Signal<T> class

A base-class that store a value of T and notify the listeners when the value is updated.

You can create a new Signal:

// usign `.signal` extension
final strSignal = "initial value".signal;
final intSignal = 0.signal;
final userSignal = User().signal;
// or usign the constructor class
final strSignal = Signal<String>("initial value");
final intSignal = Signal<int>(0);
final userSignal = Signal<User>(User());

You can get the value:

// usign a `value` getter
print(strSignal.value);
// or using the callable
print(strSignal());
// or using `toString` implicit
print("$intSignal");

You can set a new value:

// usign a `value` setter
strSignal.value = "change value";
// or using the callable
strSignal("change value");

You can use Lifecycle.willUpdate event for before the value is changed, or use Lifecicle.didUpdate event for after the value is changed:

Reactter.on(
  strSignal,
  Lifecycle.willUpdate,
  (signal, _) => print("Previous value: $signal"),
);

Reactter.on(
  strSignal,
  Lifecycle.didUpdate,
  (signal, _) => print("Current value: $signal"),
);

Use update method to notify changes after run a set of instructions:

userSignal.update((user) {
  user.firstname = "Leo";
  user.lastname = "Leon";
});

Use refresh method to force to notify changes.

userSignal.refresh();

If you use flutter, add flutter_reactter package on your dependencies and use its Widgets.
