isCompletedFailed property
bool
isCompletedFailed
Returns true only if the action has completed (the 'after' method already ran), but either the 'before' or the 'reduce' methods have thrown an error. If this is true, it indicates that the reducer could NOT complete, and could not return a value to change the state.
Implementation
bool get isCompletedFailed => isCompleted && (originalError != null);
