delay method
Utility to delay some callback (or code execution). TODO: Add a separated implementation of delay() with the ability to stop it.
Sample:
void main() async {
print('+ wait for 2 seconds');
await 2.delay();
print('- 2 seconds completed');
print('+ callback in 1.2sec');
1.delay(() => print('- 1.2sec callback called'));
print('currently running callback 1.2sec');
}
Implementation
Future delay([FutureOr Function()? callback]) async => Future.delayed(
Duration(milliseconds: (this * 1000).round()),
callback,
);
