Package Overview

Package selection guidance compiled from public package information, community data, and project usage.

The throttling package provides async helper classes for implementing throttling and debouncing in Dart applications. It enables developers to control the rate at which functions are executed, preventing excessive calls during rapid events such as user input or network requests. With built-in listener support, it simplifies managing delayed or rate-limited operations across platforms. Ideal for optimizing performance in reactive UIs and real-time data handling.

Use cases

  • Rate-limiting user input events
  • Optimizing network request frequency
  • Improving UI responsiveness
  • Managing real-time data updates
  • Reducing redundant computations
  • Handling scroll or resize events

Key features

  • Throttling and debouncing utilities
  • Async-compatible with listeners
  • Cross-platform support
  • Simple API for rate limiting
  • Built-in cancellation handling
  • Support for both sync and async functions

Suitable for

  • Developers building responsive Flutter apps
  • Teams needing event rate control
  • Apps with frequent user interactions
  • Real-time data processing scenarios
  • Performance-critical applications

Considerations

  • Requires understanding of async flow
  • May add latency if thresholds are too strict
  • Not suitable for immediate execution needs
  • Listeners must be managed to avoid memory leaks
  • Best used with state management patterns

Using

See a demonstration of use at dartpad.dev

Throttling example
final thr = Throttling<void>(duration: const Duration(milliseconds: 200));
thr.throttle(() {print(' * 1');}); // print ' * 1'
await Future<void>.delayed(const Duration(milliseconds: 100));
thr.throttle(() {print(' * 2');});
await Future<void>.delayed(const Duration(milliseconds: 100));
thr.throttle(() {print(' * 3');}); // print ' * 3'
thr.close();
Debouncing example
final deb = Debouncing<void>(duration: const Duration(milliseconds: 200));
deb.debounce(() {print(' * 1');});
await Future<void>.delayed(const Duration(milliseconds: 100));
deb.debounce(() {print(' * 2');});
await Future<void>.delayed(const Duration(milliseconds: 100));
deb.debounce(() {print(' * 3');});
await Future<void>.delayed(const Duration(milliseconds: 200));
// print ' * 3'
deb.close();
