functional_listener 4.1.0

An rx like extension methods on ValueListenable type, that lets you work with ValueNotifiers almost like with Streams

[4.1.0] - 02.10.2024

• adding debounce as extenstion method on Listenable

[4.0.0] - 29.9.2024

• Following the findings of https://github.com/escamoteur/functional_listener/issues/13 we no longer destroy the listener chain when the last listener is removed. Because this might change the behavior of your app this is seen as a breaking change and therefore the change to 4.0.0. Please observe if this leads to increasing memory usage

[3.0.0] - 19.07.2024

• added optional error handler for CustomValueNotifier in case one of the listeners throws an Exception
• added listen() extension method for normal Listenable

[2.3.1] - 28.02.2023

• stupid bug fix

[2.3.0] - 28.02.2023

• added async() extension method

  /// ValueListenable are inherently synchronous. In most cases this is what you
  /// want. But if for example your ValueListenable gets updated inside a build
  /// method of a widget which would trigger a rebuild because your widgets is
  /// listening to the ValueListenable you get an exception that you called setState
  /// inside a build method.
  /// By using [async] you push the update of the ValueListenable to the next
  /// frame. This way you can update the ValueListenable inside a build method
  /// without getting an exception.
  ValueListenable<T> async();

• CustomValueNotifier got a new property asyncNotification which if set to true postpones the notifications of listeners to the end of the frame which can be helpful if you run into Exceptions about 'calling setState inside a build function' e.g. if you monitor the CustomValueNotifier with the get_it_mixin and you update it inside the build function. Default is false.
