onError method
The callback will be executed on error.
If you want to continue the error , call handler.next
.
If you want to complete the response with some custom data directly,
you can resolve a Response
object with handler.resolve
and other
error interceptor(s) will be skipped.
If you want to complete the response with an error message directly,
you can reject a DioError
object with handler.reject
, and other
error interceptor(s) will be skipped.
Implementation
@override
void onError(
DioError err,
ErrorInterceptorHandler handler,
) {
if (level == Level.none) return handler.next(err);
logPrint('[DIO]<-- HTTP FAILED: $err');
return handler.next(err);
}
