Rx<T> class

A simple reactive wrapper that notifies listeners when its value changes.

This is a lightweight alternative to more complex reactive programming libraries like RxDart. It's suitable for simple state management needs within the notification wrapper package.

Example usage:

final counter = Rx<int>(0);

// Listen to changes
counter.listen((value) {
  print('Counter changed to: $value');
});

// Update the value (triggers listeners)
counter.value = 1;

Methods

clearListeners() → void

Removes all listeners.

dispose() → void

Disposes of the reactive value and closes the stream.

listen(void callback(T)) → VoidCallback

Adds a listener that will be called whenever the value changes.

listenWithPrevious(void callback(T previous, T current)) → VoidCallback

Adds a listener that will be called with both the previous and the new value on every change.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

removeListener(void callback(T)) → void

Removes a specific listener.

toString() → String

Returns the current value as a string.

override

update(T updater(T current)) → void

Updates the value using a function and notifies listeners if changed.

Operators

operator ==(Object other) → bool

Checks equality based on the current value.
