Hi 🙂 you were almost there : just add ! to value so isChecked = notValue

like this :

class _MyAppState extends State<MaterialApp> {
  bool _myBoolean = false;

  @override
  Widget build(BuildContext context) {
    return Center(
      child: Checkbox(
        value: _myBoolean,
        onChanged: (bool? value) {
          setState(() {
            _myBoolean = value!; // WILL rebuild
          });
        },
      ),
    );
  }
}
