+/// An alternative to [Timer.periodic] that ensures its callback is only being run once.
+///
+/// Using [Timer.periodic] can cause your function to run in parallel with itself. For example:

+/// ```dart
+/// void main() => Timer.periodic(Duration(seconds: 1), twoSecondDelay);
+///
+/// void twoSecondDelay(_) async {
