flutter_smart_debouncer 1.0.0

A unified package providing debouncing utilities and smart Flutter widgets (TextField, Button, etc.).

flutter_smart_debouncer

flutter_smart_debouncer is a unified toolkit for taming noisy inputs. It combines production-ready debouncing utilities with polished Flutter widgets so you can guard API calls, smooth out text entry, and prevent accidental double submits using a single dependency.

Debouncing coalesces a burst of events into a single callback once the user pauses. It keeps search boxes snappy, throttles autosave traffic, and prevents repeated taps on important buttons.

Quick start

Add the package to your app:

dependencies:
  flutter_smart_debouncer: ^1.0.0

Debounce anything in Dart code

final searchDebouncer = Debouncer<void>(
  delay: const Duration(milliseconds: 300),
);

Future<void> onQueryChanged(String value) {
  return searchDebouncer(() async {
    await searchApi(value);
  });
}

SmartDebouncerTextField

SmartDebouncerTextField(
  delay: const Duration(milliseconds: 250),
  decoration: const InputDecoration(labelText: 'Search'),
  onChangedDebounced: (value) {
    debugPrint('Searching for $value');
  },
);

SmartDebouncerButton

SmartDebouncerButton(
  delay: const Duration(milliseconds: 600),
  child: const Text('Submit'),
  onPressed: () {
    debugPrint('Submitted once');
  },
);

What's inside?

• ✅ Battle-tested debouncer with leading/trailing edges, maxWait, cancel, and flush APIs
• ✅ Widget wrappers for text fields and buttons built on top of the same debouncer
• ✅ Stream helpers, throttle utilities, and reactive DebouncedValue
• ✅ Thorough tests, lints, and an example Flutter app demonstrating both styles

Example app

See example/lib/main.dart for a Flutter demo that simulates an API call using the core Debouncer and shows the smart widgets in a material UI.

Run it with:

flutter run
