ReactiveNotify<T> class

ReactiveNotify is a class that extends SingletonState to manage global state reactively. It ensures that only a single instance of state per key exists, providing methods to set and reset the state.

Example usage:

final connectionState = ReactiveNotify<ConnectionElement>(() => ConnectionElement.connected);

// Access and modify the state
connectionState.setState(ConnectionElement.error);
print(connectionState.value); // Output: ConnectionElement.error

Factory constructor to create and manage a single instance of ReactiveNotify per key.

Properties

hashCode → int
The hash code for this object.
no setterinherited
hasListeners → bool
Whether any listeners are currently registered.
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
value ↔ T
The current value stored in this notifier.
getter/setter pairinherited

Methods

addListener(VoidCallback listener) → void
Register a closure to be called when the object changes.
inherited
dispose() → void
Discards any resources used by the object. After this is called, the object is not in a usable state and should be discarded (calls to addListener will throw after the object is disposed).
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void
Call all the registered listeners.
inherited
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that are notified when the object changes.
inherited
resetState() → void
Resets the state to its default value.
setState(T newValue) → void
Sets a new value to the state and notifies listeners.
toString() → String
A string representation of this object.
inherited
when({required T newState(), required void onCompleteState(T data), void onError(Object error, StackTrace stackTrace)?}) → void
Abstract method where you can execute callback on finish setState.

Operators

operator ==(Object other) → bool
The equality operator.
