Why am I unable to add and get data with Hive so it saves?

Question

I am trying to save values with Hive so that they are saved even after my app is closed. This is the code I am running:

@override
  void initState() {
    super.initState();
    box = Hive.box('exerciseBox');
  }

  addInfo() {
    box.put('Exercise 1', exercise1);
    box.put('Exercise 1 Time', exercise1time);
    return Text("");
  }

  getInfo() {
    exercise1 = box.get('Exercise 1');
    exercise1time = box.get('Exercise 1 Time');
    return Text("");
  }

@override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Column(
        mainAxisAlignment: MainAxisAlignment.spaceEvenly,
        children: <Widget>[
          SizedBox(
            height: 20,
          ),
          const Text(
            'Schedule:',
            style: TextStyle(fontSize: 30),
            textAlign: TextAlign.left,
          ),
          if (exercise1 != "") ...[
            addInfo(),
            getInfo(),
            one(exercise1),

There is more code after this but this is where I add and get data. But after I close app and open it exercise values are not saved. Pls help! Why isn't data saved?!

Please add box.flush() after put statement.

I added it, but there's still no difference. I added it after box.put('Exercise 1 Time', exercise1time); – nsa41620 Apr 16 '23 at 20:39
how do you declare box? – Rahul Apr 16 '23 at 20:55
I do "late Box box;" – nsa41620 Apr 16 '23 at 21:02
Do I need to close box? – nsa41620 Apr 17 '23 at 01:12
