onError method
Called whenever an error
occurs and notifies BlocObserver.onError
.
In debug mode, onError throws a BlocUnhandledErrorException
for
improved visibility.
In release mode, onError does not throw and will instead only report
the error to BlocObserver.onError
.
Note: super.onError
should always be called last.
@override
void onError(Object error, StackTrace stackTrace) {
// Custom onError logic goes here
// Always call super.onError with the current error and stackTrace
super.onError(error, stackTrace);
}
Implementation
@override
// Default behavior is throwing an exception
void onError(Object error, StackTrace stackTrace) {
try {
super.onError(error, stackTrace);
} catch (err) {}
}
