I wrapped my code in a StatelessWidget instead of StatefulWidget, by doing so, i now fixed the problem. CheckboxListTile is now working thank you all for helping. This is the screenshot of my code sample before and after. [![enter image description here][1]][1]

I also rename my class name to MySales

I assume you want to toggle between true and false upon clicking the CheckBoxListTile.

Edit the following code inside your onChanged:

onChanged: (bool? value){
 isChecked = !isChecked;
}

onChanged provides nullable bool

final ValueChanged<bool?>? onChanged;

onChanged: (bool? value){
 isChecked = value ?? false;
}
