About #

AsyncValueNotifier is an asynchronous variant of ValueNotifier that coalesces multiple value assignments within the same event‑loop turn into a single notification dispatched in a later microtask.

Key benefits:

• Avoids synchronous listener re‑entrancy corrupting sequential logic.
• Prevents common Flutter "setState()/markNeedsBuild during build" style exceptions by deferring callbacks until after the current stack unwinds.
• Optionally cancels notification if value reverted during the same event loop turn.
• Optionally ignores duplicate listener registrations.

Installation #

1. Run the following command in your project directory:

flutter pub add async_value_notifier

2. Add the following code to your dart file:

import 'package:async_value_notifier/async_value_notifier.dart';

Usage #

Almost the same as ValueNotifier. For more information, please check example or API reference.
