How to reset things daily in Flutter?

Question

I have a To Do List with things to do daily like 'Drink Water' and so on. So now I want that when the user has checked a To Do, the next day it should be unchecked again. How can I implement this?

Right now my Code looks like this:

class ToDoScreen extends StatefulWidget {
  const ToDoScreen({Key key}) : super(key: key);

  @override
  _ToDoScreenState createState() => _ToDoScreenState();
}

class _ToDoScreenState extends State<ToDoScreen> {
  List toDos = ['Train Today', 'Drink Water'];
  bool value = false;

  void addToDo(String newToDo) {
    setState(() {
      toDos.add(newToDo);
    });
    Navigator.of(context).pop();
  }

  void newEntry() {
    showDialog(
        context: context,
        builder: (BuildContext context) {
          return AlertDialog(
            content: TextField(
              onSubmitted: addToDo,
              decoration: InputDecoration(
                  border: OutlineInputBorder(
                      borderRadius: BorderRadius.circular(10)),
                  icon: Icon(Icons.text_snippet_outlined),
                  labelText: 'New To Do'),
            ),
          );
        });
  }

As Yeasin Sheikh said in the comment, first of all you need to save your data somewhere, otherwhise you don't have nothing to reset.

I read in the comments that you'd like to use Firebase.

So I suppose you'll be storing data in Firebase Firestore.

The best way to perform such reset, in my opinion, is to use a Firebase Function (docs).

You could see them as server side code. From there you can define a function to access your DB and reset the data.

To trigger the function once a day, you should use an external service to call the function.
