bouncer

Bouncer debounces actions and makes sure any outdated answers will be ignored.

Problem statement

When user actions lead to starting several concurrent requests to some slow resource, there can be 2 problems:

1. exhausting of the resource
2. answers coming in random order

This library aims to solve both problems.

See example for reference.

Usage

instead of

  var response = await _longRunningRequest(parameters)
  _responseHandler(response);

let's debounce:

  _debounceSubscription = TimerBouncer(Duration(milliseconds: 200)).debounce(
    request: () => _longRunningRequest(parameters),
    responseHandler: _responseHandler,
    oldSubscription: _debounceSubscription,
  );

don't forget to dispose _debounceSubscription when it's no longer in use.

  @override
  dispose() {
    _debounceSubscription?.cancel();
    super.dispose();
  }
