SignalObserveExtension<T> extension

Extension on ReadonlySignal to provide fluent observe API.

This allows calling .observe() directly on any signal for a more ergonomic syntax:

final counter = SignalsWatch.signal(0);

// Instead of:
SignalsWatch.fromSignal(counter, builder: (value) => Text('$value'))

// You can write:
counter.observe((value) => Text('$value'))
on

Methods

observe(Widget builder(T), {Key? key, void onInit(T value)?, Function? onValueUpdated, void onAfterBuild(T value)?, void onDispose(T value)?, bool shouldRebuild(T newValue, T oldValue)?, bool shouldNotify(T newValue, T oldValue)?, bool equals(T a, T b)?, Duration? debounce, Duration? throttle, void onError(Object error, StackTrace stack)?, Widget errorBuilder(Object error)?, Widget loadingBuilder()?, String? debugLabel, bool debugPrint = false}) → SignalsWatch<T>

Observe this signal and rebuild when it changes.

Select a specific part of this signal's value and only rebuild when that part changes.

Transform this signal's value and observe the result with error handling.
