Flutter - RaisedButton onPressed 有多个条件

Question

Just move to flutter and little bit frustration about multiple condition in raisedbutton onpressed.

I have bool buttonDisabled1 and bool buttonDisabled2 . I want if buttonDisabled1 == true AND buttonDisabled2 == true (both of them == true), so onPressed = null , it works.

However, if buttonDisabled1 or buttonDisabled2 == false (ONE of them is false) onPressed not null anymore.

My goal is:

buttonDisabled1 == true AND buttonDisabled2 == true -> onpressed null;
buttonDisabled1 == false AND buttonDisabled2 == true -> onpressed null; 
buttonDisabled1 == true AND buttonDisabled2 == false -> onpressed null; 
buttonDisabled1 == false AND buttonDisabled2 == false -> onpressed not null;

Thanks in advice:)

Below my code, none of them works.

Widget build(BuildContext context) {
  bool buttonDisabled1 = true;
  bool buttonDisabled2 = true;

RaisedButton(
  child: Text('Click'),
  onPressed: buttonDisabled1 && buttonDisabled2 ? null : (){},
),
}

RaisedButton(
  child: Text('Click'),
  onPressed: (buttonDisabled1 && buttonDisabled2) ? null : (){},
),

RaisedButton(
  child: Text('Click'),
  onPressed: ((buttonDisabled1) && (buttonDisabled2)) ? null : (){},
),

Answer 1

RaisedButton(
  child: Text('Click'),
  onPressed: !buttonDisabled1 && !buttonDisabled2 ? (){} : null,
),
