Check if there is a Future.delayed or not

Question

I want to check if there is any Future.delayed function ongoing. Thanks for any help.

    Future.delayed(duration, () async {
      await aFunction();
    });

    bool isAnyDelayedAtTheMoment=?;

Answer 1

As theiskaa suggested, i did like this:

bool isAnyDelayedAtTheMoment=true;

Future.delayed(duration, () async {
      await aFunction();
      isAnyDelayedAtTheMoment=false;
});

Answer 2

as an option you can use Completed full code:

import 'dart:async';

void main() {
  final completer = Completer();

  Future.delayed(Duration(seconds: 1), () async {
    await aFunction();
    completer.complete();
  });

  print('isCompleted: ${completer.isCompleted}'); // false

  Future.delayed(Duration(seconds: 2), () async {
    print('isCompleted: ${completer.isCompleted}'); // true
  });

}
