index 0 we are adding A
// list now becomes ["A", "B", "C", "D"]
