wrap abstract method
This method is deprecated in favor of GlobalWrapError.wrap.
The reason for this deprecation is that the GlobalWrapError works in the same way as the action's ReduxAction.wrapError, while WrapError does not.
The difference is that when WrapError returns null
, the original error is
not modified, while with GlobalWrapError returning null
will instead
disable the error.
In other words, where your old WrapError returned null
, your new GlobalWrapError
should return the original error
:
// WrapError (deprecated):
Object? wrap(error, stackTrace, action) {
if (error is MyException) return null; // Keep the error unaltered.
else return processError(error);
}
// GlobalWrapError:
Object? wrap(error, stackTrace, action) {
if (error is MyException) return error; // Keep the error unaltered.
else return processError(error);
}
Also note, GlobalWrapError is more powerful because it can disable the error, whereas WrapError cannot.
Implementation
Object? wrap(
Object error,
StackTrace stackTrace,
ReduxAction<St> action,
);
