ToastNotificationRegistry class

Registry for toast notification styles. Stores widget factories keyed by string IDs (e.g., "success", "warning"). Use ToastNotificationRegistry.register to add custom toast styles.

Supports both static ToastStyleFactory styles and data-aware ToastStyleDataFactory styles that receive data at call time.

Methods

clear() → void

Clear all registered styles (useful for testing).

register(String id, ToastStyleFactory factory) → void

Register a single toast style with the given id. The factory is wrapped to ignore data (backward compatible).

registerAll(Map<String, dynamic> styles) → void

Register multiple toast styles at once. Accepts both ToastStyleFactory and ToastStyleDataFactory values.

registerWithData(String id, ToastStyleDataFactory factory) → void

Register a data-aware toast style with the given id. The factory receives a Map<String, dynamic> data map at call time.

resolve(String id, Map<String, dynamic> data) → ToastStyleFactory?

Resolve a toast style by id, passing data to data-aware factories. Returns the ToastStyleFactory ready to build the widget, or the "success" factory with a debug warning if id is not found.

toString() → String

A string representation of this object.
