SwiftPersisted(T initialValue, String _key, StorageBackend _storage, {T fromJson(Map<String, dynamic>)?, Map<String, dynamic> toJson(T)?, List<MigrationConfig<T>>? migrations, int? currentVersion})

Properties

fromJson → T Function(Map<String, dynamic>)?

final

hashCode → int

The hash code for this object.

no setter, inherited

hasListeners → bool

Whether any listeners are currently registered.

no setter, inherited

rawValue → T

Gets the value without registering as dependency (for internal use)

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

toJson → Map<String, dynamic> Function(T)?

final

value ↔ T

Gets the current value and registers this SwiftValue as a dependency

getter/setter pair, inherited-getter, override-setter

Methods

add(double value) → void

Available on Rx<double>, provided by the RxDoubleExtensions extension

Adds a value to the reactive double and updates it.

add(int value) → void

Available on Rx<int>, provided by the RxIntExtensions extension

Adds a value to the reactive integer and updates it.

add(String value) → void

Available on Rx<String>, provided by the RxStringExtensions extension

Adds (concatenates) a string to the reactive string and updates it.

addGST(double percent) → void

Available on Rx<double>, provided by the RxDoubleExtensions extension

Adds GST to the reactive double.

addGST(double percent) → void

Available on Rx<int>, provided by the RxIntExtensions extension

Adds GST to the reactive integer.

addListener(VoidCallback listener) → void

Register a closure to be called when the object changes.

inherited

applyPercent(double percent) → void

Available on Rx<double>, provided by the RxDoubleExtensions extension

Applies a percentage to the reactive double (adds percentage).

applyPercent(double percent) → void

Available on Rx<int>, provided by the RxIntExtensions extension

Applies a percentage to the reactive integer (adds percentage).

assertType([String? message]) → Rx<T>

Available on Rx<T>, provided by the RxTypeSafety extension

Assert type at runtime

chain() → ReactiveChain<T>

Available on Rx<T>, provided by the RxTypeSafety extension

Create a reactive chain

clear() → Future<void>

Clear persisted value

discount(double percent) → void

Available on Rx<double>, provided by the RxDoubleExtensions extension

Applies a discount percentage to the reactive double (subtracts percentage).

discount(double percent) → void

Available on Rx<int>, provided by the RxIntExtensions extension

Applies a discount percentage to the reactive integer (subtracts percentage).

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

migrate() → Future<void>

Migrate data manually (useful for testing or manual migration)

mul(double value) → void

Available on Rx<double>, provided by the RxDoubleExtensions extension

Multiplies the reactive double by a value and updates it.

mul(int value) → void

Available on Rx<int>, provided by the RxIntExtensions extension

Multiplies the reactive integer by a value and updates it.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

notifyListeners() → void

Call all the registered listeners.

inherited

notifyListenersTransaction() → void

Available on ChangeNotifier, provided by the TransactionNotifier extension

Notifies listeners, respecting transaction context.

removeGST(double percent) → void

Available on Rx<double>, provided by the RxDoubleExtensions extension

Removes GST from the reactive double.

removeListener(VoidCallback listener) → void

Remove a previously registered closure from the list of closures that are notified when the object changes.

inherited

roundTo(int decimals) → void

Available on Rx<double>, provided by the RxDoubleExtensions extension

Rounds the reactive double to a specified number of decimal places.

sub(double value) → void

Available on Rx<double>, provided by the RxDoubleExtensions extension

Subtracts a value from the reactive double and updates it.

sub(int value) → void

Available on Rx<int>, provided by the RxIntExtensions extension

Subtracts a value from the reactive integer and updates it.

tax(double percent) → void

Available on Rx<double>, provided by the RxDoubleExtensions extension

Applies a tax percentage to the reactive double (adds percentage).

tax(double percent) → void

Available on Rx<int>, provided by the RxIntExtensions extension

Applies a tax percentage to the reactive integer (adds percentage).

toggle() → void

Available on Rx<bool>, provided by the RxBoolExtensions extension

Toggles the reactive boolean value.

toString() → String

A string representation of this object.

inherited

toTyped() → TypedRx<T>

Available on Rx<T>, provided by the RxTypeSafety extension

Create a typed version

update(T newValue) → void

Updates the value and notifies listeners if changed

override

Operators

operator ==(Object other) → bool

The equality operator.
