ZenEffect<T> class

A reactive effect that manages async operations with loading, data, and error states Uses the Zen reactive system for consistent API and optimal performance

Available extensions

Constructors

ZenEffect.new({required String name})

Properties

data → Rx<T?>
The current data value - using Rx for consistent reactive behavior
no setter
dataWasSet → RxBool

no setter
error → Rx<Object?>
The current error, if any - using Rx for consistent reactive behavior
no setter

no setter
hashCode → int
The hash code for this object.
no setterinherited
isDisposed → bool

noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
reset() → void
Reset the effect to initial state
run(Future<T> operation()) → Future<T?>
