扑扑中的容器的onTap要调用回调以及容器的setState

Question

I am new to dart and flutter. I want to execute a callback onTap of a container as below:

final VoidCallback onClick;

onTap: ()  {
  widget.onClick; // this is the callback function
  setState((){
    isClicked = !isClicked;
  });
},

However, when I execute the above code the callback is not executed. However, when I write the code as below it is executed:

onTap: widget.onClick,

How do I achieve to execute the callback ?
