exceptionFor method

UserException? exceptionFor(
  1. Object actionOrTypeOrList
)

Returns the UserException of the actionTypeOrList that failed.

The actionTypeOrList can be a Type, or an Iterable of types. Any other type of object will return null and throw a StoreException after the async gap.

Example:

if (context.isFailed(SaveUserAction)) Text(context.exceptionFor(SaveUserAction)!.reason ?? '');

Implementation

UserException? exceptionFor(Object actionOrTypeOrList) =>
    StoreProvider.exceptionFor(this, actionOrTypeOrList);
