ZenEffectBuilder<T> class

A widget that responds to different states of a ZenEffect.

This widget automatically rebuilds when the state of the provided effect changes, showing the appropriate UI for each state (loading, success, error, or initial).

Optimized for production with reduced rebuilds and better performance.
