CodePudding user response：

onChanged provides nullable bool

final ValueChanged<bool?>? onChanged;

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

CodePudding user response：

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;
}
