I use flutter web I put a checkbox for users. The problem is that the page contains a different TextField.So, in the event that the user selects one of the Checkbox options, a page refresh occurs.Then all TextField data is reloaded and all data that was previously inserted is deleted.The problem is caused by setState(()).But I can't delete it if the setState checkbox is deleted. The checkbox doesn't work.

  bool _checkbox = false;

 Checkbox(
    value: _checkbox,
    onChanged: (value) {
      setState(() {
        _checkbox = !_checkbox;

      });
    },
  );

How can this problem be solved without deleting the data from the fields?

Thank you
