run method

void run(void action())

Runs action now if allowed, otherwise skips it (or queues it when trailing). throttler.run(save)

Implementation

void run(void Function() action) {
  final DateTime now = DateTime.now();
  if (_last == null || now.difference(_last!) >= interval) {
    _last = now;
    action();
    return;
  }
  if (!trailing) return;
  _queued = action;
  _timer ??= Timer(interval - now.difference(_last!), () {
    _timer = null;
    final void Function()? next = _queued;
    _queued = null;
    if (next != null) run(next);
  });
}
