How do I cancel Future.delayed?

Question

How can I cancel/stop a Future.delayed? I read this other question: how can i cancel Future.delayed function calling and someone answered with this possible solution: https://dart.academy/how_cancel_future/, but I don't know how to use it in my code, I don't have a List of Data like the example, I just don't want the code inside the Future.delayed be executed in certain case.

await Future.delayed(Duration(seconds: myDuration)).then((_){    checkAnswer("");   jumpToNextQuestion();  }); 

Answer 1

Use a Timer.

  Timer t = Timer(Duration(seconds: myDuration), () {     checkAnswer('');     jumpToNextQuestion();   });   // and later, before the timer goes off...   t.cancel();
